acacia tree so they get a nice safe place for

plant has to use valuable resources to

create the gall.

parasitism

Anemone & Anemone Fish

mutualism

This fish lives its entire adult life among the

tentacles of a sea anemone. Anemone fish do not get stung by the anemone as would most

other fish so they get protection from

predators. The fish often drop food scraps which the anemones can eat.

What symbiotic relationship is this?

Boxer Crab & Anemones

This Boxer Crab carries a pair of stinging

anemones in its claws, which it uses to defend itself from predators. The anemones get to move around which increases their food

supply.

partner, and the sea cucumber doesn't seem to

mind.

Goby and Alpheid Shrimp

What symbiotic relationship is this?

mutualism

This alpheid shrimp (onthe right) uses its strong claws like a bulldozer to create a burrow in the

sand. The shrimp is nearly blind. It relies upon its partner, the sharp-eyed goby, to

warn of danger. When a potential predator approaches, both animals disappear

quickly into the burrow

Hawk and Mouse

Birds of prey hunt for small rodents, fish and reptiles high above ground. They have very keen eye sight which allows them to see the small prey scampering through the grass or water.
