Role WHAT DOES IT LOOK LIKE?
Peacock blennies have elongated bodies flattened from side to side and reach about 13 centimetres. One long fin follows the back; the tail is rounded.
Blue lines and dots mark a beige, greenish-brown or yellowish body. Behind the eye lies an ocellus, a rounded patch resembling another eye, ringed in blue or pink.
Males have head crests and brighter colours than females. Small eye filaments are short and simple.
WHERE DOES IT LIVE?
They frequent very shallow water among rocks, stones, sand and vegetation. Holes and empty shells provide shelters.
They also tolerate brackish water, mixed with fresh water, and very salty water. Salinity is therefore not uniform across the habitats they occupy.
WHAT DOES IT EAT?
They eat small crustaceans, particularly amphipods, and gastropods, molluscs such as sea snails. Algae supplement this diet.
Other small animals, worms and fish eggs are eaten too. Feeding is particularly active early in the morning and in the evening.
