[edit] Description
.jpg){kind=icon}
The body of S. seticornis is triangular, and the rostrum is drawn out into a long point with serrate edges.[1] The legs are also long and thin, up to 10 cm (3.9 in) across,[2] and the animal's carapace may be up to 6 centimetres (2.4 in) long.[3] Colouration is variable in this species: the body may be golden, yellow or cream, marked with brown, black or iridescent blue lines; the legs are reddish or yellow, and the claws are blue or violet.[3]
[edit] Distribution
Stenorhynchus seticornis is found in the western Atlantic Ocean, from North Carolina and Bermuda to Brazil, including throughout the Caribbean Sea.[3] It lives on coral reefs at depths of 10–30 feet (3.0–9.1 m).[4]
[edit] Ecology and behaviour
S. seticornis is nocturnal and territorial.[5] It eats small feather duster worms and other coral reef invertebrates. [5] They are commonly kept in reef aquariums to control bristle worm population.[6]
[edit] Life cycle
During mating, the male places a spermatophore on the female, which she uses to fertilise her eggs. These fertilised eggs are then carried on the female's pleopods until they are ready to hatch into zoea larvae.[5] These swim towards the ocean surface and feed on plankton. They grow through a series of moults, and eventually metamorphose into the adult form.[5]

Stenorhynchus seticornis was first described by Johann Friedrich Wilhelm Herbst in 1788, under the name Cancer seticornis. It was also described as "Cancer sagittarius" by Johan Christian Fabricius in 1793, a name which is now a junior synonym of S. seticornis.[7] Pierre André Latreille erected the genus Stenorhynchus (originally mis-spelt Stenorynchus) in 1818,[7] and S. seticornis was confirmed as the type species by the International Commission on Zoological Nomenclature in 1966.[8]
