Found singly with just their heads showing, in abandoned worm holes, or roaming close to their holes, looking for victims to attack, and then diving into their holes for protection, over surge zones, of lagoons and seaward reefs. They mimic other fish, often changing their colour to get close to passing fish, and then attack biting off small pieces of mucus, scales and tissue. They also like to eat divers!!!!

Combtooth Blennies are the largest family of blennies, found in both tropical and subtropical waters and freshwater habitats, as the name suggests they have comb like teeth lining their jaws.
Sabretooth Blennies have teeth to match their name!
They can be seen darting forward to sever flesh from fishes fins. (can sometimes be seen taking a swipe at divers as well) They will then dart back into their holes out of harm's way.
Some blennies will mimic cleaner wrasses to get close enough for a nip at fish.
A few Sabretooth Blennies are venomous. Ref: https://www.fishbase.se/summary/Plagiotremus-tapeinosoma.html
