Urchins do have tiny pincers called pedicellariae that cover their body, and although they can deliver a paralyzing toxin to small predators they are too small to pierce human skin.
Q. What do you do if you get stung by a sea urchin?
If you’re stung by a sea urchin, immediately remove any part of the sea urchin that’s embedded within your body. Use tweezers to remove the large spines. You can use a razor to gently scrape out the pedicellariae. Once you do this, wash the affected area with soap and water.

Q. Are black sea urchins poisonous?
Yes. Sea urchins have two types of venomous organs – spines and pedicellaria. Spines produce puncture wounds. Contact with sea urchin spines and their venom may trigger a serious inflammatory reaction and can lead to .
Q. What is the most venomous sea urchin?

Q. Are purple urchins poisonous?
Its first line of defense is its sharp spines, which many divers can tell you are no joke. The next line of defense is the tiny stinging structures found in their spines, called pedicellarines. Pedicellarines are poisonous, and can be released into prey or attacking predators.
Q. What animals eat purple sea urchins?
Sea otters, sunflower stars and California sheephead prey on the purple sea urchin. Sea otter predation on the purple sea urchin helps protect kelp forests from destruction. Sea otters that regularly eat the purple sea urchin are easily detected — their bones and teeth turn sea-urchin purple!
Q. What animal eats sea urchins?

They’re sweet, umami and a little bit salty.
Q. Why do they harvest sea urchins?
When it comes to consumption, sea urchins are harvested for their gonads, also known as uni. These bright yellow to orange lobes are “stockpiles” of sugars, amino acids, and salts: a trifecta of sweet, salty, and umami. It’s been dubbed as the foie gras of the sea given its buttery texture and delicate ocean flavors.
Q. How long do sea urchins live?
– A new study has concluded that the red sea urchin, a small spiny invertebrate that lives in shallow coastal waters, is among the longest living animals on Earth – they can live to be 100 years old, and some may reach 200 years or more in good health with few signs of age.
Q. What eats a sea star?
Many different animals eat sea stars, including fish, sea turtles, snails, crabs, shrimp, otters, birds and even other sea stars. Though the sea star’s skin is hard and bumpy, a predator can eat it whole if its mouth is large enough.
