and yes, this is off-topic, but you might also be interested to learn that there are several scientific teams that are actively investigating the evolution and biogeographic history of Africa's handsome "squeaker" catfishes, Synodontus species;

thanks to a reader (see comments thread), this blog entry includes a fascinating video of one member of the genus, the cuckoo catfish, S. multipunctatus -- the only documented catfish-y brood parasite in the world.

isn't the natural world amazing?!
