About the Cover

Known collectively as Cuban topminnows, the diminutive livebearing fishes of the genus Girardinus are found in the streams, small rivers, and ditches of their native Cuba. This issue’s cover features a metallic topminnow (G. metallicus), a color form known as the blackchin or blackbelly topminnow, which, as Mike Hellweg explains this month, is thought to have been derived from a population from a river in Cuba where the males of the species are almost entirely black.

Tip of the Month:

That mudskippers, those amphibious gobies that scurry around on the shore and climb mangrove roots to get insects, cannot breathe air? They carry water in a pouch around their gills, keeping those organs wet, so they can continue to extract oxygen---sort of "wet-dry gills"!
