The cribo is a member of the Drymarchon genus, as is the Indigo snake of the Southeastern United States.
Within this genus, the Yellowtail cribo is the longest, and has been known to reach 10 feet (3.05m) in length. Its cousin, the indigo snake, is the longest snake in North America, as the cribo's distribution is limited to Central and South America.
It is carnivorous and will eat any other small animal it can overpower. As it is not a constrictor and is nonvenomous, it subdues prey by thrashing it about until it can pin it down and swallow it whole.
Species in this genus include:
