Echinoderms display morphological and behavioural phenotypic plasticity in response to their trophic environment. [PDF]
PLoS ONE, 2012 The trophic interactions of sea urchins are known to be the agents of phase shifts in benthic marine habitats such as tropical and temperate reefs. In temperate reefs, the grazing activity of sea urchins has been responsible for the destruction of kelp ...
