1- Stenopus hispidus(banded coral shrimp)
Stenopus is a of marine decapod crustaceans comprising eleven described , commonly known as boxer or coral shrimps. Members are characterized by enlarged, asymmetrical chelipeds used in defense and intraspecific combat. Several species, particularly Stenopus hispidus, are significant in the ornamental aquarium trade and function as cleaner organisms in reef . The genus exhibits monogamous social structures and prominent agonistic mediated by dopamine and neuroendocrine .

Habitat
Marine subtidal environments, primarily coral reefs and rocky substrates. Depth range extends from shallow waters to mesophotic zones; Stenopus devaneyi has been documented at 60 meters depth at Mayotte Island. occupy crevices and caves within reef structures.
Distribution
Indo-West-Pacific region, with extensions into the Atlantic. Stenopus hispidus and Stenopus spinosus confirmed in Brazilian waters at 27°S. Stenopus devaneyi reported from Mayotte Island in the Western Indian Ocean.
Behavior
Exhibits prominent agonistic when encountering conspecifics of the same sex, involving tactile contact via and antennules. Agonistic interactions are mediated by dopamine, , octopamine, and glutamate, with dopamine and acetylcholine playing primary roles—a distinct pattern from the serotonin-based aggression regulation observed in most other pan-crustaceans. Monogamous social structure. Stenopus hispidus establishes cleaning stations visited by reef fishes and hawksbill turtles (Eretmochelys imbricata).
Ecological Role
Cleaner in coral reef ; removes and debris from client fishes and marine turtles. Serves as for parasitic isopods including Argeiopsis inhacae, which causes in females.
Human Relevance
Highly valued in the ornamental aquarium trade, particularly Stenopus hispidus. Collection from wild threatens reef and has prompted development of captive breeding protocols. Serves as a non-insect model organism for studying neuroendocrine regulation of agonistic in arthropods.
