Spawning and nesting behaviour of Tachypleus gigas along the East coast of Peninsular Malaysia

Present study was aimed to address the spawning and nesting behaviour of Malaysian horseshoe crab (Tachypleus gigas) in observed nesting grounds of East coast of Peninsular Malaysia during monsoonal period. Field sampling was carried out in every full and new moon days between September and December...
