Arbacia punctulata

L. rhomboides, S. schlegeli, and S. sordidus and the sea urchins Arbacia punctulata and D. savignyi acutilol A inhibit A. punctulata, L. rhomboids, and S. schlegeli and acutilol B inhibits S. schlegeli (Cronin et al. 1997)... 

Tyrosine-derived metabolites in this section do not include spiro-cyclohexadienyl-isoxazolines and related compounds (Sect. 3.22.3.3) or bastadins (Sect. 3.22.3.4), but they do include tyrosine-derived alkaloids that were covered in the Alkaloids section in the first survey (1). The prolific bryozoan Amathia convoluta, collected in Tasmania, has yielded amathamide G (1953) (1814), the latest of several amath-amide alkaloids from the genus Amathia (1). A Florida collection of this animal furnished the new convolutamines A-E (1954—1958) (1815), F (1959), and G (1960) (1425), and a Tasmanian sample of this bryozoan afforded convolutamine H (1961) (1319). A study of Amathia convoluta from the North Carolina coast has yielded volutamides A-E (1962-1966) (1816). Volutamides B and C reduce feeding by the pinfish (Lagodon rhomboids) and the urchin (Arbacia punctulata), respectively, and volutamides B and D are toxic toward larvae of the hydroid Eudendrium carneum. The New Zealand Amathia wilsoni contains the six novel amathaspiramides A-F (1967-1972) (1817).

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...

The hypnotic barbiturates are capable of causing a fully reversible inhibition of cellular functions in simple organisms. They can, for example, inhibit cell division of fertilised eggs of the sea urchins (Arbacia punctulata), and movement of the larvae of the marine worm Arenicola cristata [160]. The blocking effects occur at or before the eight cell stage, and produce no immediate lethal effects. Complete recovery occurs when the eggs are returned to normal sea water after 2 hours or less, of exposure to the barbiturates.
