The grey side-gilled sea slug is a soft-bodied sea snail without a shell, found in the sea around New Zealand, south-eastern Australia and parts of Asia. It is poisonous rather than venomous: it does not bite or sting, but eating it can be dangerous. It became a public concern in New Zealand in 2009, when several dogs died after eating it.1

Siyatyhefa okanye sinetyhefu? Izilwanyana ezinetyhefu zitofa ityhefu ngokuluma okanye ngokuhlaba. Izilwanyana ezityhefayo ziyingozi xa uzichukumisa okanye uzitya. Esi siyatyhefa.

Sihlala

New Zealand, south-eastern Australia, China, Sri Lanka and Japan; introduced to the coast of Argentina in 20091

Ekhaya

It lives between the tide marks in harbours and in the sea down to about 6 m, or deeper, off rocky coasts. It is often washed ashore during spring storms, so people may find it on beaches.1

Ubude

8 cm ukuya ku-10 cm (3,1 in ukuya ku-3,9 in)1

Esona santya siphezulu

malunga ne-0,5 km/h (0,31 mph)

Sitya ntoni?

It is an opportunistic carnivore that eats other soft-bodied invertebrates, especially sea anemones. It also takes marine worms, mussels, dead or dying animals, and other sea slugs of the same genus.1

Amandla etyhefu

Siyatyhefa xa sityiwa

Siyingozi kuphela ukuba kukho into esityayo.

Ityhefu yaso etyhefayo (xa usichukumisa okanye usitya) yenza ntoni?

It does not have venom. Its harm comes from tetrodotoxin, a poison that attacks the nerves. In 2009, several dogs in the Auckland Region of New Zealand died of tetrodotoxin poisoning after eating this slug on beaches.1

Siyingozi kangakanani ebantwini?

In 2009, several dogs died in the Auckland Region after eating this slug, and children and pet owners were asked to avoid beaches. Recreational fishing was also interrupted for a time. Investigators found the slugs most likely picked up the poison from dead fish they fed on, and similar poisoning has not happened again.1

Ukuba umntu usichukumisile okanye usityile

Ukuba umntu usityile okanye uneempawu emva kokusitya: tsalela inombolo kaxakeka okanye iziko lezityhefu (poison centre) ngoko nangoko.

Soloko utsalela inombolo kaxakeka kuqala (112, 000, 911). Esi sisikhokelo soncedo lokuqala ngokubanzi, asilocebiso lwezonyango. Iziseko zoncedo lokuqala

Hlala ukhuselekile

Ungaze uchukumise, ubambe okanye uqhule isilwanyana sasendle, nokuba sincinci, kwaye nokuba sibonakala silele okanye sifile.
Sinike indawo. Ukuba udibana naso, hlala uzolile, buyela umva kancinci kwaye usiyeke sihambe ngendlela yaso.
Ukuba usichukumisile okanye usityile: musa ukukhuhla amehlo okanye umlomo wakho, hlamba izandla zakho kwaye ufumane uncedo lwezonyango.

Asikuzingeli. Ityhefu yaso ikhona nje ukuze kungabikho nto isityayo. Okungakumbi malunga nokuhlala ukhuselekile

Iinyaniso

Its poison is tetrodotoxin, the same kind of toxin found in some pufferfish.1

It has no shell, although it is a type of sea snail (gastropod mollusc).1

It lives for 2 to 3 years and dies after spawning in winter.1

It has spread far beyond its native range, reaching about 2,000 km of the south-western Atlantic coast after it was first reported in Argentina in 2009.1

Its eggs hatch into free-swimming larvae that drift as plankton for about three weeks before settling.1

Umqhekezi weentsomi

Intsomi: Every grey side-gilled sea slug is dangerously poisonous.

Inyaniso: Differences in toxicity between regions are likely due to differences in diet, not to separate species. The poison most likely comes from the food the slug eats, such as dead fish.1
