Glaucostegus younholeei, the Bangladeshi guitarfish, is a type of guitarfish of the family Glaucostegidae found in the northern Bay of Bengal, Bangladesh.[2][1] This species is recorded from 13 specimens discovered in a fish landing center in Cox's Bazar.[2] It is currently witnessing a population decline of more than 80 percent due to high exploitation rate.[1][2]
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.[2] The maximum length of this species is only around 93cm (37in).[2]
Habitat and distribution
This guitarfish possibly inhabits shallow coastal and continental shelf waters of less than 120 m (394 ft).[2] The specific geographic distribution range can not fully determined since it has only been recorded from one landing site in Bangladesh.[2][1] However, there are some presumptions that Bangladeshi guitarfish may be more wide-ranging and live in the adjacent areas, including Andaman Sea and Strait of Malacca.[2]
Giant guitarfish, especially the smaller species (including the Bangladeshi guitarfish), is locally captured for international fin and meat trade.[1]
