摘要

本報告記述台灣海域新記錄的一種屬於梭子蟹科（Portunidae）的圓額尖指蟹Caphyra rotundifrons（A. Milne- Edwards）。它不像其它的梭子蟹抖的種類善於游泳，而且都以綠色的帚狀綠毛藻Chlorodesmis fasti-gata（C . Agardh）Ducker為棲所。這種蟹類和藻類密切結合的關係是少見的。本種蟹的生態照片、形態特徵、分佈、以及其棲所藻類在文中皆有記述。

This paper establishes a new record of the turtle-weed crab Caphyra rotundifrons (A. Milne-Edwards, 1869), family Portunidae, collected from Taiwan inshore waters. Unlike other portunid crabs, the turtle-weed crab remains almost permanently ensconced in a tuft of seaweed, Chlorodesmis fastigata (C. Agardh) Ducker (1969). Such an association between crabs and algae is uncommon. Photographs, diagonostic characteristics, distribution, and ecological association with seaweed of C. rotundifrons are provided.
