Orange Bellied Newt

Taricha torosa

Description:

Like other Taricha members, the glands in the skin of T. torosa secrete the potent neurotoxin tetrodotoxin, which is hundreds of times more toxic than cyanide. This is the same toxin found in pufferfish and harlequin frogs. Researchers believe that bacteria synthesize tetrodotoxin and the animals that employ the neurotoxin acquire it through consumption of these bacteria. This neurotoxin is so strong that it is enough to kill most vertebrates, including humans. However, they are dangerous only if ingested, and can be safely kept as pets. Due to their toxicity, the California newt has few natural predators. Garter snakes are the most common, and some species have developed a genetic resistance to tetrodotoxin.

Habitat:

California newts exist primarily on the California coastline and in the Sierra Nevada. This is because they prefer less humid climates than the rough skinned newts. During the non-breeding season the newts are land dwelling, preferring rock crevices and logs. While breeding, the subspecies torosa torosa prefers slow moving pools in coastal streams
