Symbiotic Relationships

Barnacle/Whale

Barnacles create home sites by attaching themselves to whales. As the barnacle is a filter feeder, it also gets access to more water (and more food) due to the relationship. Whale is unaffected.

Cuckoo/Warbler

A cuckoo lays its eggs in the nest of the warbler. The cuckoo’s eggs hatch first and the young kick the warbler eggs out of the nest. The warbler raises the cuckoo babies and the warbler babies aren’t hatched.

Ostrich/Gazelle

Ostriches and gazelles feed next to each other. They both watch for predators. Because the visual abilities of the two species are different, they can each identify threats that the other animal may not see as readily.
