Stingray Evolution or creation?

Stingrays are unique marine creatures and cartilaginous fishes that have some similarities to the sharks, but their bodies have a strikingly different shape than the sharks, being known for their flat bodies and long tails. Their sting comes from their tail and this feature is used as a self-defense mechanism. The sting contains venom glands covered by a thin layer of skin. Stingrays are most commonly located in tropical and subtropical marine waters, while some do live in temperate waters and some also can live in freshwater. Most stingrays live near the bottom of the water body but some do live higher in the waters. Their head and eyes extend above their relatively flat, symmetrical body while their mouths are located on the underside of their body. The uniquely designed stingray body allows this creature to hide under the seafloor sediment and to eat what it is laying on. When stingrays settle on the seafloor, they commonly feed at coral-rich areas and feed on molluscs, crustaceans, and other smaller sea creatures.

Evolutionists claim that the stingray evolved from the shark, but it is obvious that the stingray is a uniquely designed creature that was given what it needed to survive in its environment. Evolutionists cannot find a reasonable "evolutionary trail" in the fossil record. So evolutionists call the sting ray a flat shark with a tail, but cannot explain how the shark morphed into this new flatter body figure. In addition, there is one variety of sting ray that has unique blue spots spread on its body and these spots appear to be illuminated, adding to the uniqueness of these creatures. The stingray appeared suddenly in the fossil record with no ancestors, which is exactly what would happen if these creatures were created suddenly at one time a few thousand years ago and there was no evolution over millions of years, just as the creation model explains.
