About Chilomycterus antennatus (Cuvier, 1816)
Scientific Naming and Size
Chilomycterus antennatus, scientifically named by Cuvier in 1816, reaches a maximum total length of 38 cm.
Spine Characteristics
The species has 10 to 12 short, fixed spines covered with fleshy sheaths across its head and body. These spines are arranged in an approximate row running from the snout to the dorsal fin, and spines on the top and sides of the body stand more vertically erect.
Distinctive External Features
Chilomycterus antennatus also has long tentacles positioned above its eyes, and small black spots covering its head and body.
Inflation Ability
Like all species in the family Diodontidae, C. antennatus can inflate its body by swallowing water or air. This inflation ability, combined with the species' spines, provides protection against most predators.
Habitat and Depth Range
This fish lives on or near coral reefs and seagrass beds, at depths ranging from 2 to 13 meters.
