Fish

Bony fish are in the PHYLUM VERTEBRATA

Hagfish are cartilaginous, meaning their skeletons are made from cartilage.

FALSE

what the person just wrote is wrong. Hagfish are neither cartilaginous or bony fish. Although they have cartilage in their bodies, they belong to a third category called Jawless fish. Jawless, cartilaginous, and bony are the 3 types of fish.

The male seahorse is the only known fish species where the male becomes pregnant and carries the embryos until they are born. The female deposits her eggs into the male's brood pouch, where they are fertilized and develop until birth.

fish dont actually sleep; they have no eyelids. scientists dont know for sure but they think that they go into a state of rest.

It can be hard to tell if a fish is sleeping; they might float motionless, float on bottom of tank or hide in tank decor.

A swim bladder gives a fish a abillity to float and sink, They also could store water in it like a birchir.

You go to the breeding room and click breed and then pick 2 fish to breed, then when the fish are done, click lay egg.

Well, it really depends on what kind of fish it is. if it's something like a bass, then it'll probably eat whatever bug or or small fish ( such as a minnow) comes it's way. If it's a goldfish... no

External, as most fish do. The females release millions of eggs, some of which are fertilised by the released clouds of sperm from males that are swimming in tandem with the female. Then the eggs drift with the current for 13-15 hours until the larvae hatch.

I think they do,but you can double check that on google.

Hope that helps.

Fish can fish for fish, because anglerfish can fish for other fish.

Saltwater: redtoothed trigger fish

Freshwater: Jack Dempsey cichlid

Fish are found in the sea because they have evolved over millions of years to live and thrive in aquatic environments. The sea provides fish with food sources, shelter, and the necessary conditions for survival, such as oxygen levels and water temperatures.

I think that the largest fin of a perch is the first dorsal fin, the one that is located on the top of the fish and is spiny.

A crab has evolved to move sideways in response to its environment. Its body is relatively flat with eyes that face forwards on stalks. It lives in rock crevices and moves sideways across the surfaces of coral, etc with its back against the rock face, therefore always facing outwards to possible threats from predators, other crabs, etc. When danger appears it can easily conceal itself in gaps between rocks for protection where necessary. I have seen crabs do this on many occasions as a scuba diver and this explanation seems very reasonable to me.

Ichthyologists are scientists that study fish

Black knife ghost fish may disappear due to stress, illness, water quality issues, lack of hiding spots, or aggression from tank mates. It is important to assess these factors and address any issues to create a suitable environment for your fish.

Seahorses do

A fish breaths through it's gills.

Fish with high levels of mercury, like tuna and swordfish.

Fish, like all other vertebrates, have bones to support their muscles, retain body shape, and protect internal organs. The backbone is very important because it protects the spinal chord which supplies nerve connection throughout the body, and allows the animal to move by keeping its shape.

They generally range from brown to gray to black. Their underside is often white.

They adapt by camoflauging into the rocks!

No, the fishes breathe through their gills.
