2.4 Remarks
Halimede
genus currently includes four species (Ng et al
.
, 2008).
Halimede tyche
can be distinguished from its
congeners by the ill-defined regions of the carapace (versus well-defined) (Miers, 1884; Galil, 2000).
2.5 Habitat
Muddy or sandy- muddy coast, into 20-30 m deep. (Dai and Yang, 1991)
2.6 Distribution
Northern coast of Australia, China (Guangxi, Hainan, Hong Kong), the Philippines, Indonesia (Dai and Yang,
1991; Davie, 2002), Red Sea and now for the first time from Iraqi coast.
