Nuttallochiton mirandus is a medium to large-sized species of polyplacophoran mollusc in the family Mopaliidae.[1][2] It was initially described by the zoologist Johannes Thiele in 1906[1][1][2] and is endemic to Antartica's cold waters.[2][3]
Description
[edit]Nuttallochiton mirandus is medium to large in size, measuring about 38 mm (1.5 in) long. It has a creamy white shell, sometimes stained reddish brow which is very elevated and appears saw-toothed in lateral view. It has high, brittle valves with a notch in the center. Each valve consists of 8 to 10 strong ribs, crossed by fine growth marks. This chiton has a leathery and wide girdle which is covered with fine and elongate spicules.[2]
Distribution and habitat
[edit]Nuttallochiton mirandus is a common circumpolar chiton which is endemic to Antartica's cold waters.[3][2] It can be found from only 30 metres (100 ft) deep to the depth of 1,400 metres (4,590 ft) and mostly thrives on hard bottoms.[2]
Feeding
[edit]Nuttallochiton mirandus is a grazer which mainly feeds on Bryozoans and foraminifera. It uses its radula to swallow big pieces of bryozoan colonies.[2]
Reproduction
[edit]To reproduce, both males and females of this species bend the posterior part of their body and release eggs and milt respectively in the water column.[2]
