    We see many animals every day, but we would be worried if we saw any of these animals on our way to school!

Walking sharks

In 2006, scientists found a new kind of shark off the coast of Indonesia. It can “walk” with its fins along the coral reefs. These walking sharks are about 1 to 1. 2 metres long. They eat shrimp, crabs and small fish. If they are surprised by something, they can swim away using their fins.

The platypus

The platypus is found along the rivers and lakes of eastern Australia. It lays eggs like a bird, has webbed feet like a frog, a bill like a duck and is as poisonous as a snake! We are pleased to hear that it spends much of its life underground.

An unusual dolphin

In 2006, a Japanese fisherman caught an unusual dolphin. It has an extra set of fins near its tail, about the size of human hands. Scientists say that its extra fins could be the remains of back legs. This may be proof that dolphins once lived on land. Evidence from fossils tells us that dolphins were once four-footed land animals. Scientists believe that as they spent more and mor time in the water, their back legs slowly disappeared.
