The Bangladeshi guitarfish (Glaucostegus younholeei) is a type of guitarfish of the family Glaucostegidae found in the northern Bay of Bengal, Bangladesh.[1][2] This species is recorded from 13 specimens discovered in a fish landing center in Cox's Bazar.[1] It is currently witnessing a population decline of more than 80 percent due to high exploitation rate.[2][1]
Description
The Bangladeshi guitarfish can be differentiated from its congeners from these characteristics: long and narrow blunt pointed snout, broad oblique nostrils with the narrow anterior opening, brownish or greyish body color with a narrow wedge-shaped disc, cranium margin sharply demarcated before eyes, rostral ridges almost joined along their entire length, relatively longer tail.[1] The maximum length of this species is only around 93 cm.[1]
Habitat and Distribution
This guitarfish possibly inhabits shallow coastal and continental shelf waters of less than 120 m (394 ft).[1] The specific geographic distribution range can not fully determined since it has only been recorded from one landing site in Bangladesh.[1][2] However, there are some presumptions that Bangladeshi guitarfish may be more wide-ranging and live in the adjacent areas, including Andaman Sea and Malacca Strait.[1]
Giant guitarfish, especially the smaller species (including the Bangladeshi guitarfish), is locally captured for international fin and meat trade.[2]
