Thai Name | ชื่อสามัญภาษาไทย: กุ้งก้ามกราม (Kûng k̂āmkrām)
Local Hokkien: Tua Thau Heh

Main Identification Features: Carapace large and hard. Rostum very long. Rostral basal crest low. Tip of telson reaches distinctly beyond the posterior spines of the telson. Several dark blue areas visible near margins of abdomen segments, telson and uropods. Pleural condyle of 4th to 6th segments with dark orange markings. Chelipeds are generally blue but the second chelipeds can be orange. Adult male has very long second chelipeds in which all segments are elongate and have blunt spines.
Size: Males can reach up to 320 mm in total body length, females can grow up to 250 mm.
Habitat and Ecology: Found in turbid water that is directly or indirectly connected with the sea. Larvae require brackish water to survive. Larvae feeds continuously, principally on zooplankton, worms, and the larval stages of other aquatic invertebrates. After larval stage they migrate upstream into freshwater. Become omnivorous, feeding on aquatic insects and their larvae, algae, nuts, grain, seeds, fruits, molluscs, crustaceans, fish, and the offal of fish and other animals.
Remarks: This particular species (M. dacqueti) occurs in Asian mainland from Pakistan, India, Sri Lanka, southern China, Peninsular Malaysia, Borneo and Java island.
