Boa constrictor
Large boa from Central/South America. Grows larger than ball pythons but relatively docile. Morph variety increasing. Colombian boa recommended for beginners.
The boa constrictor (Boa constrictor) is a large boid snake distributed widely from Central America to South America. Adults range from 150 to 300 cm in length with considerable variation between individuals and locales, and they subdue prey by constriction (they are non-venomous). The base coloration is brown or grey with a series of saddle-shaped markings along the back, and many color morphs have been bred in recent years. Many individuals are relatively docile, making the species comparatively manageable among large snakes, but adults are very large and powerful and require a sturdy, spacious enclosure with a proper temperature gradient and hides. They are fed thawed frozen rodents. With a long lifespan, this is a long-term commitment suited to intermediate keepers.

ボアコンストリクターはモルフ市場が非常に発達しており、共優性(スーパー体ができる:ハイポ・サーモン・モトリー・ジャングル・アステカ・IMG等)と劣性(アルビノ・アネリ・レオパード等)を組み合わせたコンボが流通の中心。サーモンの不完全優性は学術論文で確認。ブラッドは出典により劣性/共優性の記述が割れるため遺伝形式を記載しない。
