Can your turtle die if he eats a puffer fish?

Pufferfish, also known as blowfish, are highly toxic to most animals, including turtles. Pufferfish contain a toxin called tetrodotoxin, which is a potent neurotoxin that can cause paralysis and respiratory failure. Even a small amount of tetrodotoxin can be fatal, and there is no known antidote. If you suspect your turtle has eaten a pufferfish, seek professional veterinary care immediately. Symptoms of pufferfish poisoning include:

Loss of appetite

Vomiting

Diarrhea

Lethargy

Difficulty breathing

Paralysis

Death

If you observe any of these symptoms, take your turtle to a veterinarian as soon as possible.
