Heterozius rotundifrons big hand crab , is a species of crab of the family Belliidae , endemic to New Zealand . The carapace width is up to 25 millimetres (1 in ).
Behavior [ edit ]
When threatened, Heterozius rotundifrons has a unique antipredator behavior where it fully extends all its limbs including its chelipeds and becomes immobile. The crab keeps defensive stance for up to a few minutes.
