Acanthostracion
Acanthostracion is a genus of boxfish found in tropical and subtropical waters worldwide. These fish are known for their distinctive bony plates that cover their bodies, giving them a box-like appearance. The genus belongs to the family Ostraciidae and is closely related to other boxfish species.
Common Names
Acanthostracion species are commonly referred to as "boxfish" or "trunkfish" due to their box-like bodies. Specific species may have additional names, such as the "scrawled cowfish" (Acanthostracion quadricornis) and the "yellow boxfish" (Acanthostracion polygonius).
Characteristics
Members of the genus Acanthostracion share several key characteristics:
- Bony Plates: Their bodies are covered in hexagonal bony plates that are fused together, forming a rigid shell. These plates provide protection from predators and can be used for defense.
- Small Mouth: They have small mouths with tooth-like plates that allow them to feed on algae, sponges, and invertebrates.
- Dorsal Fin: A single dorsal fin is present towards the rear of the body.
- Caudal Fin: A tail fin (caudal fin) is used for propulsion.
- Ventral Fins: Two pectoral fins are located on the sides of the body.
- Coloration: Acanthostracion species often exhibit vibrant colors and patterns, which can vary depending on the species and geographic location.
- Size: These fish typically reach a length of 15-30 centimeters (6-12 inches) depending on the species.
Environments
Acanthostracion species are primarily found in tropical and subtropical waters, inhabiting coral reefs, rocky shores, seagrass beds, and mangroves. They prefer clear, shallow waters with plenty of hiding places and food sources.
