Sperm whale?

Question

why is a sperm whale called a sperm whale ? does it shoot a mighty load?

Answer 1

"Spermaceti is the semiliquid, waxy substance found in the head of the sperm whale. The name derives from the late Latin sperma ceti (both words actually loaned from Greek) meaning "sperm of the whale" (strictly, "sperm of the sea monster"). The common name for the species is actually an apocopation of Spermaceti Whale. Early whalers mistook the substance for the whale's s***n."

Answer 2

That's why they called him Moby d**k.
