Dolphins may be smarter than chimpanzees. They have a simple language to communicate with each other and can follow ships through difficult waters, sometimes guiding them. Dolphins are also friendly toward humans. They are mammals that live in the sea, unlike fish.

15. For many years people believe that the cleverest animal
after man were chimpanzees. Ow, however, there is proof
that dolphins may be even smarter than these big apes.
Although a dolphin lives in the sea, it’s not a fish. It is a
mammal. It is in many ways, therefore like a human being.
Dolphins have a simple language. They are able to talk to
dolphins. But this will not be easy because dolphins cannot
hear the kind of sounds made by a third language which the
dolphins can understand.
Dolphins are also very friendly toward man. They often follow
ships. There are many stories of dolphins guiding ships
through difficult and dangerous waters.

24. Take a look at a pet cat’s paws. Now
imagine them at least 10 times bigger—
that’s tiger-sized. A tiger can bring down
it’s prey with a single bat of its paw. First,
it grips with its long, sharp claws. Then, for
a tighter hold, it pulls its claws in. Ouch!

What do crabs
use claws for?
Many crabs have big, blunt claws like
hammers for smashing shellfish. Others use
jagged claws like knives to slice up their
food.
Robber crabs live on land. They climb up
coconut trees. They use their huge claws to
pry open the tasty coconuts.
Sea anemones are underwater animals with
stinging tentacles. Boxer crabs grab a fistful of
them and use them as boxing gloves to punch
animals.
