Environment:  benthic; brackish; marine
Distribution:  Western Pacific.
Diagnosis:  The horseshoe crab body is divided into three parts: the front dome-shaped prosoma, the middle marginally-spined opisthosoma, and the rear spike-like telson. The width of the prosoma is commonly in estimating the age and growth stages since it can be measured easily and yields the smalles errors in measurement (Ref. 127127).
Biology:  Found in sandy and muddy shores (Refs. 127122, 65878). Occurs from low and high tide mark; often found at spring low tide (Ref. 1131) in mangrove swamps (Ref. 70). Breeds on sand patches at high tide (Ref. 68). Inhabits shallow intertidal pools dominated by Halophila beccarii. Juveniles burrow at low tide (Ref. 65787.
IUCN Red List Status: Endangered (EN); Date assessed: 22 July 2018 (A4bcd) Ref. 123251)
