The Atlantic sea nettle is a jellyfish that lives along the Atlantic coast of the United States. It has a bell-shaped body and stinging tentacles that it uses to catch food and to defend itself. Its sting is painful for people, but it is not strong enough to cause death except through an allergic reaction.1

Apa yang ia makan?

It feeds mainly on zooplankton, ctenophores, other jellies and sometimes crustaceans. It uses its stinging tentacles to immobilise prey, then moves the food into its gastrovascular cavity, a body cavity used for digestion.1

Cara mengenalinya

Bell-shaped body that is usually semi-transparent1
Small white dots and reddish-brown stripes on the bell1
Typically pale, pinkish or yellowish, with deeper stripes near the edge of the bell1
Bells without stripes look white or opaque1
Smaller than the Pacific sea nettle1

Sering dikelirukan dengan: It was often confused with several other Chrysaora species, so older reports of this jellyfish from other parts of the Atlantic and other oceans may be wrong. C. chesapeakei, found in estuaries on the Atlantic coast of the United States and in the Gulf of Mexico, was only recognised as a separate species in 2017. The Atlantic sea nettle is smaller than the Pacific sea nettle and has more variable colouring.1

Sesungut yang menyengat

Ribuan sel penyengat kecil melepaskan sengat apabila sesuatu menyentuhnya.

Apa kesan bisanya?

Each tentacle is covered in thousands of microscopic cells that fire venom-coated stinging filaments on contact. The venom can kill smaller prey or stun predators. In people, the sting most likely causes a painful but non-lethal rash that usually lasts about 20 minutes. Some earlier reported stings in the Philippines caused vascular insufficiency (poor blood flow) and mononeuritis (inflammation of a nerve).1

Berapa bahaya ia kepada manusia?

Bahaya kepada manusia: MenyakitkanIa boleh jadi sangat sakit, tetapi hampir tidak pernah serius.

Its sting is rated from moderate to severe. It is not potent enough to cause human death, except through an allergic reaction. While the sting is not particularly harmful, it can cause moderate discomfort.1

Apa yang ia buat apabila takut?

When touched, its tentacles fire venom-coated stinging filaments that stun or deter a perceived predator.1

Jika ia menyengat

Misting vinegar over the affected area can neutralise the sting. This stops unfired stinging cells from firing and adding to the discomfort.1
Keluar dari air dan tanggalkan semua sesungut (dengan sarung tangan atau kain).
Untuk obor-obor kotak tropika: tuang cuka pada sengatan sekurang-kurangnya 30 saat, panggil bantuan dan bersedia melakukan CPR. Untuk bluebottle dan kebanyakan yang lain: bilas dengan air laut, kemudian air panas untuk menghilangkan sakit.
