Common name
- Short‑headed blenny (used in some regional field guides)
Physical description
- Small, elongated fish reaching a maximum total length of approximately 7–9 cm.

Habitat
- Shallow, coastal marine environments, especially coral reefs, rocky substrates, and tide pools.
- Typically found at depths of 0–15 m, often among crevices and under ledges.
Behavior and ecology
- Benthic and primarily diurnal; spends much time hovering near the substrate.
- Territorial, with individuals defending small home ranges.
Diet
- Carnivorous; feeds on small benthic invertebrates such as crustaceans (e.g., amphipods, copepods) and polychaete worms.
Reproduction
- Oviparous.
- Eggs are demersal and adhesive, deposited on the substrate.
- Males are known to guard the egg clutch until hatching.
Conservation status
- The species has not been assessed for the IUCN Red List; no major threats have been documented, and it is generally considered to have a stable population in its range.
