Yesterday’s [21 November 2005] post about squid had a most unsatisfying conclusion, so I feel compelled to mention two things: squidblog has a brief explanation of squid jet propulsion, and I’ve dug up another older paper on squid movement. Even better, it’s about squid nuptial dances and mating.

Photo of a large male escorting a female squid (Loligo vulgaris reynaudii) as she attaches an “egg finger” of about 100 eggs to an egg bed.
