A small Japanese puffer fish is the creator of one of the most spectacular animal-made structures. To impress the female puffer fish, the male labors 24 hours a day for a week to create a pattern in the sand. If the female finds his work satisfactory, she allows him to fertilize her eggs. She then lays them in the middle of the circle, leaving the male to guard the eggs alone.

Animals may use florescence for may different reasons.

This bream may use it’s fluorescence to camouflage itself among coral, as it is just as intense as the coral behind it.

The lined seahorse may use it for camouflage or for their elaborate mating rituals.

In sharks it may be used to distinguish between male and female sharks.

The video for this is pretty neat, if you have about 15 minutes of spare time, I highly recommend watching it.

man yells at fish

BEAUTIFUL 💙

I’m on my third watch through and tears are streaming down my face. You must turn the sound on.

*uncontrollable sobbing laughter*

it just keeps getting funnier

The pinnacle is when he points angrily at the fish and doesn’t say anything. You just really FEEL the frustration

Those are grouper. Not sure what kind, but they have big mouths, are solid muscle, and are fairly smart. That guy should probably go spearfish somewhere else, he’s gonna keep losing fish otherwise.

baby fish hiding under the bell of a jellyfish and using its stinging threads as protection from circling predators. this “floating safe house” will provide the fish with protection and food until they’re big enough to venture out on their own. (source)

Those “leaves” around it in the third gif are fish as well! Cornetfish (not a typo, not cometfish) imitate strips of seaweed in order to avoid predators. 

There aren’t any stinging cells up under the jellyfish’s bell, so they hide under there, which keeps predators from spotting and eating them. I mostly see what look like baby jacks, plus a couple of filefish in that second gif.
