🚨 Cảnh báo: Ăn cá mang (cá nóc) có thể gây ngộ độc tetrodotoxin nguy hiểm, khiến người bệnh hôn mê sâu, nguy cơ ngừng thở và tim ngừng. Độc tố mạnh gấp 275 lần xyanua! Hãy kiểm tra nguồn gốc thực phẩm và tránh ăn cá chưa được kiểm định an toàn. #SứcKhỏe #Health #CáMang #FoodSafety #Tetrodotoxin #Poisoning #AnToanThucPham #FoodSafetyVietnam.

don't just chop it up:

each segment will grow into a new #hammerheadWorm 😬

the #tetrodotoxin (same neurotoxin in pufferfish) in hammerhead worms is a threat to your cats and dogs

and as R. Scott says, to you:

do *not* handle it

#birds tend to avoid them, but some species can eat it

the threat the hammerhead worms pose to birds' food sources is the greater concern

the current thinking is that birds will not be able to control the hammerhead worm invasion

Octopus mating involves a nasty sting

During mating, some male octopuses inject females with their potent venom to paralyse them – and avoid being eaten by their mates.

Dolphins enjoy pufferfish as a recreational drug.

Pufferfish produce a tetrodotoxin - 1,200 times more poisonous than cyanide - which, in small doses, gives dolphins a pleasurable buzz.
