PASADENA, Calif.—All animals seem to have ways of exchanging information—monkeys vocalize complex messages, ants create scent trails to food, and fireflies light up their bellies to attract mates. Yet, despite the fact that nematodes, or roundworms, are among the most abundant animals on the planet, little is known about the way they network. Now, research led by California Institute of Technology (Caltech) biologists has shown that a wide range of nematodes communicate using a recently discovered class of chemical cues.

Nematode Courting Caught On Camera

Academics / General Science : Science Daily (5 years ago)

Researchers studying the nervous control of nematode mating behavior have produced video footage of a male worm preparing to mate with a hermaphrodite. Researchers investigated the role of the excitatory neurotransmitter acetylcholi... Read Post

'Killer sperm' prevents mating between worm species

Academics / General Science : Science Daily (yesterday)

Most cross-species mating is merely unsuccessful in producing offspring. However, when researchers mated Caenorhabditis worms of different species, they found that the lifespan of the female worms and their number of progeny were dr... Read Post

Males more considerate than imagined -- at least, in nematode worms

Academics / General Science : Science Daily (4 years ago)

Male worms plug females after copulation as a form of 'gift', rather than to prevent them from mating again, as had previously been thought. Researchers found that plugged females mated just as often and were just as attractive as t... Read Post
