General Facts - Part 2

Most fish reproduce with the female laying eggs and the male fertilising them.

Newly hatched fish are called ‘fry’.

Great white sharks are one exception to this rule however - they actually give birth to live young, which are known as pups.

It is common for fish to change sex (both from male to female and from female to male) as part of their reproductive process.

Relative to their body size, fish actually have quite small brains compared to other animals.

Fish are divided into three main groups: cartilaginous (whose body-frames are cartilage not bone), bony and lobe-finned (such as lungfish and coelacanths).

The oldest known goldfish ever was called Goldie and lived to be 45 years old!

The whale shark lays the largest eggs of any animal; in the 1950s one was found that was more than 35cm long!

The first public aquarium was opened in London in 1853.

fish are the most popular pets today in the United States, with around 12 million households owning aquariums.
