Berthella martensi
(Pilsbry, 1896)
 
Berthella martensi
Maximum size:  ( )

Identification:  This species is highly variable in color but all forms have lines or creases surrounding the central portion of the notum and demarcating three major lateral areas of the mantle.

Natural history:  On Lanai and Oahu, Berthella martensi is a rare species found in exposed rocky habitats at 5-15 m (16-50 ft). However, it is noticeably more common on the Big Island. When disturbed, it can autotomize portions of its mantle with the breaks occurring along the characteristic creases.

Distribution:  Big Island, Lanai and Oahu: widely distributed in the Indo-Pacific; also in the eastern Pacific.

Taxonomic notes:  It was first recorded in Hawaii at Puako, Big Island by Scott Johnson on Aug. 12, 1980 and is illustrated in Johnson, 1982 as "Berthella species 1".
