The spotted jelly is a jellyfish with spots on the top of its bell, the rounded body. It lives in the warm Indo-Pacific oceans, and in some saltwater lakes in Palau and Indonesia. Its lake populations are famous because they have lost most of their sting.1

Anaishi

Indo-Pacific oceans, from the Fijian archipelago to the western Indian Ocean, and from Japan to Australia1

Bahari ya Pasifiki, Bahari ya Hindi, Bahari ya Matumbawe, Bahari ya Ufilipino, Bahari ya Timor na Arafura

Nyumbani

Lives in the open ocean across the Indo-Pacific, and in marine lakes, which are saltwater lakes cut off from the sea. Some Palau populations gather in huge groups called smacks, which are tourist attractions. The best-known spot is Ongeim'l Tketau Lake in Palau, also called Jellyfish Lake.1

Urefu

Kuogelea, makadirio

Hula nini?

Feeds on zooplankton and other tiny organisms, which it catches with its stinging cells. It also gets much of its nutrition from photosynthetic algae called zooxanthellae that live inside its tissues.1

Jinsi ya kumtambua

Distinctive spots on the top of the bell1
Colour ranges from greenish blue to olive green, from the algae living in its tissues1
Eight rhopalia (sensory organs) along the edge of the bell1
Eight frilled oral arms, each ending in a club-like appendage1
Numerous small mouths along the bottom of the oral arms, unlike many other jellies1

Nguvu ya sumu

Mikono inayodunga

Maelfu ya seli ndogo za kudunga hufyatuka kitu kikizigusa.

Sumu yake hufanya nini?

The venom is protein-based and is delivered by stinging cells called nematocytes (cnidocytes) on the upper surfaces of the oral arms. In jellyfish living in marine lakes, conditions in the lake are thought to break down this venom, so those populations do not sting humans.1

Ana hatari gani kwa watu?

Hatari kwa watu: HafifuKama kudungwa na nyuki au chini ya hapo. Kimsingi hana madhara kwa watu.

Jellyfish in the open ocean have stinging cells on their oral arms. Populations in marine lakes, such as Jellyfish Lake in Palau, do not sting humans.1

Akidunga

Toka majini na uondoe vipande vya mikono iliyonata (kwa glavu au kitambaa).
Kwa yavuyavu sanduku wa kitropiki: mimina siki kwenye sehemu zilizodungwa kwa angalau sekunde 30, omba msaada na uwe tayari kufanya CPR. Kwa mabotoli ya bluu na wengine wengi: suuza kwa maji ya bahari, kisha maji ya moto kupunguza maumivu.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Akikudunga: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

Lake populations of spotted jellies have lost most of their ability to sting, probably after being cut off in marine lakes long ago.1

Each day, spotted jellies rise to the surface and follow the sun from east to west, so their algae can photosynthesise.1

Lake jellyfish are over three times wider than ocean ones, yet their tentacles are about the same length.1

Unlike many jellies, spotted jellies have several small mouths along their oral arms.1

A sea anemone called Entacmaea medusivora preys on spotted jellies, catching them in its tentacles.1

At night they stay lower in the water column.1

Kuvunja dhana potofu

Dhana potofu: All spotted jellies sting people.

Ukweli: Ocean populations have stinging cells, but the jellyfish in marine lakes such as Jellyfish Lake in Palau do not sting humans.1
