What are the adaptations of arapiamas?

Arapaimas, large Freshwater Fish native to the Amazon Basin, have several adaptations that enable them to thrive in their environment. They possess a specialized swim bladder that functions like a lung, allowing them to breathe air and survive in oxygen-poor waters. Additionally, their streamlined bodies and powerful pectoral fins enable efficient swimming, while their tough, armor-like scales provide protection from predators. These adaptations make arapiamas well-suited for the dynamic conditions of their aquatic habitats.
