The Cualtzinatl, colloquially referred to as a cualtzin, is a crocodilian reptile that lives in tropical and subtropical climates in small social groups. They measure on average 6-7 feet for females and 5-6 feet for males. They inhabit brackish and saltwater mangrove wetlands, most frequently in estuaries with inlets to saltwater bodies of water.

 

Cualtzins are carnivorous and consume small mammals, fish, amphibians, and birds. When the female is ready to breed, she relocates to deep water and uses infrasound to attract males. They then compete for breeding rights. The young have stripes for camouflage and live with their local family groups for up to two years before leaving to join a non-family group.
