May 24th 2020 my female Thamnophis cyrtopsis collaris , the Tropical Black-necked Garter Snake gave birth to a nice litter of big babies.

The biggest one, a male, measured 27,5 cm total length.

On the pictures you see some of the babies and an adult pregnant female.

This subspecies occurs only in Mexico.
