About Acroteriobatus variegatus
The Stripenose Guitarfish (Acroteriobatus variegatus)
The stripenose guitarfish, scientifically known as Acroteriobatus variegatus, is a species of ray that is endemic to the eastern coast of India and Sri Lanka. This fish is a resident of the neritic zone, the part of the ocean extending from the low tide mark to the edge of the continental shelf. While specimens have been found at depths as great as 366 meters, they are more commonly observed in shallower waters.
Habitat and Distribution
This species primarily inhabits depths ranging from 10 to 40 meters. There is evidence suggesting a preference for coral reef environments, making these areas crucial for their survival. The stripenose guitarfish's distribution is limited to the coastal waters of India and Sri Lanka.
Physical Characteristics and Reproduction
The stripenose guitarfish is a relatively small species. Males typically reach lengths of up to 65 centimeters, while females can grow slightly larger, up to 75 centimeters. Reproduction involves small litter sizes, with females usually giving birth to between one and six pups. The generation length of the stripenose guitarfish is estimated to be approximately five years.
Conservation Concerns
The population of the stripenose guitarfish is facing a significant decline. The primary threat identified is fishing by trawlers operating along the coasts of India and Sri Lanka, which poses a considerable risk to the species' long-term viability.
