Eurycea bislineata male or female

[Erwin Bakker]

Eurycea bislineata male or female?

Hi Erwin,
Depending on the subspecies the increased muscles and cirri on the head only appear during the breeding season.
You can check the cloaca to see if it has papillose clocal lips as the females have smooth cloacal lips (may need a magnifying glass).

Hi Ed,

Thanks, this animal sometimes has a bump between the dorsum and the tail.
