The food preferences of macroinvertebrate herbivores for seaweeds containing high DMSP concentrations vary enormously among herbivore species. When temperate green and purple sea urchins Strongylocentrotus droebachiensis and S. purpuratus)... [Pg.183]

The aquatic species chosen was Strongylocentrotus purpuratus, the purple sea urchin. This animal is a common resident of the California coast, a frequent pest in commercial kelp culture, and a specialty food item of growing interest. Phylogenetically, these echinoderms are considered to be in the invertebrate class most directly linked to the vertebrates. [Pg.224]

Seaweed is the favorite food of the purple sea urchin (Arbacia punctulata), whose body is covered in 1-inch (2.5-cm) purple spines. During low tide, sea urchins use their tough spines to carve out holes in the rocks. Once inside their caves, they are protected from desiccation during low tide as... [Pg.79]

The quinones are widely distributed in nature, and about 1200 different quinones have been observed in bacteria, in all plant phyla except mosses, and in animal phyla like echinoderms (sea urchin) and arthropods (insects) (53,54). They may occur in all parts of a plant however, a large propcntion are present in roots, heartwood and bark. The quinones range in color from yellow, through red, purple to almost black. They make relatively little contribution to color in higher plants their color is perhaps most conspicuous in some fungi, lichen, and insects (Coccidae). [Pg.740]
