Chiton magnificus

provided by wikipedia EN

Chiton magnificus, the liquorice sea cradle, is a Southeast Pacific species of edible chiton, a marine polyplacophoran mollusk in the family Chitonidae, the typical chitons.[1]

Chiton magnificus

Description

Chiton magnificus is a very large chiton, with specimen confirmed at length of up to 17.4 cm (6.9 in). It is shiny and very dark bluish-grey.[2]

Distribution and habitat

The distribution of Chiton magnificus ranges along the Pacific coast of South America from Cape Horn in Chile[3] to San Lorenzo Island in Peru.[2] Although there are old claimed records of this species from the Galápagos Islands, these are now considered incorrect.[2]

This species is found in places with strong current along rocky coasts, including pools.[2] It can be found at depths of 0–31 m (0–102 ft),[4] but in northern Chile it appears to be restricted to subtidal areas.[2]

Human use

Chiton magnificus is edible. Although relatively uncommon, it is one of the few commercially important chitons in its range, others being the even larger, up to 23 cm (9.1 in), spiny Acanthopleura echinata and the smaller, up to 4.5 cm (1.8 in), brownish Chiton granosus.[2][5]

Distribution

provided by Zoosystematics and Evolution
Bullock (1988) gives a distribution for this species from Isla San Lorenzo, Peru south to Bahía Tictoc (43°36’40”S; 72°57’15”W), Chiloé Province, southern Chile. This species can be found in rock pools and boulder fields with strong water exchange, from the intertidal down to a maximum of 30.5 m depth at the Comau Fjord (42°23’S; 72°27’W), Region of Aysén (Schwabe et al. 2006). Smith and Ferreira (1977) considered the records of this species from Galapagos Islands as erroneous.
