A small puffer with a row of dark blotches along the lower flank and bars on the tail, sitting on sand and rubble.
To about 18 cm, tan with a row of dark blotches along the lower flank and two dark bars across the tail base. It sits on sand, rubble and seagrass rather than hovering, and it relies on being still.
Tetrodotoxin again, and the same point: poisonous rather than venomous, so it is dangerous to eat and harmless to approach. It inflates only as a last resort, and a fish made to do it for a photograph has been put through something costly for a picture of behaviour it does not normally show. This site does not carry photographs taken that way.
Ratings are per location: 1 means found on most dives that look for it, 5 means a handful of records. Where enough dives have been logged the figure is calculated from them; otherwise it is an editorial estimate, and says so. We publish habitat and destination, not the dive site.
