Upon arriving at any of the scenic and popular islands of western Lake Erie, visitors encounter an unusual message: "Watersnakes welcome here!" More than 200 signs describing a unique creature, the Lake Erie watersnake (Nerodia sipedon
insularum), are found on most of the U.S.
The snake in question is a northern water snake, Nerodia sipedon
. The banding pattern on the copperhead and water snake are very different and easily recognized once you become familiar with them.

Blood samples were obtained from seven snake species (Coluber constrictor, Elaphe vulpine vulpine, Nerodia sipedon
sipedon, Regina grahamii, Sistrurus catenatus catenatus, Thamnophis radix and Thamnophis sirtalis parietalis) from Squaw Creek National Wildlife Refuge located in northwest Missouri.
We used more than 326 000 observations of temperature collected by radio telemetry from 38 individuals over three years to investigate thermoregulation and thermal relations of northern water snakes (Nerodia sipedon
) near the northern limit of their distribution in Ontario, Canada.

For example, Tiebout and Cary (1987) observed northern watersnakes (Nerodia sipedon
) basking out of water in vegetation most frequently in spring, and Graham (2013) observed a spring bias in arboreal behavior by plainbelly watersnakes (Nerodia erythrogaster), northern watersnakes, and brown watersnakes (Nerodia taxispilota).
For example, Pough (1978) reported that juvenile Nerodia sipedon
did not attempt to defend themselves against threats, but instead fled a short distance and hid.
The purpose of this study was to determine if methylmercury is maternally transferred placentally in Northern Water Snakes (Nerodia sipedon
French explorers in the 1700s noted an abundance of serpents and named the western Lake Erie islands the "Islands of the Snakes." Accounts from the late 1800s described watersnakes "sunning themselves in heaps, knots, and snarls." In the early 1900s, when this subspecies was described scientifically as the Lake Erie watersnake (Nerodia sipedon
insularum), it could still be found in large numbers.
The least frequently encountered species was the northern water snake (Nerodia sipedon
; n = 1, 0.4%).
A test of the thermal coadaptation hypothesis with black rat snakes (Elaphe obsoleta) and northern water snakes (Nerodia sipedon
Relative clutch mass (RCM), the ratio of total mass of a clutch to the postpartum body mass of the female, is considered by many a life history trait that indirectly quantifies reproductive effort in snakes, The Northern Watersnake (Nerodia sipedon
sipedon) is one of the most abundant and widespread species of snake within Ohio.
Lake Erie Water Snake (Nerodia sipedon
insularum) The Lake Erie water snake is a nonvenomous snake that lives only on the islands and in the waters of the western Lake Erie basin.
