Identification
Hyaline white body about 3 mm long, with yellow-orange on the mantle-edge protuberances, mid-dorsal crest, rhinophore tips, gill branches and the papillae. Two small conical papillae in front of the smooth, non-retractile rhinophores; two broad-based, triangular papillae behind the gill, wider than the four simple gill branches.
Similar species
G. geminae has an opaque white body and slender, sausage-shaped posterior papillae; G. savignyi has a different radula. External differences are subtle and DNA or anatomy is often needed.
Habitat & diet
Habitat
Shallow coastal and reef habitats.
Food
Not documented; like other Goniodoridella, presumably bryozoans.
