Editor’s Note: The southern watersnake is part of the CROW CAW (Case A Week) series, which tells the stories of patients at the Clinic for the Rehabilitation of Wildlife on Sanibel Island, the dangers they face, and how we can help protect our wildlife. Read previous cases here.
A southern watersnake (Nerodia fasciata) was brought to the Clinic for the Rehabilitation of Wildlife after being found with multiple puncture wounds and lacerations along its back. The pattern and location of the injuries suggest that an attack from another animal likely caused them. Although the snake was thin and appeared to be in poor body condition, it remained alert and responsive during the initial examination.
Radiographs also revealed multiple broken ribs, meaning the snake sustained significant internal trauma. Blood tests also showed evidence of infection and anemia, which may have been related to the snake’s wounds, blood loss, or overall weakened condition. The snake received pain medication to keep it comfortable, and antibiotics to treat the suspected infection.
Veterinary staff cleaned the snake’s wounds with an antiseptic solution and topical medication. The snake will remain in an enclosure for rest and continue receiving supportive care while its wounds and rib fractures heal.
Getting to Know the Southern Watersnake
Southern watersnakes are native to mainland Florida, including Southwest Florida. They are commonly associated with freshwater habitats such as ponds, marshes, swamps, wetlands, and drainage ditches. They may also be found in suburban neighborhoods where development meets natural wetland habitat.
These stout-bodied snakes often have dark brown, reddish, or black bands across a lighter-colored body. Their coloring varies considerably, and some older individuals become so dark that their distinctive banding is hard to see.
As their name suggests, watersnakes are closely associated with aquatic environments. They primarily eat fish and frogs, helping maintain the balance of local aquatic ecosystems. They also play an important role in the food web, serving as prey for other wildlife. Although they are sometimes mistaken for the venomous Florida cottonmouth, Southern watersnakes are nonvenomous.
When threatened or cornered, they may flatten their bodies, strike defensively, or bite. However, their usual response to a potential threat is to escape into the water or seek shelter. Giving snakes plenty of space allows them to move away without unnecessary conflict.
Protecting Southwest Florida’s Native Wildlife
If you encounter an injured snake, do not attempt to handle it yourself. Keep people and pets at a safe distance and contact a qualified wildlife rehabilitator for guidance. Protecting Southwest Florida’s Native Wildlife
Wildlife encounters are a natural part of life in Southwest Florida, where residential communities often share space with wetlands and other important habitats. Understanding the animals that live alongside us can help reduce fear and encourage safer coexistence.
This southern watersnake’s injuries highlight the importance of veterinary care for injured wildlife. As it recovers, CROW’s veterinary team will monitor its progress and adjust treatment as needed. Each patient has different needs, but the goal remains the same: to help them recover and return to the wild.
