While hiking around the edge of these mangroves, marshes, and estuaries, we catch snakes by hand and perform various morphometric data right there in the field. If they feel particularly stressed or agitated, they will resort to biting.
Nerodia clarkii give Over many generations that are breeding, the pure compressicauda species could eventually be lost to extinction because of the hybrids different DNA. Water snakes carry no venom in their bite, and that takes a huge load of stress and worry off your shoulders.
In state park areas of this study, these methods were all done legally with permits which is usually always required in these types of studies. Young snakes are 7 to 9 inches (17 to 22 cm) long at birth, and live up to 20 years.
