You'd be hard pressed to find a vertebrate stranger than Atopodentatus.
I saw a horsehair worm in a small stream this week while backpacking. I'd seen enough of these Youtube videos to recognize it. It took me a good 3 minutes to work up the courage just to pick it up, and then I dropped it as soon as the "head" got near my fingers. I know it's harmless, but I couldn't unsee those videos.
Not sure if you count protists, but I think radialarians are pretty cool.
I think hanmerheads look pretty dingdong
Man o' War
> the Portuguese man o' war is not a common jellyfish but a siphonophore, which is not actually a single multicellular organism, but a colony of specialized minute individuals called zooids.
>These zooids are attached to one another and physiologically integrated to the extent that they are incapable of independent survival.
>The Portuguese man o' war lives at the surface of the ocean. The gas-filled bladder, or pneumatophore, remains at the surface, while the remainder is submerged
>Since the Portuguese man o' war has no means of propulsion, it is moved by a combination of winds, currents, and tides
>Although it is most commonly found in the open ocean in tropical and subtropical regions, it has been found as far north as the Bay of Fundy and the Hebrides.
Strong winds may drive them into bays or onto beaches. Often the finding of a single Portuguese man o' war results in the finding of many others in the vicinity.
>They must be treated with caution, and the discovery of a man o' war washed up on a beach may lead to the closure of the whole beach
The follow was found in the Hadal zone of the ocean, which has virtually no light and is comparable to what Jupiter's moon, Europa, may look like. It's deeper than Mount Everest is high, and since there is no light there is no food since photosynthesis cannot occur.
Pyrococcus CH1 was recently discovered in 2007.
>A novel hydrothermal site was discovered in March 2007, on the mid-Atlantic ridge during the cruise 'Serpentine'. At a depth of 4100 m, the site 'Ashadze' is the deepest vent field known so far.
>Smoker samples were collected with the ROV 'Victor 6000' and processed in the laboratory for the enrichment of anaerobic heterotrophic microorganisms under high-temperature and high-hydrostatic pressure conditions.
>Strain CH1 was successfully isolated and assigned to the genus Pyrococcus, within the Euryarchaeota lineage within the Archaea domain. This organism grows within a temperature range of 80 to 108 degrees C and a pressure range of 20 to 120 MPa, with optima for 98 degrees C and 52 MPa respectively.
> Pyrococcus CH1 represents the first obligate piezophilic hyperthermophilic microorganism known so far.
>Comparisons of growth yields obtained under high-temperature/high-pressure conditions for relative organisms isolated from various depths, showed clear relationships between depth at origin and responses to hydrostatic pressure.
>Cow sharks are considered the most primitive of all the sharks, as their skeletons resemble those of ancient extinct forms, with few modern adaptations.
>Their excretory and digestive systems are also unspecialised, suggesting they may resemble those of primitive shark ancestors.
>Their most distinctive feature, however, is the presence of a sixth, and, in two genera, a seventh, gill slit, in contrast to the five found in all other sharks
>Cow sharks are little known because they spend most of their lives in deep, cold oceans beyond the reach of divers.
>Greenland sharks are native to the North Atlantic waters around Greenland, Canada, and Iceland. They are the only true sub-Arctic shark and the only shark that can tolerate Arctic temperatures year round. They prefer very cold water (-1°C to 10°C).
>Greenland sharks have been observed at the water’s surface all the way down to 2,200 meters deep. They are sometimes seen resting on continental shelves and slopes at these great depths.
>Greenland sharks are one of the larger sharks out there, capable of growing to more than 20 feet long and weighing up to 2,500 lbs.
>The Greenland shark is an opportunistic predator that will eat just about any meat it finds, either dead or alive. They eat a lot of fish and there is some evidence that they ambush sleeping seals, but some scientists believe they are primarily scavengers. Some strange things have been found in Greenland sharks’ stomachs, including the remains of polar bears, horses, moose, and in one case an entire reindeer.
