Evolution turned this fish into a 'penis with a heart.' Here's how.

"For many anglerfish species, the male's sole responsibility is to permanently latch onto an obliging mate, fuse his circulatory system with hers, then slowly allow his eyes, fins and most of his internal organs to degenerate until he becomes what biologist Stephen Jay Gould called "a penis with a heart." The male gets constant nourishment; the female gets sperm on demand. The anglerfish circle of life spins on."

"...so how does a female anglerfish's body accept a male's (or, in some cases, up to eight simultaneous males) so willingly? A genetic study published July 30 in the journal Science finally offers an answer: Anglerfish mating is only possible because the fish have somehow evolved away some of their most crucial immune defenses."
