In the present study, we demonstrate the presence of the high-affinity choline transporter in sea urchin
embryos and larvae, the development of the transporter over the period in which this organism uses ACh as a trophic signal, anomalies associated with inhibition of choline transport, and proof that these adverse effects are related to inhibition of ACh synthesis, rather than other aspects of choline availability.
Next day Luke waded into the sea at Mombasa without flippers - and stood on a sea urchin
which left 60 three-inch spines in his foot.

We examined the bacterial community compositions in cultured sea urchin

The sea urchin
Diadema antillarum, an inhabitant of Caribbean coral reefs, uses crevice shelters and often aggregates with conspecifics for protection against predators, which appears to reflect a conflicting balance between group defense versus competition for limited shelter.
