Stingrays have strong, heavy cartilage dental plates with which they crush their food. Southern stingrays have white underbellies and slate gray, brown, or black upper surfaces. Stingrays bear live young. Like other rays, such as the stingray, eagle rays feed on mollusks and crustaceans. They can reach up to eight feet across the wingspan.
Mantas are dark brown to black.
Mantas have live births and, in all recorded cases, have had only a single embryo. Embryos weigh twenty pounds and measure over fifty inches. Work Outdoors at GORP Jobs Click Here. All rights reserved. Privacy policy .
