Taxonomy and etymology
editFilhollianassa filholi as was originally described by Alphonse Milne-Edwards as Callianassa filholi A. Milne-Edwards,1879.[5] It was named after Henri Filhol, who collected specimens of it from Stewart Island, New Zealand.[5]
Description
editFilhollianassa filholi live in an underground burrow in sand. The shrimp has flap-like abdominal appendages called pleopod which it uses for swimming and creating water movement through its burrow. It has the ability to turn somersaults while moving through its tunnels. It uses its wide tail fan for stabilisation within the burrow. The male has two claws of which one is noticeably larger than the other. Fertilised eggs, yellow in colour, are carried by the female on her abdomen. [4]
