Clinical Toxicology, 2005
A 25-year-old female was walking along a shallow tropical reef when she felt a sharp pain in her right great toe. Upon exiting the water, she noted multiple dark spines protruding from the foot.

In the sea urchin morphogenesis follows extensive molecular specification. The specification controls the many morphogenetic events and these, in turn, precede patterning steps that establish the larval body plan. To understand how the embryo is built it was necessary to understand those series of molecular steps.

Extreme morphologies are often found in extreme conditions. Many commonalities exist in the morphology of deep and shallow-water sea urchins, but different evolutionary histories and adaptations to living at great depths have created peculiar and divergent morphologies within deep-sea sea urchins.

Cilia are exceptionally complicated subcellular structures involved in swimming and developmental signaling, including induction of left-right asymmetry in larval stages. We summarize the history of research on sea urchin embryonic cilia. The high salt method to isolate cilia is presented first; methods to block cilia formation and to lengthen cilia ...

International Journal of Biochemistry, 1975
Abstract 1. 1. Paramyosin-like protein was extracted and purified from the lantern muscle of sea urchins mostly of Pseudocentrotus depressus . 2. 2. The amino acid composition, the circular dichroism spectrum and the subunit molecular weight of this protein are characteristically similar to those of the known paramyosin, while the ...

Sea urchin granuloma is a chronic focal response to the puncture of sea urchin spines, induced by the permanence of prickle remnants in the wound. Until recent years, it was thought to represent a foreign body reaction but, following the description, in 2001, of its several histologic forms, the spectrum of its likely pathogenetic mechanisms has ...

Sea-urchin stings may produce injurious and venomous wounds. Although numerous writers refer to the danger of pedicellarial stings, there is little worth-while clinical data. We report a case of sea-urchin injury with severe local reaction and acute hepatitis.

Sea urchins (Echinoidea) are found along the Mediterranean and especially the Red Sea coasts of Israel. The most important species are Diadema setosum on the Red Sea coast, and Paracentrus lividus on the Mediterranean. When stepped on, the brittle spines penetrate and the venom they carry causes further damage.
