Eunephrops cadenasi is a medium-sized lobster with a cylindrical body.

Adult male individuals of Eunephrops cadenasi reach a total length of 30 centimetres (12 in), and a carapace length of 5–14 cm (2.0–5.5 in), while females only reach a carapace length of 4–5 cm (1.6–2.0 in).

[2] The natural range of Eunephrops cadenasi extends from the seas off the Bahamas and Dominica southwards to Jamaica and Colombia.

[2] Eunephrops cadenasi was named by Fenner A. Chace Jr. in 1939; the type locality was at a depth of 300–315 fathoms (1,800–1,890 ft; 549–576 m) at "Nicholas Channel south of Cay Sal Bank" (23°21′N 79°58′W / 23.350°N 79.967°W / 23.350; -79.967),[2] north of the island of Cuba.

The specific epithet cadenasi commemorates José Manuel Cadenas y Aguilera, Rector of the University of Havana.
