OCEAN LIFE

SHARKS• Sharks are fish, and they breathe using gills.

Water enters through their mouths and passes through the gills, where the oxygen is removed. Then the water leaves through the gill slits.

CRABS• A crab has a heavy outer skeleton covering

its body. The crab’s body is flat so that it can easily squeeze under and between rocks.

JELLYFISH • Jelly Fish are not actually fish. They are

invertebrates with a jelly-like body, and are related to corals and sea anemones.

• DID YOU KNOW…….. Each year, more people are killed by jellyfish than by the more feared Great White Sharks.

SEALS• Seals are marine mammals with flippers

instead of arms and legs. Although seals live in water, they breathe air and have to return to land to give birth.

SEA LIONS

• Sea lions swim in the shallow water close to the shore above the continental shelf. They like to pull themselves out of the water and lie on sandy beaches.

• Sharks, such as this hammerhead shark, are found in both shallow and deep water. Some sharks can dive down several thousand metres to the bottom of the oceans.

HUMPBACK WHALE

• Whales, such as these Humpback Whales, have to come to the surface to breathe. Most whales swim near the surface of the ocean, and dive deeper to find food.

SQUID• Squid swim through the water by pushing a

jet of water out of their body. They catch krill using their long tentacles. Their sharp beaks rip the krill into small pieces for swallowing.
