Black sea nettle

Chrysaora achlyos
Ka lebitso: Chrysaora comes from Chrysaor, a figure in Greek mythology, and means "he who has a golden sword". The species name comes from a Greek word meaning mist, darkness or obscurity, which refers to its colour and how rarely it is seen.1

The black sea nettle is a large jellyfish with a dark purple to nearly black bell. It lives in the Pacific Ocean off western North America, and it is rare to see except in big swarms that appear in some years. Its stinging tentacles can cause a painful sting to people.1

It lives in nearshore waters and is occasionally seen in surface waters, sometimes in very large swarms. Swarms have been recorded off Baja California and southern California.1

Ho e tseba jwang

  • The bell is an opaque dark purple to nearly black colour.1
  • The edge of the bell has a lighter brown, net-like (reticulated) pattern.1
  • The bell can reach about 1 metre across, and the oral arms can extend 5 or 6 metres.1
  • There are marginal sense organs around the bell edge, one after every set of 3 tentacles, 8 in total.1

Hangata e ferekanngwa le: No other West Coast jelly that visits nearshore waters has this dark pigmentation, so the very dark colour is the main way to tell it apart.1

Di-tentacle tse hlabang

Dikete tsa disele tse nyenyane tse hlabang di thunya ha ho na le se di amang.

Chefo ya yona (eo e e kenyang ka ho loma kapa ho hlaba) e etsang?

Each tentacle is covered in thousands of microscopic stinging cells called nematocysts. When touched, they fire a filament that injects toxins, which can kill smaller prey or stun predators. In people, the sting is usually not lethal but is painful and can last for forty minutes.1

E kotsi hakae ho batho?

The sting is usually not lethal to people, but it is painful and can last for about forty minutes.1

E etsang ha e tshohile?

Its stinging tentacles fire venom-filled filaments on contact, which stun or deter anything that threatens it.1

Dintlha

1

It is thought to be the largest invertebrate described in the 20th century.1

2

Its stomach is lined with fibrous vessels that attach to prey, and its mouth-like openings, called darkmaws, close when exposed to bright light.1

3

It was only officially described in 1997, after large groups were found on the Pacific coast.1

4

Its swarms seem to coincide with red tides, which are blooms of the zooplankton it feeds on.1
