Blennies
Family Blennidae
updated Oct 08

if you learn only 3 things about them ...
Some can give a nasty bite!
They lay their eggs in empty shells, so please put them back where you found them.
Some of them nibble on bigger living fishes!

Where seen? Small fang-blennies are sometimes encountered on some of our Southern shores, among seagrasses. Divers probably see a greater variety of blennies.

What are blennies?
Blennies belong to the Family Blennidae. From FishBase: the family has 53 genera and 345 species. They are found in the Indian, Atlantic and Pacific Oceans mainly in tropical and subtropical marine habitats.

Features: Most blennies are small, 10-15cm or smaller. They are generally elongated fishes. They lack scales and have a slimy skin. 'Blennos' means 'mucus-like' in Greek. Most have a continuous dorsal fin along the body length and are thus somewhat eel-like. Head usually blunt with short tentacles on eyes, nose opening. As a group, they come in a wide variety of shapes, colours and patterns.

What do they eat? Most blennies are bottom feeders, nibbling on small animals, algae and detritus. Others eat plankton. Some blennies, however, take on larger animals, and specialise in chomping a mouthfull of scales and fins of bigger fish! To get close to their 'prey', these blennies often mimic cleaner fishes.

Fearsome little fishes: A group of blennies called the Sabre-toothed or fang-blennies have small mouths but large teeth on their lower jaws which are mainly used for defence. Some have a venomous bite! Another group of blennies are called Combtoothed blennies which have blunt heads, a wide mouth and comb-like teeth. Some blennies are territorial and can be aggressive even towards large animals.

Blenny babies: Males attract females to lay their eggs in a small hole or crevice, on or underneath empty bivalve shells, or in empty tubeworm holes. The eggs are then guarded by the male or by both parents.

Status and threats: None of our blennies are listed among the threatened animals of Singapore. However, like other creatures of the intertidal zone, they are affected by human activities such as reclamation and pollution.
