Cownose Stingray

Cownose Ray

Rhinoptera bonasus

Size: to 3 ft across

Habitat: Coastal

Notes:
Unlike the other fishes on this page, this is a free-swimming ray, often found near shore in large schools. They generally arrive en masse late in the season and are otherwise uncommon.

These rays fly through the upper waters on flapping pectoral fins, sometimes even leaping out of the water, although they feed on mollusks near the bottom. They are a favorite food of sharks.

Cownose Ray

Bullnose Rays are similar, but with protruding rounded snouts. Southern Spotted Eagle Rays are closely related. All retain the stinger of their bottom-dwelling cousins.

There are a variety of choices you can make here, mainly concerning adjustability. High-end second stages come with one, two, or even three adjustments. Some are actually useful, others are pure marketing nonsense. With thick gloves on, you may not even be able to work them in the water. All user-accessible adjustments have a much narrower range of operation than the internal adjustments that a technician can make. My experience is that if a reg is malfunctioning, the user adjustments will be useless to stop it. On the other hand, if you're a gadget person who likes to fiddle with things, some of the adjustments actually can make a noticeable ( although not essential ) difference in breathing. On the theory that extra moving parts are extra failure points, I would avoid adjustable regulators, but that's not really possible anymore. With most manufacturers, the non-adjustable regs are the bottom of the line, and you don't want that, so buy a good reg, and if it has a few useless bells and whistles, live with them.
