Nemo, the title character from the Disney-Pixar film 'Finding Nemo', is a fictional clownfish. Clownfish are small and brightly-colored reef fish commonly found in the Pacific and Indian Oceans. They are known for their orange bodies with white stripes, which make them instantly recognizable. Clownfish are also notable for their symbiotic relationship with sea anemones, in which they live among the venomous creatures' tentacles without being harmed.
