Fishing

How do you know if a fish is sleeping? It’s pretty easy to tell when fish are sleeping: they lie motionless, often at the bottom or near the surface of the water. They are slow to respond to things going on around them, or may not respond at all (see some sleeping catfish here). If you watch their gills, you’ll notice they’re breathing very slowly.

Why do fish not have tongues? Yes, most fish do have tongues, but they aren’t at all like ours. Most fish have a bony structure called the basihyal on the floor of the mouth that superficially resembles a tongue. But it doesn’t have taste buds, isn’t muscular and has very little range of motion, so it isn’t directly equivalent.

This man captured one of his koi eating a garter snake.

What will eat the fish poop? There is no fish that will eat poop in an aquarium. Occasionally fish are seen chewing on fish poop, but that is because they mistake it for food. Even catfish, plecos, or shrimp do not eat fish poop. The only way to remove fish poop is to use a gravel vacuum and remove it manually.

Are jellyfish aware they are alive? Jellyfish sting for the same reason many sharks bite, they bump into something they think might be food and try and eat it. Are jellyfish conscious? Jellyfish have no brains and therefore are not aware of their own existence.

Do jellyfish have brains or hearts? Lacking brains, blood, or even hearts, jellyfish are pretty simple critters. They are composed of three layers: an outer layer, called the epidermis; a middle layer made of a thick, elastic, jelly-like substance called mesoglea; and an inner layer, called the gastrodermis.
