Elaphe climacophora

A spacious semi-arboreal terrarium, longer than tall but offering height, with sturdy branches, platforms and hides both high and low.

Minimum dimensions for an adult; larger is preferable for this active, climbing species (ideally 150 cm in length). A perfectly secured lid: it is a skilful and powerful escape artist.

A moderate environment. Increase occasionally (humid box, light misting) during shedding periods. Avoid stagnant humidity and poor airflow, which cause respiratory and skin problems.

Ban cedar and pine shavings (essential oils toxic to the respiratory tract). A substrate that retains slight moisture helps maintain humidity without becoming soggy.

Not strictly essential if the diet (whole prey) is balanced, but low UVB (5-6%, dimmed T5 type) is recommended for this diurnal species: it promotes natural behaviour and vitamin D3 synthesis. Always provide shaded areas.

A large bowl of clean water at all times, wide enough to let the snake immerse itself, especially before shedding. Clean and renew regularly.

Japan (Honshu, Hokkaido, Shikoku, Kyushu and neighbouring islands, including Kunashir). A temperate species occupying forests, forest edges, countryside and often old buildings.

Carnivore (mammal-eater/bird-eater) — Rodents suited to the snake's girth (mice, then rats); nestlings and quail eggs occasionally accepted.

Feed thawed prey of proportionate size (about the snake's widest girth). Juveniles every 5-7 days, adults every 10-14 days. Avoid overfeeding: this active species easily becomes obese in captivity. An excellent climber, often found hunting in the roof frames of old houses.

Clutch 4–12 eggs/young. Seasonal breeding triggered by a wintering period (brumation) at 10-15 °C for 8-12 weeks followed by a gradual warming. Laying in spring/summer; incubation of about 55-65 days at ~27-28 °C. One or sometimes two clutches per season in well-fed females.

• Respiratory infections (kept too cold, humid or poorly ventilated)
• Difficult sheds (dysecdysis) linked to insufficient humidity
• Mites (Ophionyssus natricis), especially in imports
• Internal parasites, common in wild-caught specimens
• Obesity and hepatic lipidosis from overfeeding; regurgitation if handled too soon after a meal or if the temperature is too low
