Goniodoridella savignyi Pruvot-Fol, 1933

Longhorn pump dorid

Philippines · Indo Pacific - South China Sea

Size
⁦3–5⁩ mm
Native range
Red Sea (type locality Gulf of Suez); records further east need confirmation, though Australian specimens match the type

Description

A minute goniodoridid described from the Gulf of Suez in the northern Red Sea. Recent integrative work (Paz-Sedano et al. 2023) showed that the name had been applied to a complex of several externally similar species.

Identification

Translucent white body, 3–5 mm, with yellow restricted to the dorsal tubercles (in three rows), lateral papillae, rhinophores, gill leaves and foot tip. Mantle edge slightly raised; a low ridge runs along the midline from the rhinophores to the gill. Lateral papillae elongate and broader than the gill leaves.

Similar species

G. geminae and G. unidonta are nearly identical externally (G. geminae is opaque white with one yellow crest); identification usually relies on anatomy and DNA.

Habitat & diet

Habitat

Shallow reefs and rubble.

Food

Not documented; like other Goniodoridella, presumably bryozoans.
