Acentronura
Acentronura is a genus of marine fish in the family Syngnathidae, commonly known as pipefishes. These fishes are distinguished by their elongated, tubular bodies and the absence of pelvic fins. They are found in tropical and subtropical waters around the world, primarily in coral reefs and seagrass beds.
Common Names
Members of the genus Acentronura are commonly known as pipefishes, specifically dwarf pipefishes. Some species have additional common names, such as the "pygmy pipefish" for Acentronura gracilissima.
Characteristics
Acentronura species share a number of common characteristics:
- Elongated, tubular body: This body shape is characteristic of pipefishes and helps them to maneuver through seagrass and coral.
- Absence of pelvic fins: Unlike most fish, pipefishes lack pelvic fins, contributing to their slender appearance.
- Small size: Acentronura species are generally small, with most species reaching a maximum length of less than 10 centimeters.
- Dorsal fin: They possess a single dorsal fin located towards the rear of their body.
- Snout: The snout is elongated and often slightly curved, allowing them to reach into crevices for food.
- Coloration: Acentronura species exhibit a variety of colors and patterns, often blending in with their environment.
Environment
Acentronura species inhabit a range of marine environments, but are most commonly found in:
- Coral reefs: These fishes are well adapted to the complex structures of coral reefs, using their elongated bodies to navigate through crevices and overhangs.
- Seagrass beds: They are often found among seagrass, where they can camouflage themselves and find food.
- Rocky shores: Some species can be found in rocky intertidal areas.
