Mod Pick During mating season, male red salamanders are not aggressive towards each other. In fact, they actually court one another — this likely isn't a case of mistaken sex, but an attempt to trick rival males into wasting their sperm packets (spermatophores).

The red salamander is known as a 'lungless salamander' (a plethodontid) and it indeed doesn't have any lungs. Instead, it breathes directly through its skin — an ability called 'cutaneous respiration'.

Along the sides of its body, it has 16–17 vertical grooves, each one corresponding to a space between the salamander's ribs. These are called 'costal grooves' and they function to transport water over the surface of the body by providing channels through which it can run, helping to keep the salamander's skin moist and fit to respire effectively.

The diet of a red salamander consists mostly of small invertebrates like insects, spiders, and worms. To catch them, it uses a projectile tongue that can extend and retract in milliseconds.

When threatened by a predator, this salamander will coil its body into a C-shaped defence posture. It also possesses glands that can produce a toxic secretion.

A male red salamander begins courting a female by rubbing his snout on hers. He then wriggles and squeezes his way beneath her body, until his head is beneath her tail and her head is on top of his tail. They walk around like this for a few minutes until the male drops his sperm packet (called a 'spermatophore').

He uses his tail to guide the female to the sperm packet — waving it in the air, from side to side, like a happy dog — until she picks it up.

In autumn, the female sticks her clutch of 30–130 eggs to the underside of a stream-side rock or log. She guards them for 2 to 3 months until they hatch, then they are on their own.

A red salamander's larval period can last anywhere from 1.5 years in coastal regions where elevation is near sea level, to 3.5 years in the colder, higher altitude regions of New York — the highest altitude that red salamanders live at is around 1,500 metres (4,920 ft).

Neat.

What does the female do with the sperm packet?

Shove it in her? Eat it?

u/IdyllicSafeguard Sep 01 '24

Basically the former. A female salamander lowers herself onto the spermatophore and uptakes it into her reproductive tract to fertilize her eggs.
