Black long-spined urchin
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

No anndirto nde
- 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
Ina jiiɓindiree e: 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

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

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

It can move 760 mm in just 7 seconds by rolling and walking on the tips of its spines.1
It has no eye, but it has a diffuse light-sensing system that lets it detect light levels and the size and colour of objects.1
In 2006, living specimens were found off Turkey, making it the first invasive Erythrean sea urchin recorded in the Mediterranean.1
Goose barnacles of the genus Microlepas are known to live on it as parasites.1
It is considered one of the oldest living species in its genus, Diadema.1
Feññinoowo goonga
Fenaande: Black long-spined urchins are deadly and their stings can kill people.
Goonga: Their venom is mild and is not fatal to humans. The main problems are pain, swelling and spines that break off in the skin.1
