If the goby finds a piece of food too big for it to eat, it brings it back to the crab, which tears it apart with its claws.

Crabs are messy eaters, and the goby gets some of the scraps.

Still another goby lives near a giant clam.

If the fish spots danger, it darts into the clam's shell. The clam snaps its shell shut, protecting itself and the goby.

After a while, the clam opens its shell a little. If the coast is clear, the goby swims out.

TENDING THE FLOCK.

Thousands of meat ants live together in underground nests.

During the day the ants leave their nest ...

... to tend flocks of baby leafhoppers, or nymphs.

As the nymphs feed on plant juices, the ants protect the baby leafhoppers from predators.

The ants stroke the nymphs' abdomens with their antennae.

In response, the nymphs excrete a drop of sweet liquid called honeydew, which is the ants' main source of food.

YOU CAN FOOL ALL OF THE ANTS SOME OF THE TIME ...

A large, brilliantly colored blue butterfly lays its eggs on a plant growing in a meadow.

The egg hatches into a caterpillar, which begins to eat the leaves of the plant.

Then the caterpillar does a strange thing. It lets go of the plant and drops to the ground.

The meadow floor is a dangerous place for a caterpillar. There are ants and other predatory insects everywhere.
