Creatures of the Deep

I've been toying with the idea of getting a deep-sea creature tattoo and ordered the book Creatures of the Deep for inspiration.

Its wonderful book chucked full of bizarre sciencey-goodness. Here's an excerpt:

In some anglerfish species, the male becomes a lifelong "parasite" of its prospective mate. The males jaws and skin around its mouth fuse with the female's body, leaving only a small space at the sides of the mouth for gas exchange. In time, the male's circulatory system becomes connected to the females and his internal organs and eyes degenerate. The female becomes the sole bread-winner, and the male, in essence, becomes a sort of non-retractable penis. It may not seem much of a life for the male either-but it neatly solves the problem of find one's mate in the dark depths.
