More on author: Castelnau.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 3 - 15 m (Ref. 9710). Subtropical; 32°N - 33°S
Western Atlantic: Bermuda and southern Florida (USA) to Brazil; throughout the Caribbean Sea.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 17.5 cm TL male/unsexed; (Ref. 9626)
Adults have a vertically elongate blue spot on each scale, the head has alternating vertical lines of pale blue and brownish orange, but these are broader than on X. novacula; adult males are more green in overall color and have a blue-edged inky black spot on midside of body within a pale region of pink or yellow (Ref. 13442).
Most common in shallow, sandy areas in and around seagrass beds. Prefers clear waters (Ref. 9626). Generally of no interest to fisheries because of its small average size (Ref. 5217).
