Fish

what do the dorsal and anal fins do for a fish

This is called the operculum

One reason might be the 'false economy' of having to heat up their bodies. Approximately 80% of human energy goes towards heating our bodies to a stable temperature. However, for fish and reptiles to do this, it may not have been a evolutionary advantage. For example snakes and crocodiles can gorge themselves on one large meal and then not have to feed again for months. This would not be possible if they had a 'central heating system'. Likewise fish would need to devote large amounts of energy towards heating up their bodies in colder water and it makes sense for them to merely adapt to it instead. An example of this is the fact that although fish are exothermic, many species are capable of surviving in large temperature variations (so long as they are not too rapid) that would quickly kill most mammals. Therefore although mammals are warm blooded, they are far less tolerant of changes in temperature that deviate too far from whatever their species ideal is.

i like cheese

An angler fish has a lure on its head that glows. There are more, but what they are called, I know now!

Yes and no, while all sharks that I know of eat some kind of meat, they don't all eat the kind you'd expect. I have heard of a shark that eats only plankton much like whales.
No, the whale shark, the basking shark and the megamouth shark are filter feeders and feed on phytoplankton.

It simply means you're out of your 'comfort zone'. We all have places and situations that we're content with - whether that's a job we've done for a number of years, or a town we've lived in for a long time. Taking someone into a new situation or place - would be like taking a fish out of water - a totally alien concept.

The general term for a young fish is a fingerling.

All fish belong to the kingdom Animalia and the taxonomic domain of Eukarya, which are characterised by having cells with nuclei. Eukarya covers all organisms in the Kingdom Animalia, as well as the Kingdoms Plantae, Fungi and Protista.

Fish may bite other fish as a form of competition for territory or resources, establishing hierarchy within the group, or in defense against perceived threats. These behaviors can vary depending on the species of fish and their social structure.

They exhale through the mouth.

The blob fish was discovered in the 1800s and can be found in the Pacific ocean

No. Fish are one of the five families of vertebrates (animals with backbones) that include fish, reptiles, amphibians, birds and mammals.

Fish are similar to reptiles being cold blooded, they lay eggs, and have scales, but are different from reptiles as fish breathe through gills and live exclusively underwater, whereas reptiles breathe through lungs on land. Fish lay eggs that have thin membranes (skins) in water. Reptiles usually lay eggs with thick leathery skins on land.------------------------------------------------------------------------------------------BUT,fish pretty much evoled to make reptiles.so if you look at it,reptiles are like land living fish!both have scales and most lay eggs...

hope my answer helped! :)

It is best that all fish have a filter besides Betta fish. Betta fish don't need filters cause the filter pushes them over with their big fins. Goldfish should have a filter on there tank because they are often overfed. If you have a filter you won't have to change the water as often. The only fish that shouldn't have a filer in captivity are Betta fish.

All fish are Ectotherm which means they rely primarily on outside sources of heat to maintain proper temperature, however, there are a few species who can produce slightly higher amounts of heat, either to specific points of the body or it's entirety to aid in hunting or digesting.
Not all fish are cold-blooded. Some fish are warm-blooded such as sharks, tuna and swordfish. As the temperatures in the water changes, the body temperatures of the fish will change also.
Yes,because they live in water and they are not mammals

I have been told they smoke quite nicely.... but please observe fire restrictions if smoking in the open

bony fish have backbones

You have to fillet the fish and throw away all the small bones.

They blow air bubbles which may mean a sign of lack of air or they may be pregnant and are making a nest for the eggs.

it is dangerous to other fish because it is poisonion

yes I am pretty shure. Yep! I go to Boka Chica for vaca sometimes and i caught a puffer there but it was by itself. They mad easy to catch with just looking down into the water with a net, they are suuuuuuper slow.

jelly fishes has no bones nd they are realll 99% or 100% made out of water

yes there spreading over united states of America they have reached New York,illonois and more states.

Rabbits, bunnies

No, they swallow it from the bottom of the ocean, then once it goes through their digestive system, they poop it out.

Vinegar is a very dilute form of acetic acid. In quantities and dilutions found in the home, vinegar is not harmful, nor is it flammable. Vinegar has many healthy and beneficial uses.

Highly concentrated acetic acid is corrosive and flammable.
