So called "Fish facts"

Firstly I don't believe all these, but thought I would let you make p your own minds. :D


A father sea catfish keeps the eggs of his young in his mouth until they are ready to hatch. He will not eat until his young are born, which may take several weeks.

A female mackerel lays about 500,000 eggs at one time.


All clams start out as males; some decide to become females at some point in their lives.

An electric eel can produce a shock of up to 650 volts.

Catfish have 100,000 taste buds.

Dolphins sleep at night just below the surface of the water. They frequently rise to the surface for air.(yes I know it’s a mammal).

Goldfish lose their color if they are kept in dim light or are placed in a body of running water, such as a stream.

It takes a lobster approximately seven years to grow to be one pound.

Sharks apparently are the only animals that never get sick. As far as is known, they are immune to every known disease including cancer.

The harmless Whale Shark, holds the title of largest fish, with the record being a 59 footer captured in Thailand in 1919.


The largest Great White Shark ever caught measured 37 feet and weighed 24,000 pounds. It was found in a herring weir in New Brunswick in 1930.

The turbot fish lays approximately 14 million eggs during its lifetime.

Unlike most fish, electric eels cannot get enough oxygen from water. Approximately every five minutes, they must surface to breathe, or they will drown. Unlike most fish, they can swim both backwards and forwards.

The only one i know isnt true is:

"Unlike most fish, electric eels cannot get enough oxygen from water. Approximately every five minutes, they must surface to breathe, or they will drown. Unlike most fish, they can swim both backwards and forwards."

I've watched them for upwards of 30 min at a time and they never surfaced. They might be confusing them with a lungfish. South American lungfish dont use gills to breath at all to breath and can drown after they loose there fry gills.
