The international demand for high-quality gonads of this echinoderm has led to an extensive exploitation and decline of its natural populations. Consequently, a more thorough understanding of L.

This species is native to the coasts of Chile and Peru and is considered among the key benthic herbivores in Chilean coastal waters. It is harvested commercially by fishermen and is considered an ingredient in Chilean cuisine. They can grow up to mm in diameter or more. It takes eight years for Chilean sea urchins to reach commercial size. The industrial catches and over-exploitation of the animal for canned gonads has caused the extinction of many local populations.
Distribution and habitats: The Chilean sea urchins have a wide geographic distribution along the Pacific coast running from northern Peru to Tierra del Fuego. The highest abundances and the commercial fisheries for Chilean sea urchin are in depth range of m depth in Chile; their preference is for shallower habitats m depth buried in fine sand and muddy sand, beaches.
Feeding Habits: This species is herbivore that feeds -during day and night- on nearby algal pieces. Sea urchin juvenile consume significantly more benthic than floating algae pieces; kelp and other seaweed species which are their preferred food.
When found in deeper habitats, sea urchins may feed on encrusting algae, benthic microalgae, and small invertebrates. In aquaculture, this animal feeds on prepared extruded feeds.
