Here's an unusual approach to ensuring the survival of a species! Introduce young biologists to the California grunion, a fish that mates on land rather than in the water. The video shows how grunion make use of time and the tide to leave their little ones high and dry, as well as the frys' eye view and their escape from their sandy nursery.
