Sea urchins Loxechinus albus were collected from an unfished population inhabiting inshore areas of the eastern part of the Falkland Islands. This chapter discusses the ecology of Loxechinus albus (L. albus) by focusing on the larval ecology, factors that determine spawning, habitat selection. The red sea urchin Loxechinus albus is distributed from Isla Lobos de Afuera in Peru to the southern tip of South America. Loxechinus albus is one of the most.

Saggio sulla Storia Naturale de Cili. Six-eleven ambulacral plates, geminated, each one with a primary tubercle. Numerous large periproctal plates.

Primary spines short in adults, conical: Pedicelaries globiferous with a neck between stem and head, with large valves, variable number of lateral teeth, one-four per side. Hemispherical test, greenish, occasionally with red ambulacres and interambulacres large specimens from deep waters can be white, partially or completely.

Littoral, intertidal and subtidal pools. Up to m in depth Larrain This species feeds both at day and night mostly on drifting algal pieces captured with the aboral pedia. Spawning period occurs later in the year as latitude increases: The specimens reach commercial size after 8 years. The industrial catches for canned gonads has caused the extinction of many local populations.
