Taxonomy
Stenorhynchus seticornis was
Description
The body of S. seticornis is triangular, and the rostrum is drawn out into a long point with serrate edges.[3] The legs are also long and thin, up to 10 cm (3.9 in) across,[4] and the animal's carapace may be up to 6 cm (2.4 in) long.[5] 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.[5] This species presents as diagnostic features: triangular body with long pointed snout (rostrum), carapace decorated with fine dark lines and claws often have violet tips. S. seticornis is most commonly associated with anemones, in groups ranging from one to six individuals in south-eastern Brazil.[6]
Distribution
Stenorhynchus seticornis is commonly found in the shallow sub-tidal on rock bottoms, corals, calcareous algae, and also on soft sediments, such as shelly gravel and sand. Its geographical distribution is restricted to the Occidental Atlantic, from North Carolina to Argentina.[7] Stenorhynchus seticornis is found in the western Atlantic Ocean, from North Carolina and Bermuda to Brazil, including throughout the Caribbean Sea,.[5] It lives on coral reefs at depths of 10–30 feet (3.0–9.1 m).[8]

Life cycle and reproduction
During
Breeding period
Climate majorly regulates the breeding period of the arrow crab. Seasonal variation of water temperature and sunlight duration are considered as the most important variables determining the breeding period of arrow crabs.[16]
There is a positive relationship between fecundity and the size of the parental female.[7] In fact, the size of the female is the key variable in determining the number of eggs per batch. The female also determines the reproductive output of arrow crabs.[17]
Larval stage
Larvae that have grown in shallow water differ from larvae that grow in deeper water. The key difference is in the setation of the endopodite of the maxilla.[18]
