Sea Urchins: Biology and you will Ecology
Connolly (1986) features registered 8 understood and you will ten putative predators out-of adult and teenager H. erythrogramma in Southern Australian continent. Of them, Connolly (1986) concluded 1st predator on website he learnt is actually the typical Octopus australis. The guy believed it absolutely was accountable for all of the lifeless tests for the the room because these got drill holes regular away from octopus predation. Andrew (1999) detailed that sea-star Coscinasterias calamaria is an important predator out of water urchins inside the launched habitats. Shepherd and you may Clarkson (2001) learned the latest giving decisions of your wrasse Notolabrus tetricus within the South Australian continent. It learned that while you are H. erythrogramma shaped the main diet plan regarding wrasse, instance big fish, it was not a preferred prey item in line with crabs and you may molluscs, such as abalone. In West Australian continent, Get ready and you can Vanderklift (2011) registered four species of seafood (you to definitely fabric-coat (Moncanthidae) and you will five wrasse because the predators regarding H. erythrogramma. Cook and you can Vanderklift (2011) did not discover that West material lobsters (Panulirus cygnus) were essential predators of H. erythrogramma. It has also been verified into the managed experiments from the Dumas ainsi que al. (2013) , who discovered that when you are P. cygnus did consume H. erythrogramma, crab and bivalve victim was in fact considerably well-known over ocean urchins. Read More
