water monitor lizard (Varanus salvator), a massive reptile native to South and Southeast Asia, captured headlines in July 2025 when a 5-foot pet named Goose escaped in Webster, Massachusetts, and was spotted in Connecticut. Known for its powerful tail, sharp claws, and aquatic prowess, this second-largest lizard species after the Komodo dragon thrives in diverse habitats, from mangrove swamps to urban canals. For U.S. readers intrigued by this exotic creature, this article explores the water monitor’s biology, its role in ecosystems, its status in the pet trade, and lessons from the 2025 escape, drawing parallels to U.S. invasive species challenges.
Biology and Characteristics of the Asian Water Monitor
The Asian water monitor, part of the Varanidae family, is a formidable carnivore that can grow up to 9 feet and weigh 40–90 pounds, with exceptional cases reaching 165 pounds. Key traits include:
- Appearance: Dark brown or black with yellow spots that fade with age, a long neck, elongated snout, and a laterally compressed tail used as a rudder for swimming.
- Diet: Opportunistic carnivores, they eat fish, frogs, crabs, birds, small mammals, snakes, juvenile crocodiles, and even carrion or human food waste. In urban Thailand, they’ve consumed domestic cats, dogs, and turtle eggs.
- Behavior: Excellent swimmers, they can stay submerged for 30 minutes and use their forked tongues, like snakes, to smell prey via the Jacobson’s organ. They pursue prey actively rather than ambushing.
Breeding occurs from April to October, with females laying 15–40 eggs per year in termite mounds or burrows, which hatch after 5–10 months. Males are typically larger, reaching maturity at 1 meter, females at 50 cm.
Habitat and Distribution
Native to South and Southeast Asia, including Sri Lanka, India, Thailand, Malaysia, and Indonesia, water monitors inhabit mangrove swamps, rivers, wetlands, and urban areas like canals and city parks. They thrive in tropical environments below 1,000 meters elevation but face threats from habitat loss due to palm oil plantations and timber harvesting. Their adaptability allows them to survive near human settlements, scavenging food waste or preying on small animals.
In the U.S., they’re an invasive species in southeastern states like Florida, where escaped or released pets have established populations, similar to Burmese pythons.
The 2025 Massachusetts-Connecticut Escape
On July 18, 2025, a 5-foot water monitor named Goose escaped from an unpermitted home in Webster, Massachusetts, near Blueberry Lane. By July 26, it was spotted in Thompson, Connecticut, near Little Pond, prompting warnings from authorities. Described as non-aggressive but capable of inflicting bacterial infections via bites, Goose’s escape highlighted the risks of exotic pet ownership. Webster Animal Control (508-943-1212) and Connecticut State Police (860-779-4900) urged residents not to approach the lizard, noting its ability to climb trees and seek water. The illegal ownership sparked investigations, as Massachusetts requires permits for such reptiles.

Water Monitors in the Pet Trade
Asian water monitors are popular in the U.S. pet trade, with breeders like New England Reptile offering captive-bred Black Dragons and Albinos, socialized and fed insects, eggs, and minced meat. However, their large size (up to 9 feet), high maintenance, and need for spacious enclosures make them unsuitable for casual owners. Bites, while rare and not fatally venomous, can cause infections due to bacteria, requiring medical attention. In Singapore, it’s illegal to remove them from the wild under the Wildlife Act, and their skins are hunted for leather and traditional medicine, with over 1.5 million skins exported annually.
Ecological Role and U.S. Parallels
Water monitors control prey populations (e.g., rats, snakes) and act as scavengers, aiding biomass recycling. Their consumption of carrion, including human remains in Sri Lanka, can complicate forensic investigations but also highlights their ecological adaptability. In the U.S., their invasive presence in Florida mirrors issues with species like the Nile monitor, which disrupt ecosystems by preying on native wildlife. The U.S. Fish and Wildlife Service reports invasive reptiles cost millions annually in control efforts, a lesson for regulating exotic pet trades.
Tips for U.S. Readers in 2025
