The compass jellyfish is a common jellyfish that lives in cool coastal seas of the northeast Atlantic, including the North Sea and the Mediterranean. Its bell has a pattern that looks like the face of a compass, which gives it its name. Its tentacles carry stinging cells, so it is best left alone.1

Anaishi

Coastal waters of the northeast Atlantic, including the Celtic, Irish, North and Mediterranean Seas1

Bahari ya Atlantiki, Bahari ya Mediterania, Bahari ya Kaskazini

Nyumbani

It lives in shallow coastal water and moves up and down the water column, mostly near the surface and down to just above the seabed. It is rarely found deeper than 30 m.1

Urefu

15 cm hadi 25 cm (5.9 in hadi 9.8 in)1

Kasi ya juu

takriban km 0.7 kwa saa (maili 0.44 kwa saa)

Kuogelea, makadirio

Hula nini?

It eats other marine invertebrates and plankton, including dinoflagellates, copepods, crustacean eggs, larval fish and chaetognaths. It stuns and catches prey with stinging cells on its tentacles, then its oral arms move the prey into its mouth.1

Jinsi ya kumtambua

Adults have a bell 15 to 25 cm across, usually yellowish white with some brown.1
The bell has 16 brown, elongated V-shaped markings around a central brown spot.1
It has 24 tentacles arranged in eight groups of three.1
It has four oral arms that are noticeably longer than the tentacles and look folded and frilly.1
Juveniles lack the compass pattern. They look white and polka-dotted, with a reddish fringe on the bell edge.1

Mara nyingi huchanganywa na: Records of this species from the southeastern Atlantic, including South Africa, were caused by confusion with close relatives: C. africana, C. fulgida and an undescribed species tentatively called "C. agulhensis".1

Nguvu ya sumu

Mikono inayodunga

Sumu yake hufanya nini?

Each tentacle has stinging cells used to capture prey and to defend against predators. Jellyfish stings are painful and can be deadly to 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.

inafaa kujua

Ukweli

Males release sperm from their mouths into the water, and females can fertilise sperm from several males.1

Adults often carry a parasite called Hyperia medusarum, which settles inside the body, especially the gonads.1

Compass jellyfish have very few predators. Leatherback sea turtles and ocean sunfish are known to eat them.1

Warmer winters allow longer release periods for young, and the species is predicted to move further north as the seas warm.1

Kuvunja dhana potofu

Dhana potofu: Compass jellyfish live in the southeastern Atlantic, including South Africa.

Ukweli: Earlier records from there were due to confusion with close relatives. The species lives in the northeast Atlantic.1
