Goby are fish that often inhabit burrows. Sometimes, these burrows are also home to shrimp. The shrimp and the goby live together as best friends and its the most adorable thing ever.

Moray eels are powerful predators that lurk in the darkness, waiting to pounce on unsuspecting fish and tear them apart. Their large size and hunting habits make them seem imposing, up until you get a good look at them and see how goofy their faces are.





:byodood:

They are actually super shy and only attack people out of either self-defense or clumsy mistakes. Some have even shown extreme affection towards divers they encounter regularly, coming out of their burrows to swim and play with them. A bunch of misunderstood goof balls.

They are derpy all the goddamn time and have a sympatric (?) relationship with seabirds because they sun themselves on the surface and birds eat worms out of their skin. :3:

The word you're looking for is mutualistic. Mutalism is when two species have a relationship where both parties benefit. In this case, the sunfish is cleaned of parasites while the birds get a meal.

Which reminds me of another cool fish, the cleaner wrasse!





These little guys also perform cleaning duties for tons of fish. Huge predatory fish will let the cleaner wrasse swim through their mouth and gills unharmed. The benefit of having the wrasse pick out parasites is so important that these fish have learned to let them go unharmed. The relationship works so well that its completely ingrained in the wrasse's instinct. The cleaner wrasse will even try to clean a divers mouth if they open it at one of their cleaning stations.

Stuff that eats via suction terrify me because they just swallow everything whole and alive.



Jellies aren't fish though, so here's a goofy fish; the tripod fish.



Tripod fish live on the deep sea floor. 3 of their fins have grown extremely long to the point where they aren't very good for swimming. Instead, it uses the fins like stilts and walks along the ground most of the time. They usually just stand around doing nothing, waiting for food to come drifting through the current to them. They just wait to feel something bump up against their fins and then flick it into their mouths.

Deep sea fish are really bizarre and amazing. Its such a different world down there that the hunting and survival strategies employed and have led to all sorts of weird looking creatures





Gulper eels have a body that is almost entirely mouth and stomach. Their jaws are massive and can stretch out even further. Their tiny bodies can expand to accommodate creatures larger than it is. These features allow it to consume prey that would ordinarily be far too big. Their teeth are tiny and only useful on smaller creatures, so anything else they come across is swallowed whole. All of this makes them rather horrifying to me, but they are remarkable creatures. A lot about them still isn't known due to how difficult it is to observe them in their natural environment.
