Savigny's long-spined urchin

Diadema savignyi
Ku saabsan magaca: The species name honours Marie Jules César Savigny, a French zoologist who described many new marine species from the Mediterranean and Red Sea.1

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

Wuxuu ku nool yahay
East coast of Africa, Red Sea, Indian Ocean, western Pacific, French Polynesia, Hawaii, New Caledonia and northern Australia1

Bogga hore
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

Muxuu cunaa?
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

Sida loo aqoonsado

  • 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

Inta badan lagu khaldaa: 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

Awoodda sunta

Qodxo sun leh

Qodxo fiiqan ayaa sunta sidda. Haddii aad ku tunto ama aad qabato wuu xanuunjiyaa.

Intee buu dadka khatar ugu yahay?

Khatarta dadka: Xanuun badanAad buu u xanuunjin karaa, laakiin ku dhowaad weligiis khatar weyn ma aha.

Muxuu sameeyaa marka uu baqo?

When a shadow falls on it, it angles its spines towards the possible attacker.1

Haddii qodxihiisu ku dhex galaan

  • Nabarka geli biyo kulul, inta qofku u adkaysan karo isagoo aan gubanayn, oo hel caawimaad caafimaad si qodxaha looga saaro. Ha isku dayin inaad adigu qodo.

Marka hore had iyo jeer wac lambarka gurmadka degdegga ah (112, 000, 911). Kani waa hage guud oo gargaar degdeg ah, ma aha talo caafimaad. Aasaaska gargaarka degdegga ah

Badbaado

  • Weligaa ha taaban, ha qaban, hana ku ciyaarin xayawaan duurjoog ah, xitaa mid yar, xitaa haddii uu u muuqdo inuu hurdo ama dhintay.
  • Meel u bannee. Haddii aad mid la kulanto, deg, tartiib dib ugu noqo oo u daa inuu jidkiisa maro.
  • Haddii qodxihiisu ku dhex galaan: deg, ha dhaqaaqin, wac lambarka gurmadka degdegga ah (112, 000, 911) ama si degdeg ah u tag isbitaalka. Xusuuso sida uu u egyahay, sawir ayaa caawiya.

Kuma raadinayo. Suntiisa wuxuu u isticmaalaa inuu cunto ku qabsado ama isku difaaco, wuxuuna aad u door bidaa inuu dhuunto. Wax badan oo ku saabsan badbaadada

Xaqiiqooyin

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
