Where
seen? This rather fat and colourful but little wrasse is sometimes
seen on our Northern shores, among coral rubble near seagrasses. Sometimes seen high and dry on sand or stuck inside coral rubble or
sponges. Some seen were very pale, others were more brightly coloured. It was previously known as Halichoeres dussumieri.
Features: To about 16cm, but
those seen are usually about 5-8cm long. Usually colourful: silvery
to greenish with red, yellow and blue markings forming 4-5 broad bars
across the body. Dark spot in the middle of the front
half of the dorsal fin, another spot at the pectoral fin base. Snout pointed, sharp teeth. |

Nasty bite! This little fish can give a nasty bite to a naked hand or finger. It is often seen stranded at low tide and our natural instinct is to pick it up and put into a nearby pool of water. This is when the fish can give a painful nip and take out a chunk of your finger or hand! If you really want to transfer it to a pool of water, do not use bare hands. Or you can just leave it alone, the fish is likely to be able to survive until the tide returns. |
