**Welcome to the Fishapedia Wiki!**

Welcome to the science information wiki about fish, about news with fish in them, movies about fish or movies that have fish in them, that are like famous fish from movies or are in movies.

Here on this wiki you can read articles, look at images and watch videos to do with fishy stuff, or fish stuff, enjoy exploring the fish wiki.

The staff for this wiki is Anna Cherith McDermott.

She only wants stuff to do with fish on this wiki only, NEVER anything else that is not to do with fish.

**About Fish:**

All fish share two traits: they live in water and they have a backbone—they are vertebrates.

Apart from these similarities, however, many of the species in this group differ markedly from one another.

Fin fish like salmon have gills, are covered in scales, and reproduce by laying eggs.

Eels, by contrast, have worm-like bodies and exceedingly slimy skin.

Lungfish gulp air.

Whale sharks, the largest fish, give birth to live young and eat only tiny fish, squid, and plankton. Some species, such as the weedy sea dragon, are so bizarre they seem almost unreal.

Fish have developed special senses, too.

Because water transmits sounds, disperses chemicals, and conducts electricity better than air, fish rely less on their vision and more on their hearing, taste, and smell.

Many can detect motion in the water using a special row of scales with sensors known as the lateral line.

Others can find their prey and even navigate by detecting electrical charges.

One reason fish are so diverse is that 70 percent of the planet is covered in water.

The animals in this group live in a variety of habitats ranging from coral reefs and kelp forests to rivers, streams, and the open ocean.

Another is that fish are very old on the evolutionary scale.

According to fossil records, they have been on Earth for more than 500 million years!

The total number of living fish species—about 32,000— is greater than the total of all other vertebrate species (amphibians, reptiles, birds, and mammals) combined.

## **Here Are Some Interesting Facts About Fish:**

1. The amazing Spotted Climbing Perch is able to '***gulp'*** oxygen from the air and can crawl over land using its strong pectoral fins in search of water.

2. Catfish have over 27,000 taste buds, whereas humans have only 9,000.

3. What is the loudest fish? The answer is, the croaker.

4. What percentage of a fish's size is made up of brain? Fish typically have quite small brains relative to body size compared with other vertebrates, typically one-fifteenth (0.06 per cent) the brain mass of a similarly sized bird or mammal.

5. Did you know, fish can get sunburn, but it is unusual unless there is something about their environment that does not allow them to seek deeper water or some kind of shelter.

6. Which kind of fish can live in the coldest temperatures? The answer is the Antarctic ice fish, which have antifreeze in their blood, live permanently at -1°C.

7. Is it true that a fish surrounds itself by its snot to protect itself? Yes - parrot-fish produce a mucus "***tent***" that completely covers them.

8. Did you know that fish have a specialised sense organ called their lateral line, which works much like radar and helps them navigate in dark or murky water?

9. It was not until 1853 in London, UK, when aeration and filtration of water was understood, that people were able to keep fish as indoor pets.
