Removal of spines, hot water soaks Sea urchin injuries are caused by contact with sea urchins , and are characterized by puncture wounds inflicted by the animal's brittle, fragile spines. [ 1 ] : 431 Injuries usually occur when swimmers, divers, surfers, or fishers by accidentally touching them or stepping on them.
Skin contact with this sea urchin should be avoided. An injury caused by the secondary spines should first be soaked in hot water to deactivate the toxins and later vinegar may help soften the spines. Surgical removal of spine tips that remain in the skin is difficult because of their fragility.
The tube feet protrude through pairs of pores in the test, and are operated by a water vascular system; this works through hydraulic pressure, allowing the sea urchin to pump water into and out of the tube feet. During locomotion, the tube feet are assisted by the spines which can be used for pushing the body along or to lift the test off the ...

For marine scientists, it was deja vu: Another die-off swept through the region in the 1980s and slashed sea urchin populations by around 98%. Mystery solved: Scientists ID Caribbean sea urchin killer
It has pentameric symmetry, which is visible in the five paired rows of podia (tube feet) that run from the anus to the mouth. The size is calculated as the diameter of the test (the body not including the spines). This is a relatively fast growing sea urchin, and its age is generally calculable based on its size: one year for every 10 mm. [4]
Sea star pedicellariae may be located on the test's surface or mounted on flexible stalks. Depending on the species, pedicellariae may be surrounding the spines, on the surface of the animal's body, in pits on the abactinal, marginal, or actinal surface, and/or within the adambulacral plate adjacent to the tube foot furrow.