>The teeth on the upper jaw are narrow, pointed, and smooth, and anchor the food item as the lower jaw does the cutting. The teeth on the lower jaw are larger and broader and curve sideways. By swinging its head in a circular motion, the shark can cut out a round plug of whatever it’s feeding on.
>Greenland shark is one of the slowest swimming sharks in the world. They average a cruising speed of 0.3 m/s (0.76 mph), but are capable of short bursts of speed.
>Some estimates put the life span of Greenland sharks at over 200 years. Where does this number come from? One study found the sharks grow about 0.5 to 1 cm a year.
>reenland sharks contain high levels of trimethylamine oxide (TMAO; it helps regulate their osmotic pressure and also acts as a natural antifreeze). During digestion, TMAO breaks down into trimethylamine (TMA). TMA causes intestinal distress and neurological effects similar to extreme drunkenness. Eating too much can even lead to convulsions and death.
>>They must be treated with caution, and the discovery of a man o' war washed up on a beach may lead to the closure of the whole beach
we have them all the time
nobody gives a fuck
i've been lightly stung by one once, hurts like hell, gave me a nice ride to the hospital
For hard mode, what I mistook the OP image for a second
I remember seeing one of those washed up on the beach once. I was really young and it weirded me the fuck out, especially since the jellyfish we see washed up here are only about as big as a teacup.
>Grimpoteuthis spp, are known as the deepest living of all octopus species. They live on the seafloor or hover just slightly above it at depths of depths of 3000 to 4000 m (9800 to 13000 ft),
>The similarity of the ear-like fins protruding from the top of the mantle of the Dumbo octopus to the ears of the Disney character, Dumbo, the Flying elephant, led to the common name, dumbo. There are about 17 species of Dumbo octopus that belong to a group called “umbrella octopus,” because they are able to float with an umbrella-like look to their mantle. While these species can “flush” color as do more shallow species, their mouth structure is different. It has a degenerated radula-type opening that allows it to swallow prey whole instead of having to tear and grind it. This feeding characteristic unique to the genus Grimpoteuthis.
Totally looks like Pols Voice from Zelda NES.
Blue sea slugs are pretty wizard. There's something oddly tetrapod about them.
I haven't seen an Ocean Sunfish here yet. they seem so weird and amaze me.
Found these in my pony tank.
Water bears are awesome. I don't like that gif though. It is definitely not how a real water bear moves. That one was modeled after a terrestrial animal. You can see under the digitized computer rendered skin that there is a virtual skeleton and it's appendages have elbows and shoulders. A real water-bear would be more like a little worm and they are so small they are practically transparent. They just float around and latch onto food debris. Also, their heads come in many different shapes. But yea, water-bears are pretty cool doodz
I don't know about horsehair worms, but there are similar parasites that definitely do affect humans. You know, tapeworms and the like.And tapeworms are so common that if you go outside and scoop up some moist soil, you'll probably come in contact with eggs or a juvenile. They're everywhere, which is why personal hygiene like washing before eating and such is important.
Oh shit, don't remind me. That shit is so disgusting. I remember a friend of mine dated a girl and when he finally got intimate with her, she fucking had WORMS coming out of her ass. He was so disgusted he freaked out and she was like "But everyone has those"
lol. Of course he dropped her, but holy shit. It might be common, but I damn sure don't have them, and I don't intend on getting them. Some people must live like animals.
Not everyone, but a lot of kids who aren't clean.
Also pinworms aren't big enough that they'd really be noticeable; dunno WHAT the fuck she had going on.
Pinworms can be treated by over the counter methods or just certain diets.
If any of you find yourself with worms like these, or any kind of digestive parasite, and are too embarrassed/can't see a doc, then a really effective method often used in third world countries is to buy a pack of cigarettes. Take one apart and ingest all of the tobacco. Tobacco is a perfectly safe all natural insecticide. After it hits your gut you will shit out all of the parasites.
