Clelia clelia
Clelia cleliaAlso known as Black Mussurana, Windward Cribo
Adult mussuranas display an iridescent gunmetal-black or dark blue body, contrasting sharply with the bright coral-pink coloration of juveniles. Famous for immunity to pit viper venom, these formidable constrictors actively hunt and consume highly venomous snakes such as lanceheads and bushmasters. They rely on swift strikes, powerful muscular coils, and rear-fanged teeth to overpower prey before swallowing it whole.

Responsible observation
- Observe from a Distance: Maintain a comfortable distance to observe natural foraging behavior without causing stress.
