This four-inch-long (10-centimeter-long) fish shares an amazing partnership with another sea creature: the anemone . The partnership benefits both participants, and the close relationship led to the fish being named an anemonefish.
The female anemonefish passes over the nest site several times. Each time she swims over it she releases eggs—in the end they number from 100 to more than 1,000. The male follows her closely and fertilizes the eggs. It can take more than two hours for this whole process to be completed.
