Acropomatiformes
Acropomatiformes is an order of fish in the sub-class Actinopterygii, the ray-finned fishes. It is a relatively small order, containing only two families, the Acropomatidae (commonly called “lantern-eyes”) and the Pseudochromidae (commonly called “dottybacks”).
Common Names
The common names for the families within Acropomatiformes are "lantern-eyes" (Acropomatidae) and "dottybacks" (Pseudochromidae). These names reflect the characteristic features of these fish.
Characteristics
Members of Acropomatiformes share a number of key characteristics, including:
- Elongated body shape: Both families have a generally elongated, fusiform (torpedo-shaped) body.
- Large eyes: The name "lantern-eyes" refers to the large, prominent eyes of Acropomatidae, which are often situated high on the head.
- Small mouth: The mouth is typically small and located at the front of the snout.
- Scales: The scales are ctenoid, meaning they have small spines or teeth.
- Dorsal fin: The dorsal fin is continuous and has a single, shallow notch.
- Anal fin: The anal fin is generally short and has two spines.
Environments
Acropomatiformes are primarily found in marine environments, with the majority inhabiting coral reefs, rocky reefs, and seagrass meadows in tropical and subtropical waters. They are often found in relatively shallow waters, although some species may venture into deeper regions.
