Diet
The bluemarked drombus is a carnivorous bottom-dweller that mainly feeds on small animals, such as crustaceans and worms.[5]
Size and appearance
The bluemarked drombus has a robust and compressed body with a large head. The caudal fin is long and pointed in the middle and it has ctenoid scales covering the body all the way until the beginning of the first dorsal fin. The head has no scales at all.[6] It usually reaches around 5-6 centimetres.
Conservation status
The bluemarked drombus is given the status of Least Concern by the IUCN Red List. However, it faces several threats, including the development of housing and urban areas and domestic and urban waste water pollution.[1]
