In the waters in and around New Zealand, 77 living species of crabs (and 10 species of crab-like Anomura) have been recorded, along with a further 24 species of fossil crabs (marked with an obelisk). [1] Of the extant crabs, 37 are endemic to New Zealand (marked in boldface). The taxonomy below follows Ng et al. (2008) for the extant species, [2] and De Grave et al. (2009) for the fossils. [3]
Almost all the species are marine, with a single freshwater species, Amarinus lacustris (Hymenosomatidae). [1] An updated checklist published in 2010 lists 167 species of Brachyura, plus a little over 50 species of crab-like Anomura. [4] This list (of N.Z. Decapoda) has been republished with annotations in 2011. [5]
