🌀 Behaviour

Behavioural data for Saddle wrasse is currently being reviewed.

🦐 Diet

Saddle wrasses are carnivores and opportunistic feeders, consuming anything that will become available to them. As juveniles, they will tend to be considered "cleaners'': such as picking parasites from larger fish or animals, but as they mature they will start to scavenge for worms, shells, mollusks, shrimps, and other crustaceans. They have canine teeth and pharyngeal bones near their gills in order to help crush the shells.
