Etymology: Anisotremus: Greek, anisos = unequal + Greek, trema, -atos = hole (Ref. 45335). More on author: Bloch.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 0 - 20 m (Ref. 9710), usually 0 - 15 m (Ref. 40849). Subtropical; 31°N - 35°S, 98°W - 28°W
Western Atlantic: Florida, USA and the Bahamas through the Gulf of Mexico and the Caribbean Sea to Brazil.
