Marine Fish and Aquatic Creatures

Marine fish are divided into three groups, herbivores, carnivores and omnivores, each requiring different types of food.

Marine fish drink water through their gills and saltwater fish do actively drink sea water.

Fish can drown in water if they don't have a consistent intake of oxygen.

Sharks are the only fish that have eyelids and they can't move them.

Blacktip female sharks are capable of self-reproduction.

The blue streak cleaner wrasse changes sex from female to male.

Most Wrasse bury themselves in the sand at night to sleep and can also perform this behaviour when threatened or startled.

The most poisonous fish in the world is the Stone fish.

Seahorses are the only fish that swim upright.

A baby seahorse is called a “fry” and they are tiny replicas of the parents.

Jellyfish and starfish are not fish at all and belong to a group of species called invertebrates.
