The black long-spined urchin is a sea urchin with very long, hollow spines. It lives on coral reefs, sand flats and seagrass beds across the Indo-Pacific, and it is one of the most widespread sea urchins in that region. Its spines can deliver a mild venom, so it is best to watch where you put your feet.1

Black, near-spherical body (test) with extremely long, narrow, hollow spines, often black but sometimes brown-banded1
Five white spots on the body, which separate it from other Diadema species1
A bright orange ring around the periproctal cone (the 'anal cone'), which is often mistaken for an eye1
Bluish spots on the genital plates and a line of blue spots along the body1
Adults are no more than 70 mm across the body and about 40 mm high1

Koʻpincha adashtiriladi: Other Diadema species are similar in shape and spines, but they lack the five white spots that mark this species. Its orange ring and blue spots also help to tell it apart.1

Uning zahari (chaqsa yoki nish ursa) nima qiladi?

The spines are hollow and contain a mild venom. The toxin mostly causes swelling and pain, which spreads gradually over several hours. The venom is not fatal to humans. The spines themselves are a bigger problem, because they are brittle and needle-like, break off in flesh and are difficult to remove.1

The venom is only mild, and the species is not considered a serious threat to humans. Stepping on it can cause painful stings.1

Qoʻrqqanda nima qiladi?

When threatened by a sudden impact or by spines snapping, it rapidly flips its body over and 'runs' on the tips of its longest spines.1
