Etymology: Platygillellus: Greek, platys = flat + Theodore Nicolas Gill (1837-1914) researcher of abyssal fishes and systematics (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Écologie
marin démersal; profondeur 0 - 20 m (Ref. 28023). Tropical
Eastern Pacific: endemic to the Galapagos Islands.
Length at first maturity / Taille / Poids / Âge
Maturity: Lm ?, range 4 - ? cm
Max length : 6.2 cm SL mâle / non sexé; (Ref. 28023)
Prefers shallow waters where the sediment size is tiny, especially intertidal areas that have white coral sand. Never found in waters that are brackish or fresh. Carnivores, which prey on a variety of benthic invertebrate animals (Ref. 28023).
