Description
Western Hognose (Watermelon)
Scientific Name: Heterodon nasicus
Common Name: Western Hognose Snake
Species Overview
Size: Adult females typically reach 2–3 feet (0.6–0.9 m) in length, while males average 1.5–2 feet (0.45–0.6 m). Both sexes feature the species’ characteristic upturned snout, adapted for digging and burrowing in loose soils.
Appearance: The Watermelon Western Hognose is a selectively bred line renowned for its warm, reddish-pink tones and exceptional colour balance. Through generations of refinement, breeders have enhanced natural red and orange pigmentation, resulting in snakes that display soft coral, peach, and rose hues across the body. The dorsal blotches are often muted or outlined in lighter tones, giving this morph a gentle, washed appearance compared to standard wild-type colouration. The Watermelon line stands out for its unique ability to combine pastel warmth with delicate contrast, making it one of the most visually appealing line-bred morphs in the species.
Distribution: Native to central North America, from southern Canada through the Great Plains and into northern Mexico.
Habitat: Western Hognose Snakes inhabit open prairies, grasslands, and semi-arid regions with sandy or loose soil ideal for burrowing. In captivity, this morph thrives in terrestrial terrariums with soft substrate, climbing décor, and secure hiding areas.
Behaviour: Western Hognoses are diurnal, curious, and alert snakes known for their dramatic bluff displays, which may include hissing, neck flattening, or mock strikes. These displays are harmless, and with regular handling, they settle into confident, inquisitive animals.
Captive Care
Enclosure: Provide an enclosure at least 3 feet × 18 inches × 18 inches for adults, using deep, soft substrate such as aspen, soil, or a sand-soil blend. Include multiple hides, smooth décor, and low branches for enrichment.
Temperature & Humidity: Maintain a daytime gradient of 78–86°F (25–30°C) with a basking area near 90°F (32°C). Allow nighttime drops to 70–74°F (21–23°C). Keep humidity between 30–50%, slightly increasing during shedding.
Diet: Offer thawed rodents approximately 1.25× the width of the snake’s mid-body. Feed juveniles every 4–5 days and adults every 7–10 days. Western Hognoses are reliable feeders that adapt easily to routine schedules.
Behaviour in Captivity: Hardy, engaging, and active, Western Hognoses thrive with consistent care and stable conditions. They are often seen burrowing or exploring during daylight hours and tolerate handling well once accustomed.
Special Considerations: Western Hognoses are mildly rear-fanged, and their venom poses minimal risk to humans unless an allergic reaction occurs. Handle calmly and house them individually to avoid feeding-related aggression or stress.
Genetics Note
Watermelon (Polygenic): A selectively bred line emphasizing enhanced pink, red, and peach tones. Breeders developed this line through careful selection of individuals with strong red and orange hues. Watermelon Western Hognoses are not defined by a single gene but by accumulated colour refinement over multiple generations, producing soft, warm pastel tones.
Genetic Combination Summary
The Western Hognose (Watermelon) expresses one polygenic trait:
-
Watermelon (Polygenic): Intensifies pink, red, and peach coloration through selective breeding.
The Watermelon line is a beautiful example of long-term selective refinement, producing snakes with subtle warmth and balanced colour. It serves as both a stunning display animal and a valuable foundation for combining with other morphs such as Arctic, Albino, or Toffee to enhance tone and saturation.
