The male red-bellied newt often has a dark, broad coloring across the vent, while females do not. Breeding males develop smooth skin and a flattened tail. The red-bellied newt can be distinguished from other coastal newts by its red belly and a lack of yellow in its eyes.

about 12 streamlined clusters with six to 16 eggs each, and the eggs are typically attached to the bottoms of rocks, or on branches and roots leaning into the stream. When the adults leave the stream, instead of moving directly uphill, they move at an angle that leads them somewhat upstream. The females, unlike the males, do not breed every year.

Because red-bellied newts are so poisonous, they are nearly inedible and have no reported predators other than a few species of snake which are resistant to the toxin. Like other newts, red-bellied newts have the ability to

Newts begin their lives as aquatic larvae similar to tadpoles, though elongated and with external gills. Once newt larvae mature into their adult form, which takes about four to six months, they will leave the water and live underground until they are ready to breed, which is typically in four to six

After reaching reproductive maturity, male red-bellied newts start congregating at stream banks as early as
January or February. One to three weeks later, the females join them and the newts mate. Red-bellied newts lay their eggs in fast-flowing streams or rocky rivers. The females lay their eggs in

Red-bellied newts have a brownish-black topside to avoid being noticed. When that fails, and they are seen and disturbed, they pull their heads and tails back to reveal their bright-red undersides. This serves as a warning to potential predators, as red-bellied newts have enough of a
