🔬 Taxonomy

🐟 Physical Description

Dorsal spines (total): 3; Dorsal soft rays (total): 27 - 30; Anal spines: 0; Anal soft rays: 25 - 27. The characteristic scythe mark crossing the pectoral base is yellowish-tan to green in juveniles and subadults. : short and / or deep.

🌀 Behaviour

They are usually solitary creatures, but it isn’t uncommon for them to travel in pairs. In rarer circumstances, they can be seen swimming in trios. They generally inhabit shallow and warm waters of the tropics and subtropics. When these fish aren’t feeding, they patrol and hover around the reef, especially near areas that greatly vary in depth and topography in order to have easy access to a hiding spot from predators. Sufflamen bursa, like their relatives, are carnivorous and secondary consumers. Their diet includes shrimps, sea urchins, worms, crabs, smaller fish, and other invertebrates. They don’t eat coral but instead will prey upon and pick at clams and other animals that attach themselves to live rocks or corals This behavioral trait helps to mitigate populations such as rock-boring creatures like sea urchins when there is an overabundance in a certain population of a species that they feed upon. They don’t seclude themselves from picking off crustaceans and mollusks from rocks. They will actively seek out prey such as smaller fish. They also flip sea urchins upside down to access their soft bellies which are defended with significantly less spines. Since they are consumers, they are also susceptible to parasites and diseases.
