In the calm waters of Baía das Raias, you'll find various types of rays gliding gracefully beneath the surface. The "typical" rays have pectoral fins that extend from their bodies in a rounded or diamond shape. These fascinating creatures fall into three main categories: true rays, which have small dorsal fins at the tip of their tails; stingrays, equipped with venomous spines for defense against predators; and electric rays, capable of generating electric shocks.
Rays, also known as skates or batoids, are marine, cartilaginous fish, meaning their skeletons are made of cartilage rather than bone. This makes them members of the shark family, Elasmobranchii. Unlike true sharks, rays have flattened bodies, and their gill slits are located beneath their heads, which sets them apart from their more famous relatives.
Mostly sedentary, rays tend to live buried or resting on sandy or muddy ocean floors. However, some species, like the majestic manta ray (Manta birostris), are adapted to a pelagic lifestyle, meaning they roam the open waters. This impressive species can reach up to eight meters in width and five meters in length, with a weight exceeding three tons. Despite its enormous size, the manta ray feeds on microscopic plankton and small fish, filtering them through its mouth as it swims.
Interestingly, there is only one family of rays that inhabit freshwater—the Potamotrygonidae, showing just how versatile these creatures can be across different aquatic environments. Whether lying still on the ocean floor or elegantly swimming through the water, the rays of Baía das Raias are a perfect example of the fascinating diversity within the world of marine life.
