Yes. Just like we would if we died in water
Their corpses become bloated with decomposition gases and this causes them to float, much like a balloon would. And because muscle mass is much denser in a fish's back, this tends to turn the fish upside down.
If they are on their side, yes. It is unusual for a fish to just float to the top of the water and stay there for awhile. It is their instinct to keep swimming around more towards the bottom of the water, unless food is thrown onto the top of the water.
no,snais dont float when they die. they just lay there and get rotten!
Freshwater snails will certainly eat dead fish, as will a variety of marine snails. There are predatory snails called cone snails that live in the pacific that hunt, kill and eat fish like any other type of predator. They have a type of venemous harpoon that they are able to launch into fish. This paralyses the fish instantly and then the snail eats it.
floating like fish
no!
Sounds like a dead or dying fish. Could be swim-bladder, extreme stress, or a gas build up.
Aquatic snails breathe through a gill. Very similar to how a fish breathes. Terrestrial snails have a lung and breathe like you or I.
No. Fish have back bones (like us). Squid are molluscs (like octopuses, snails, oysters, etc.)
A fish has to be alive in order to prevent it from sinking, When it dies the water pushes it down just like everything else that is at the bottom of your aquarium. They have no air in them so they won't float.
they look dead! lol
snails mostly live on vegetables like lettuce.
Yes, octopi are fond of crab and lobster as well as other crustaceans, echinoderms, snails, fish, and such. They shred and consume these with powerful beak-like mouthparts located where their tentacles converge.
no, Fish like all animals breathe in Oxygen and out Carbon Dioxide.
Crabs are predators and scavengers. They will eat just about any dead creature, although they prefer live prey. They eat mollusks like snails and small fish when they can catch them.
