Environment: milieu / climate zone / depth range / distribution range
Benthic; depth range 0 - 4 m (Ref. 2022). Tropical
Western Central Atlantic: USA, Colombia, Bermuda, Mexico, Venezuela and the West Indies.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 7.6 cm TL male/unsexed; (Ref. 281)
Valve color: Dull grayish green or greenish brown; Some valves, dark-brown arrow-shaped patch on the dorsal ridge. Lateral areas: Five irregular, radiating cords. Central areas: Smooth at the top and eight to nine strong, wavy, longitudinal ribs on the sides. Girdle color: Alternating zones of whitish, green or black.

Epibiotic (Ref. 110502). Very common under rocks, in the zone between tides (Ref. 292); intertidal to shallow subtidal (Ref. 289); intertidal and spray zones of rocky shores (Ref. 2022). Members of the class Polyplacophora are mostly gonochoric. Life cycle: Eggs hatch into lecitotrophic planktonic trocophore larvae (no veliger stage) which later metamorphose and settle on the bottom as young adults (Ref. 833).
