Rule #1 of ocean critters: If it's obvious, it's poisonous.

Just assume everything under water is some how poisonous.

a lot of stuff is lethally sharp rather than poisonous.

Just don't touch anything underwater. Like, ever.

>>2338233
Hexapoda are deeply nested WITHIN Crustacea, not a sister group to them, so the name Crustacea still applies to the entire group by definition. The new name "Pancrustacea" was created because the entomologists got butthurt.
It's like calling reptiles "Panreptilia" because we realized birds have to be included. Luckily the ornithologists weren't as buttblasted about it.

Those are the two biggest instructing associations. I like NAUI more and am certified with them, but PADI's bigger. They basically do the same things—check their website and I'm sure there'll be a place for you to start getting certified nearby unless you live in a literal shithole.
You should totally get certified though—getting certified can be kind of a pain, and the bookwork's annoying, but it's SO worth it. Being able to breathe and swim around underwater is such a cool feeling, and you get to see so much more than snorkelers could dream of.

>>2340039
Nice beast! Getting the colours right is always an issue. At some point, I might invest in decent lighting to snap good pictures. Otherwise, it is hard to explain to surface people how beautiful it is.
That said, I have never done a night dive (too chicken).
Sea sickness is awful. Find yourself some shore dives!
>>2340058
>That said, I have never done a night dive (too chicken).
At night you see colors you wouldn't see at any other time because of the lantern and the setting in general is divine.
You should do it.
>Find yourself some shore dives!
There are none near me.
>>2340025
My two favorite dives were a reef dive near Pueta Vallarta, Mexico, or a really sick night dive off Catalina Island.
Favorite animals are nudibranchs, and I've met plenty!
>>2340025
I've gone diving in the Atlantic, Pacific, and the Red Sea. The Red Sea is definitely my favorite even though I saw more cool creatures in the Atlantic.
The Red Sea was fun because I got to dive through a bunch of ship wrecks and I did a night dive. The night dive was a little scary because I am admittedly scared of the dark and there were lion fish EVERYWHERE. The ship threw out a big light and we all had good deep-sea flashlights though so it was all good.
In the Atlantic I got to see fun things like lobsters, a nurse shark, and a sea turtle that kept trying to rest on a bald man's head.
I've seen more things and have more stories but I don't feel like typing them out ATM. Let me know if you want them or anything in particular

Crustaceans, Myrapods, and Insects are Mandibulates, but they are still distinct classes of Arthropod.
Also, have a life-recreation of an extinct Chelicerate. Jaekelopterus, most-massive example of sea scorpion, and Arthropod, ever recorded. It lived in freshwater and grew up to 2.5 meters in length. Its closest living relatives are horseshoe crabs and scorpions.

Of course, that hasn't changed. The ranks are different now though, Hexapoda are now just a subphylum of Crustacea, with Remipedia as the possible sister group. This is WITHIN the former Crustacea, not a basal split. That is what made the entomologists angry, so they renamed the group to Pancrustacea to prevent the shitstorm they knew would be heading their way. It has nothing to do with scientific discourse, this was just a matter of hurt pride.

I got a rabbit snail at the local fish store today, after verifying my tank was alright for it. I noticed that it's having a hard time traversing the gravel, but its not sick or anything because it was fine when it was on brick. Will it adapt over time, or should I move it to a sand-bottomed tank? I tried to look it up but there's sparse information.

Although I hear octopi dont live long as pets. I heard 6-8 months
It was a long, long time ago, but when I was a kid, you could buy them special order for about $80
I never kept one. But Im told its difficult because they figure their way out of the habitat and then once out, get confused and die from whatever the reverse of drowning is.

Horseshoe crabs are great. You gotta respect an animal that has remained almost completely unchanged for over 250 million years, through every major extinction event thus far.
It's just about time to start spotting them, too, in the Northern hemisphere anyway. The full moons of spring, especially June, is when the begin congregating on the shores to mate.

>You gotta respect an animal that has remained almost completely unchanged for over 250 million years, through every major extinction event thus far.
Still has to bow down to >>2341537 >>2341546, specifically Triops cancriformis. 300 million years and not "almost completely unchanged" but actually completely unchanged. The oldest fossils fit our modern species description and the only thing that has changed over the aeons is their average size. That's the record I think.
I always wonder why people assume old species like this are "primitive" or "less evolved". If you think about it they're a lot better at doing their thing than anything modern. They are so perfectly adapted for what they're doing that any change is detrimental, so they stay the same. As close to evolutionary "perfection" as you can get.
>>2342268
I goofed, it was over 450 million years.
>>2342272
Either way, both are impressive examples of finding what works very early on.
>>2342271

Well, the old ones are not species that exist today so Triops cancriformis still wins. Take that ocean spider freaks!

Fun fact about blanket octopuses:
>Tremoctopus violaceus exhibits the most extreme degree of sexual size-dimorphism known in any non-microscopic animal. Females may reach 2 m (6.6 ft) in length, whereas the males are 2.4 cm. The weight ratio is at least 10,000:1, and can probably reach as much as 40,000:1. The males have a large arm in a spherical pouch modified for mating, known as a hectocotylus. During mating, this arm is detached, and kept by the female in her mantle cavity until used for fertilisation. The male almost certainly dies shortly after mating.

That one in particular is from the Indo-Pacific.
If I had to guess what you saw in Cuba, maybe some sort of zoanthid coral like this pic? They come in a million color combinations, wouldn't doubt there is one with similar colors to the urchin.
>>2342364
Heh, turtles are that awesome.
In the Caribbean sea, some buddies had a fish (don't know which) staying along the belly of one of the divers during the whole dive. This smart guy used the divers to fend off predators and from time to time, dipped to catch a prey then would come back to safety.
Is it cruel to frag anemones?
>>2342364
How large was this turtle?
>>2342440
This was about 8 years ago but I don't believe it was any more than a meter in length
>>2342362
I actually did an informal study on it's aroma for a summer program in high school! I showed that presence of 2,6-Dimethyl-1-heptanol on food made food items much less palatable to multiple species of crabs that have been reported predators on Melibes. The chemical didn't seem to have an effect on other predators (anemones and rockfish).
After working with concentrated Melibe aroma for weeks, I'm 100% fine with never smelling that smell again.

Nah, these live inland instead of out at sea; though, they can be found in estuaries too. The baggy ones are called file snakes or elephant trunk snakes in general.

I go down to see them every year when they bread in NJ. Its crazy. I throw a bunch of dying ones back in because they get stuck every place and die in the sun. Buts its a really cool to me.

Water pressure and temperature effect the metabolism and internal pressure of aquatic life in the same way atmosphere does for land creatures.
Horseshoe crabs dwell in deep waters and only really come ashore for short periods.
Without the right parameters, most exotics that need those specific requirements will suffer various kinds of stress and die sooner than they could.
Similarly some creatures survive longer in captivity because they won't be exposed to predators and disease.
This shit really fucks up my desire for owning a variety of exotic creatures.

What was the sea lion doing? and was this diver in danger of dying?

adult horseshoe crabs are straightforward to keep in captivity (if you have the money - none of you do), the trick is breeding them. they won't mate in captivity. if you can establish a viable breeding line you would be richer than kings due to the fact their blood is so valuable for vaccinations.

See if searching "rubber eel" gives you anything similar? It's the common name given to a bunch of aquatic caecilians.
