Marine wonders! Spotlight on the grey triggerfish nicknamed ‘donkey’ by the Maltese
Although it seems harmless, the fish can deal out some fair bites too – so keep a respectful distance!
The Cirkewwa Marine Park has shared some information and footage on a charming creature called the ‘Grey triggerfish’ or the amusing ‘Hmar’ in Maltese, meaning ‘donkey’, due to its protruding front teeth!
Its English name, on the other hand, makes reference to the dorsal fin that it raises as a defence from predators when under attack, and which can also be used as an anchor mechanism when it wishes to remain fixed in small spaces.
The grey triggerfish’s habitats usually consist of reefs, harbours and wrecks, at depths up to 100m below sea level, and has a tendency of disturbing sand in an area to expose its prey, which includes sea urchins.
This fish is propelled forward by the undulation of their fins, which while producing an entrancing effect, doesn’t provide much power for their motion, making them relatively poor swimmers.
The marine park reminds divers and snorkellers to take caution with all marine life, particularly during nest building season, when creatures tend to be more protective.
