Шаблон:Short description Шаблон:Speciesbox

Enoplochiton echinatus is a Southeast Pacific species of edible chiton, a marine polyplacophoran mollusc in the family Chitonidae, the typical chitons.[1]

Description

Enoplochiton echinatus is a very large chiton, with specimen confirmed at length of up to Шаблон:Cvt. In Chile, the largest individuals are in the north and the smallest in the south.[2] The species is very dark reddish-brown. The plated shell, which often is covered in epibionts like algae, Scurria limpets and Mytilus mussels, has many spines. These spines are generally up to Шаблон:Cvt long in large individuals, but can be even longer if not broken, which however is unusual. The similar-sized Enoplochiton niger of the same region lacks the spines.[3]

Distribution, habitat and behavior

The distribution of Enoplochiton echinatus ranges along the Pacific coast of South America from Concepción Province (Punta Tumbes) in Chile to Talara in Peru.[3] Although there are old claimed records of this species from the Galápagos Islands, these are considered incorrect.[2]

It lives at depths of Шаблон:Cvt in the intertidal and shallow subtidal zones,[3] with the vast majority of individuals found in the lower intertidal zone.[2] It inhabits rocky coasts in areas that often have heavy surf. Its habitat often has giant kelp Lessonia nigrescens.[3] It is generally quite common, with average densities in appropriate habitat typically being from about 1.5 individuals per square meter to 2.5 per square meter.[2]

The species is omnivorous, feeding on a wide range of algae and invertebrates. It has radular teeth that are quite large, allowing it to eat heavily incrusted things like coralline algae.[2]

Human use

Enoplochiton echinatus is edible and is one of the few commercially important chitons in its range, others being the somewhat smaller, up to Шаблон:Cvt, dark bluish-gray Chiton magnificus and the much smaller, up to Шаблон:Cvt, brownish Chiton granosus. Neither of these have large spines.[3]
