Identification Tips
Body Shape
Its exceptionally slender and elongated body is the most defining characteristic, making it easily distinguishable from most other wrasses.
Coloration
While variable, the mottled green/brown/reddish hues often help it camouflage within seagrass or algal beds. Look for the potential dark lateral stripe.
Behavior
Often observed slowly cruising through vegetation or hovering near the substrate, occasionally darting to pick at prey. They bury themselves in sand at night.
Habitat
- Water type
- saltwater
- Depth
- Typically found in shallow waters from 1 to 30 meters (3 to 100 feet), occasionally deeper.
- Environment
- Prefers areas with dense seagrass beds, algal flats, rubble zones, and sandy patches adjacent to coral reefs. Often found among branching corals or hiding within vegetation.
- Geographic range
- Widespread throughout the Indo-Pacific region, from the Red Sea and East Africa across to the Hawaiian Islands, and from southern Japan down to Australia and New Caledonia.

Key Facts
Master of Disguisebehavior
The Cigar Wrasse is renowned for its remarkable ability to change color rapidly to match its surroundings, providing excellent camouflage among seagrass and algae.
Nocturnal Burrowerbehavior
At night, or when threatened, Cheilio inermis will dive headfirst into the sand or rubble, burying itself completely to sleep or hide.
Unique Genusevolution
Cheilio inermis is the sole species within its genus, Cheilio, highlighting its distinct evolutionary path within the wrasse family.
Dietary Generalistbehavior
Despite its specialized appearance, the Cigar Wrasse is an opportunistic carnivore, feeding on a wide variety of small invertebrates including crustaceans, mollusks, and echinoderms.
Safety Information

- Venomous: No
- Edibility: edible
- Handling notes: No specific handling precautions are required beyond standard fish handling practices to avoid injury to the fish or yourself. They do not possess venomous spines.
Similar Species
Bird Wrasse
Gomphosus varius
While also elongated, the Bird Wrasse has a distinctively long, pointed snout resembling a bird's beak, which the Cigar Wrasse lacks. Coloration also differs significantly, with males being bright green and females mottled brown/white.
Razor Wrasse
Iniistius spp.
Razor Wrasses are also sand-dwelling and can be elongated, but they possess a very compressed body profile and a sharp, blade-like forehead, allowing them to 'cut' into the sand. The Cigar Wrasse has a more cylindrical body.
