Savigny's long-spined urchin is a spiny sea animal that lives on reefs and in shallow lagoons. It has very long, thin spines that can grow up to 25 cm, and it comes out at night to graze on algae. Its spines are the part that can hurt people, so it is worth giving it plenty of room.1

Gida
It is found on mixed sandy, rocky and coral seabed, especially in places disturbed by storms or other natural events. It lives from the surface down to about 70 metres deep. It often hides in crevices or under boulders during the day.1

It feeds at dusk on the algal mat that grows over the seabed, tearing it up as it grazes. This helps keep algae from overwhelming corals.1

Yadda za ka gane shi

  • Usually black, with a rounded body (called a test) up to about 9 cm across1
  • Long, thin, hollow spines that grow in tufts and can reach 25 cm; they are usually black but can be grey, dark brown or purple1
  • Juveniles may have bands of lighter and darker shades, and the occasional individual is completely white1
  • Iridescent green or blue lines around the interambulacral areas and around the periproct (the cone-shaped region surrounding the anus)1

Ana yawan rikita shi da: It is very similar to Diadema setosum, which shares much of its range and often lives in the same groups. Savigny's long-spined urchin lacks the thin orange ring around the periproct that Diadema setosum has.1

Bayanai

1

Its spines are brittle, thin and hollow, and grow in tufts that can be as long as 25 cm.1

2

Small fish such as cardinal fish, flatworms and shrimps sometimes shelter among its long spines.1

3

It spawns just after the full moon, while its close relative Diadema setosum mostly spawns around days eight to ten of the lunar cycle, which keeps the two species from interbreeding.1

4

Its grazing helps control algae, which might otherwise smother corals.1

5

It is nocturnal, hiding in crevices or under boulders by day, though several individuals sometimes huddle together in the open.1

6

Its predators include pufferfish, porcupinefish, lobsters and snails.1

It does not have live young. Instead it releases eggs and sperm into the water (spawning), mainly during the north-east monsoon period, peaking in May, and timed to the lunar cycle.1
