Byzenus scaber Rafinesque, 1814 Stenopus spinosus is a shrimp-like decapod crustacean belonging to the infraorder Stenopodidea.

Stenopus spinosus can grow up to 8 centimetres (3.1 in) long, and is chiefly yellow, with white antennae and white tips to the chelae (claws).

[3] Stenopus spinosus is commonly found in shallow waters in the Mediterranean Sea, and at greater depths in adjacent parts of the Atlantic Ocean.

[3] It is frequently encountered on night dives in parts of its range.

[4] A record of S. spinosus from the Red Sea proved to be a different species, Engystenopus spinulatus.
