Black Bullhead Tornado-Underwater Video

After the eggs hatch, thousands of black bullhead are guarded diligently by the male parent. Predation reduces their numbers, and by fall only a handful remain. No longer under the protection of their parents, survivors from multiple nests begin to reform in large schools in shallow water, as a new year class of fish is created.  At first the schools can be small, consisting only of the survivors from any given nest. But eventually, by early fall, each nest has merged with others creating giants schools that can number in the thousands.

In this unique, HD underwater video, you'll go below the surface to see black bullhead fry navigate the underwater landscape in their first year of life.
