Ecology
Benthic; depth range 0 - 20 m (Ref. 349). Tropical
Western Pacific.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 3.5 cm SHL male/unsexed; (Ref. 349); common length : 2.5 cm SHL male/unsexed; (Ref. 349)
Shell is small and discoidal, similar to Umbonium elegans but the surface is sculptured with fine concentric grooves. The umbilicus is smaller and less inflated and the color may vary but is mainly dark greenish-grey with yellow streaks and pink sutures.
