The world hotspot for crayfish species, by a long, long way, is the southeastern United States (map from Richman et al. 2015).

The southeastern U.S. is also notable for relatively large populations of African-Americans.

You might think that given the overlap in these two maps, that there would be expertise in the African-American community about crayfish. But I am struggling to think of any African-American scientist who has studied crayfish. Who am I missing?

This also points to crayfish being a great entry point to introduce African-Americans to topics like biology and conservation.
