Fish Creates Fish

A Philippine anglerfish, looking for all the world like a rock or shell, waves before its maw a piece of bait resembling small fish found in this region. The bait, which is part of the anglerfish's body, has fins, a tail, and black spots for eyes. The waving about of the bait attracts predatory fish close enough for the anglerfish to snap them up. The authors surmise that the anglerfish evolved this realistic bait (and rod and reel) in order to save energy in acquiring food.

Comment. One wonders how many unfishlike baits were evolved before just the right shape and coloration were achieved.

Quotes

  • "Before opening the book, I set certain standards that a volume which treads into dangerous grounds grounds like this must meet. The author scrupulously met, or even exceeded those standards. Each phenomenon is exhaustively documented, with references to scientific journals [..] and extensive quotations" -- "Book Review: The moon and planets: a catalog of astronomical anomalies", The Sourcebook Project, 1985., Corliss, W.
