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

  • 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

Dintlha

1

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

2

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

3

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

4

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

Mosenyi wa ditlhamane

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

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