SEA ANIMALS

BLUE WHALES .

Blue whales are the biggest animals in the sea and probably the largest animal that ever lived on earth .

A blue whale is a mammal , not a fish , and it has fins instead of legs .

It spends its life in water , but has to come to the surface to breath .

A blue whale can grow to 30 meters long - at least twice as long as a bus .

This gigantic creature leads a quiet life and feed mainly on plankton , particular shrimp , like krill which it filters the water .

It sometimes eats as many as 40 million a day blue whales usually live alone , except for mothers caring for their young .

The blue whale usually swims at about eight kilometers per hour , but can speed up to 32 kilometers .

SAILFISH

marlin and swordfish can move very fast when they hunt in the ocean .

they are easy to recognize as they have a very long upper jaw which looks like a sharp spear .

these fish prey on schools of of small creatures such as sardines .

They swim into a school of fish and slash them with their spear like jaws .

then they gobble up the fish .

these hunters also use their spears to protect themselves against sharks and killer whales .

The speedy blue marline sometimes leaps above the surfice as it swims .

GREAT WHITE .

The mighty great white shark is one  fiercest fish in the sea and it is the biggest hunter .

It grows to more than 4.5 meters long and weighs  more than 4.5 meters long and weighs 2,000 kilograms - more than a rinoshoress .

The huge mouth of a great white is lined with jagged teeth , which can be 7.5 centimeters long .

The shark uses them to attack and kill its prey .

The great white has an extraordinary sense of smell.
