The pistol shrimp is a pretty cool dude.
See that big claw of his? He can snap it shut hard enough to cause one of the loudest noises in the ocean, as well as cavitation bubbles and a pretty severe shockwave. He uses it to stun small fish and other shrimp so he can eat them.
If you're not familiar with cavitation, it's a pretty strange phenomenon. Basically, he's forcing a small area of vacuum to appear at the bottom of the ocean, which takes a great deal of energy. When the bubbles collapse, they produce a bright (but tiny) flash of light and an extremely brief burst of heat that's about equal to the temperature of the sun's surface.
They also hang out with these dudes
and use them as watchdogs. They both live in the same burrow. The gobi fish keeps an eye out for predators and has a special tail signal that lets the shrimp know when trouble's coming. At that point, they both hide in the bunker the shrimp dug for them.
When they're out and about, the shrimp uses his antennae sort of like a leash to stay in constant contact with his fish buddy.
I've always preferred the mantis shrimp (not actually shrimp) to the pistol shrimp
so badass looking and they have powerful claws they use to bludgeon or impale prey (depending on the species)
they also produce the same cavitation effect as a byproduct of attacking with their claws
Just fucking insane. God I never want to go into the water again.
the problem is when it gets mentioned they always fail to clarify how incredibly weak the cavitation actually is
it's so tiny and so brief that only advanced equipment can even detect the light that is sometimes produced and the heat that's generated is over such a minute volume that the heat dissipates instantly without any measurable increase in the surrounding temperature
it's really not that big of a deal
Yeah. It's weird, but it doesn't have any noticeable effect. It's an indication of how strong the snaps are, not a contributing cause.
yeah, it's actually the shockwave that results from the collapsing cavitation that stuns/kills prey and even that is only effective within about 5cm and on very small fish
which is still cool, but not nearly as powerful as people act like it is
it's really not nearly as powerful as you're making it out to be
it's extremely localized
yeah, I know it's super small, but doesn't it take a massive amount of strength to even create a tiny little effect like that, or is this no more impressive as an ant lifting 50 times it's own weight?

see, it kind of pisses me off when people act so amazed that an ant can lift 50 times it's own weight
it's a simple matter of scale, it's much much easier for something that small to lift something proportionately larger than something say the size of an elephant to even lift something twice its weight
so ants aren't super strong, that's just how physics work and it would be rather surprising if something that small with an exoskeleton couldn't lift stuff roughly that much heavier than it is

Yeah I agree, but is this the same thing?
I guess in the sense that it's not really all that surprising considering the scale involved

What's going on here? Since when can tigers swim like that?
Also, the idea of shrimp domesticating fish is amusing and a little scary.
i snorkled a bit in aruba and it was just amazing, i didn't want to leave the water
i wanna snorkle again
I want to head back to the Caribbean, but it's not looking like that will happen anytime soon. Though I think my next tropical country I will visit will be Costa Rica.

What is it that's so hilarious about animals bonking into glass walls
and I'm not saying this in a "Shame on you, it may have hurt itself!" way
it's just damn funny
because animals are dumb and us humans laugh at those less fortunate than ourselves. the thumbs up is really th biggest insult to the animal kingdom ever.

haha stupid lower life forms, you haven't even figured out glass yet

I mean seriously, God. That seems unnecessary.
The chambered nautilus is my favorite sea creature, because it swims backwards, by blowing really hard.
I thought this was the scariest image ever but then I found this:
Maximize!!

Go to Grand Cayman and swim along the wall... So amazing.
Coral on T.V. looks cool but it is something completely different to snorkel on a reef yourself.

It's CUTE! I want one!
One time my cat ran into the screen door
just BONK and a sharp bounce back
time to get a new fur coat, mine's all dirty.
