Habitat and Distribution in Texas

Plain-bellied watersnakes are highly adaptable and found across diverse habitats in Texas. Their presence is closely tied to water sources:

Rivers and Streams: They frequent slow-moving rivers, creeks, and streams.
Lakes and Ponds: They are commonly found along the shorelines of lakes and ponds.
Marshes and Swamps: These snakes thrive in marshy areas and swamps.
Agricultural Areas: Their adaptability often leads to sightings in and around agricultural fields with nearby water bodies.

They are widespread across Texas, excluding the higher elevations of the western and Trans-Pecos regions.

Diet and Feeding Habits

The Plain-bellied Watersnake is a skilled predator, relying on a diet primarily consisting of:

Fish: Fish form a significant portion of their diet.
Amphibians: Frogs, toads, and salamanders are also consumed.
Crayfish: These crustaceans are a regular part of their meals.
Other Small Animals: Occasionally, they may consume small rodents or birds.

Their ambush predation strategy involves patiently waiting near water sources, striking swiftly when prey comes close.

Behavior and Ecology

Plain-bellied watersnakes are primarily aquatic or semi-aquatic snakes. They are generally diurnal (active during the day), often seen basking on rocks, logs, or vegetation near the water's edge to regulate body temperature. They are excellent swimmers and divers.

Defense Mechanisms: When threatened, these snakes may flatten their bodies, hiss, and strike defensively, though they are not venomous. They may also release a foul-smelling musk.

Conservation Status and Threats

While not currently considered endangered, habitat loss and degradation pose the greatest threats to Plain-bellied Watersnakes in Texas. Pollution of waterways and the destruction of riparian zones negatively impact their populations.