It's so safe and effective crows in cities are starting to line their nests with cig butts to protect their kicks from parasites.
seahorse babies. It's like horses in the ocean. I tame them
>no saiga antelope
>mfw realizing saiga antelope is probably not weird enough for /an/
sea lilies are pretty crazy, mostly because they're animals with a hugely plantlike body plan
Humans, I mean what the fuck they don't even have fur, feathers, or scales. They have four limbs but only walk on two of them. It doesn't make sense, their stomachs are exposed this makes it easy for predators to attack vital organs. Its a miracle they didn't go extinct since they aren't even strong or fast. I cant even find another creature as weird as them.
bretty interesting how the face and cranium changes physically but for thousands of years the body just loses hair and most of the differences are physiological. strong arms, torso/core, and legs are still prevalent today.
Not an animal, but
>The genus Prototaxites /ˌproʊtɵˈtæksɨtiːz/ describes terrestrial organisms known only from fossils dating from the Silurian and Devonian, approximately 420 to 370 million years ago. Prototaxites formed large trunk-like structures up to 1 metre (3 ft) wide, reaching 8 metres (26 ft) in height, made up of interwoven tubes just 50 micrometres (0.0020 in) in diameter. Whilst traditionally very difficult to assign to an extant group of organisms, current opinion is converging to a fungal placement for the genus. It might have had an algal symbiont, which would make it a lichen rather than a fungus in the strict sense.
>Tobacco is a perfectly safe all natural insecticide
Nicotine poisoning is a very real danger. You can die from it. One of the estimated thresholds for lethality is two cigarette's worth. Eat one and prepare to vomit a lot, but yeah, you'll get rid of the worms.
w-where is the eye? The thing I thought was an eye has a fringe around it.
Based on 20 % oral bioavailability of nicotine (Hukkanen et al. 2005) and assuming linear kinetics, an oral dose of 60 mg would give rise to a plasma concentration of about 0.18 mg/L. The literature reports on fatal nicotine intoxications suggest that the lower limit of lethal nicotine blood concentrations is about 2 mg/L, corresponding to 4 mg/L plasma, a concentration that is around 20-fold higher than that caused by intake of 60 mg nicotine. Thus, a careful estimate suggests that the lower limit causing fatal outcomes is 0.5–1 g of ingested nicotine, corresponding to an oral LD50 of 6.5–13 mg/kg.
and a cigarette weights what, 1-2g?
I was just a kid when one of these was found at the beach we went to at the gulf of Mexico. To my knowledge, the powers that be did not shut down the beach or even really respond with concern.
The Man o War itself was pretty cool looking. That little spine looked like it was flexing.
Nautilus eye is an interesting case, it is a primitive eye without lens, like a pinhole camera.
Ticks get inside mammal ears so I think it is possible. But the ocean is big and those animals aren't social so I guess parasites specialized on a structure that only they have would be uncommon.
>don't mind me, I just need to purge my FUCKING EYES
Sure they can, but I said fast not long distance. Human's average speed for short distance is 15 miles per hour, that is slower than lions which can reach up to 50 mph. So yes we can run for a longer amount of time, but we are still a hell of a lot slower to other species.
I think manta rays are very cool, but extremely weird.
>have barely been studied despite being huge interesting animals
>live for approximately 50-100 years
>only produce a few offspring their entire lives
>have the largest brains of all fish
>open ocean swimmers
>basically just a living pointy blanket
took forever to find this thing in my massive image collection
Supposedly they're tasty too
how the fuck does that happen
I can't help but think all this weird face architecture serves a very sophisticated purpose
This? The only other links I can find are from gawker and the Daily Mail, both of which aren't exactly known for truth in journalism. There was also that explorer guy who ended up with a beetle inside his ear. He just left it in there and bits of it fell out some months later.
That 'sometimes' is lower than my chances of getting cancer and ya, it's not so great at purging foreign objects that have evolved to ignore it. Get some deep in ear headphones though and try to keep them in your ears a whole day without adjusting them though. Unless you're native American or Asian (different ear wax structure) then you probably got about 4-6 hours before they start working their way out, without consideration to things like motion or sweating.
The human body is pretty neat man. Don't short sell it.
