Dizzydeani (actually, I believe, Mastagaphora dizzydeani - thanks sid!) is the species name for a particular spider. It was given this somewhat whimsical moniker by a baseball-loving naturalist; the spider hunts by weaving a sticky ball of silk, and hurling it at passing prey. The name is a play on the famous pitcher Dizzy Dean. Trivia: We are aware of perhaps 35,000 species of spider; this naturalist estimates there are something like 135,000 species as yet unobserved or uncategorized.
