Urchin Searchin’: Red urchins and drift kelp found at 284 m in the mesophotic zone
Red sea urchins (Mesocentrotus franciscanus) are kelp-associated ecosystem engineers found in rocky habitats throughout the North Pacific from Baja California, Mexico, to Japan.

Echinoderms display morphological and behavioural phenotypic plasticity in response to their trophic environment. [PDF]
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 ...

The energetic link in the benthic community is based on physiological characteristics of the low food absorption efficiency of sea urchins. Low food absorption efficiency of sea urchins is correlated with the activity of digestive enzymes and the ...

Behavioral plasticity of nocturnal marine organisms under interspecific competitive pressure
Pacific abalone (Haliotis discus hannai) are typical nocturnal organisms in the marine benthic ecosystem. However, whether their rhythmic behavior is related to the avoidance of interspecific competition for food resources is unknown.

Conspecific alarm cues crushed from Mesocentrotus nudus prevent sea urchins from foraging the kelp, but do not repel them far away from the kelp. However, it remains largely unknown of whether this phenomenon was affected by conspecific alarm cues or by ...

Sea urchin utilisation in Eastern Indonesia
Sea urchins have long been an important component of gleaning invertebrate fisheries and are valued for their highly nutritious gonads. Sea urchin fisheries are often unreported and unregulated, despite increasing indications of overexploitation. Data on

Eutacticity in Sea Urchin Evolution [PDF]
An eutactic star, in a n-dimensional space, is a set of N vectors which can be viewed as the projection of N orthogonal vectors in a N-dimensional space. By adequately associating a star of vectors to a particular sea urchin we propose that a measure of the eutacticity of the star constitutes a measure of the regularity of the sea urchin. Then we study

Variation in purple sea urchin (Strongylocentrotus purpuratus) morphological traits in relation to resource availability [PDF]
Flexible resource investment is a risk sensitive reproductive strategy where individuals trade resources spent on reproduction for basic metabolic maintenance and survival.
