peracarida

OMG!! This tanaid -tiny clawed crustaceans- is one of the cutest I’ve seen on my entire life!! Called Macrolabru maui, is the first pagurapseuid species for New Zealand, it was discovered this year by Scientists at NIWA

Tanaids are related to hoppers and slaters, but are only distant cousing to the hermit crabs in the crustacean family tree. They have this conchicolid (shell-loving) specialisation,  this family is called Pagurapseudidae (something like false hermit crabs).

From Tokomaru Bay, on the Northern New Zealand, this species has adapted to living in micro mollusc with shells less than 5 mm diameters so they are actually pretty tiny creatures, easily missed by people looking for them at the beach
