Fish

A collection of fish is called a host.

I'd always heard that a bunch of fish is a school, but perhaps an official collection is called something else. ("School of fish" is one of the clever puns in the movie Nemo. Nemo is not going to be alone, but with others--he's joining the school.)

A baby fish is called a 'fry' when they reach the point they can feed themselves. They are later called 'juveniles' when they have acquired their scales and fins. Once that cycle is complete, they are referred to as 'fingerlings,' which is a reference to their size.

When we go underwater, we have to fill our lungs with air in order to stay under the water. Whales and dolphins also have lungs and also have to resurface in order to spend any length of time under the water. Fish on the other hand don't have lungs and very rarely rise to the top of the water, so just how do they survive?

As you probably already know, fish have gills. The water around the fish produces a tiny amount of oxygen. In order for the fish to be able to stay under the water he needs to be able to take in oxygen. The fish's gills do just this. They filter the oxygen in the water and this enables the fish to be able to breathe in water.

If you take a fish out of the water, it will die of suffocation. This is because the oxygen in the air has not been filtered through its gills and the fish can't breathe it in properly.

When you find your goldfish lying dead on the top of its bowl, it has probably suffocated from a lack of oxygen because they oxygen has been used up by some other means such as bacteria. So always make sure you clean Jaws' bowl out regularly!

The orange-clown anemonefish are prey for a number of fish such as sharks, stingrays, and other larger bony fishes as well as moray eels. While the eggs are susceptible to predators as well. Humans also prove to be the biggest danger because they are captured and taken from the ocean to be sold or kept.

it has denticles

Baby fish are called fry.

Defense mechanisms such as camouflage, spines, and poisons help fish escape predators.

They belong to the bony fish category. See the related link.

The ceolacanth lived about 410 million years ago. That's pretty old. Living specimens have been caught in recent times, but, as individuals it seems that they 'only' live for about 80 to 100 years. Even older fish fossils have been found, but it has been difficult to identify these as being truly fish. The oldest fish in captivity is reckoned to be about 80 years old. Also, other fish have been caught in the wild which appear to be about 100 years old. See Related Links below these three ads.

Because fish are exothermic (meaning they use heat from outside of their body) they will often become more sluggish or lethargic during winter. Other than that, they will try to keep their same habits. And even pond fish will need a more deeper pond to hibernate.

Because it gave them the ability to bite, which is a helpful tool for self-defense and hunting. No dictionary results were found. Please try another search.

cats only have one life. the nine lives are a superstition created by the fact that a cat can jump off a high place without dying

YES or NO ? Do Pangasius hypophthalmus fish have scales ?

No! (and therefore they are not kosher.)

Goldfish dont have to have a filter but they need water conditioner like all fish.Fish can survive without a filter but they are always good to have because you dont have to clean it out as often

Puffer fish are actuall tiny little fish, when they see danger the puff up and they have spikes to protect themselves against predators. They are also very poisonus.

Quite a lot of fish are Hermaphrodites, they can switch their sex as they mature and become breeding stock.

Typically, for all fish they become very large in the belly area in a day and then slowly or rapidly become paler in the shade of whatever color they are. the question of what to do with the babies is under the question what to do with baby algae eaters?

Well, I wouldn't be to happy, I like salmon! Their predators would die out and their prey would thrive. People would have to catch more of other fish so those fish would eventually become extinct... Basically, nothing good. And the worst part is, NO MORE SALMON FOR DINNER!!!! WAAAAAHH

There are three species of the perch: Percaflavescens (Yellow perch), Perca fluviatilis(European perch) and Perca schrenkii (Balkhash perch).

Sharks belong to the Chondrichthyes class which means that they lack what is called "true bone". Their "skeleton" is made up of cartilage, which is the same as the human ear, so they do not have an actual skeleton.

An amberjack is any of several species of large food and game yellowtail fishes of the genus Seriola.

Some of the adaptations that allow fish to live in the water are gills, fins, and scales. The gills allow the fish to live in the water. The gills allow the fish to extract oxygen from the water. The fins allow the fish to swim through the water and help it stear itself. For the scales I'm not sure!

There is not enough Oxygen in the air for the fish to breath. Water has just the right amount of air (O2) that the fish need and in the right proportions.

Fish breath in water with gills. Water is capable to holding within it a very large amount of Oxygen. So it is super-concentrated. But the O2 in our air is far less concentrated then in water, so the fish try to gulp the air through and into their gills, but the gills cannot easily find or absorb the O2 from the regular, unpressurized air.

A marine fish placed in freshwater will likely experience stress and potential health issues due to the drastic change in salinity. The fish may struggle to regulate its internal salt levels, leading to problems with osmoregulation. In severe cases, this can result in the fish becoming weak, vulnerable to disease, and ultimately dying.

Because of the nature if this question, many answers will be highly opinionated. Some people will prefer birds over cats, while others will like cats better than birds. There is no "correct" and sure-fire answer.