>That 'sometimes' is lower than my chances of getting cancer
Not at all, I have seen many cases, it is just solved faster and with less repercussions than cancer
>In Spinochordodes tellinii and Paragordius tricuspidatus which have orthopterans as their vector, the infection acts on the insect's brain and causes it to seek water and drown itself, thus returning the nematomorph to water.
This fucking abomination here
Evolved a fucking neck to snipe other spiders
How does this happen
best part is that males are venomous, dammit why didn't Perry ever us this being an agent and all?

Something that was not meant to exist.
eats chloroplasts, becomes plant
I am sure chewing tobacco would work as well. When I did chew I would swallow some of it to get buzzed.Also I guess I am a filthy person, only really wash my hands after taking a shit but I rarely get sick. Used to eat tons of dirt and fertilizer when I was a youngin'. Got that strong immune system.
Experience is only as creditable as how it's interpreted.
Ugh, can you people fucking stop? Holy shit whenever people talk about human evolution they are always so full of shit.
>le humans are so quirky and weak!
>le humans evolved big brains ;)
The fact is, the inbetween having the ability to make tools and having physical strength meant pre-human ancestors had to survive there too.
You know how they did it? BECAUSE HUMANS WERE NEVER EVOLUTIONARY TOP PREDATORS
Holy fuck, I cannot believe how few people can grasp this simple fucking concepts.
Gorillas and organtangs and chimps are NOT TOP PREDATORS
They are omnivores that are just as physically strong as they need to be to eat animals smaller then them, and fast/social enough to have a good chance against predators.
STOP COMPARING HUMAN EVOLUTION TO PRIMARY PREY ANIMALS LIKE ZEBRAS AND TOP PREDATORS LIKE LIONS YOU DUMB FUCKS HOLY FUCKING SHIT
They swim in the Saint-Lawrence river sometimes.
And a guy that was diving south of Sept-Iles met a 18 feet long greenland shark nose to nose. He shat his diving suit and nope'd to the surface.
Surprised no one mentioned this one yet.
I present to you the Suriname Toad
The olm, or proteus (Proteus anguinus), a salamander, is the only cave-dwelling chordate species found in Europe. In contrast to most amphibians, it is entirely aquatic; it eats, sleeps, and breeds underwater. Living in caves found in Dinaric Alps, it is endemic to the waters that flow underground through extensive limestone of karst of Central and Southeastern Europe, specifically southern Slovenia, the Soča river basin near Trieste, Italy, southwestern Croatia, and Herzegovina.
It is also occasionally called the "human fish" by locals because of its skin color, similar to that of white people (translated literally from Slovene: človeška ribica and Croatian: čovječja ribica), as well as "cave salamander" or "white salamander." In Slovenia, it is also known by the name močeril, which translates as "the one that burrows into wetness." It was first mentioned in 1689 by a local naturalist Valvasor in his Glory of the Duchy of Carniola reporting that after heavy rains the olms were washed up from the underground waters and made local people believe they saw a cave dragons' offspring.
This animal is most notable for its adaptations to a life of complete darkness in its underground habitat. The olm's eyes are undeveloped, leaving it blind, while its other senses, particularly those of smell and hearing, are acutely developed. It also lacks any pigmentation in its skin. It has three toes on its forelimbs, but two toes on its hind feet. It also exhibits neoteny, retaining larval characteristics like external gills into adulthood, like the American amphibians, the axolotl and the mudpuppy. The olm is the only species in the Proteus genus, the only European species of the Proteidae family.
Besides, human meat is probably not particularly tasty or filling, herbivore meat is generally plentiful, easier and nicer to eat. Humans probably would look and feel weird to predators (bipedal, loud, more dangerous than they look with weapons, associated with weird smells and fire..)
I am pretty sure social behaviour and the ability to manipulate tools has been more crucial to the development of humans than just being "smart". Being "smart" won't help much if you are alone and you can't pick anything up.
>Its a miracle they didn't go extinct since they aren't even strong or fast.
We have something else that makes up for it: endurance.
