特徴

産地:T. curvirostris is widely distributed across the Indo-West Pacific, from East Africa and the Red Sea to Japan and Australia. It has also entered the Mediterranean Sea as a Lessepsian migrant, through the Suez Canal. It lives at depths of 10–300 metres (33–984 ft) over sandy or muddy bottoms.
In China, it is distributed in almost all coasts of the country, mainly in Wehai and Yantai water areas. And Weihai yields the most production. East China Sea, Yellow Sea and Bohai Sea also have quite large quantities of southern rough shrimps.
特徴:Trachysalambria curvirostris is a small prawn, with males reaching a total length of up to 81 millimetres, and females reaching 105 mm. The exoskeleton is "densely pubescent" (covered in thick down). The rostrum is straight or slightly curved upwards, and bears 7–11 teeth on the dorsal (upper) side. The last four segments of the pleon have a median crest, while the second segment has a tubercle on the mid-line.
T. curvirostris can be distinguished from similar species that occur in the same areas (such as Megokris sedili and Megokris granulosus) by the form of the petasma and thelycum (male and female reproductive structures), and by the colouration of the uropods; these are red or reddish brown, with conspicuous white margins in T. curvirostris, but yellowish with grey or brown margins and centre in M. sedili, and red or reddish brown with golden margins in M. granulosus.
