Stingrays are considered to be vertebrates, as they are classified as cartilaginous fish. Other fish classifications that are vertebrates include bony fish and jawless fish.
Stingrays are typically found in temperate waters. As of 2014, stingrays are considered to be a threatened species. Stingrays may reach a length of 6.5 feet and can weigh almost 800 pounds. These fish are related to sharks, another type of vertebrate, and have the same electrical sensors to help them locate prey. Stingrays need this kind of detection because their eyes are on top of their flat body, making it difficult to readily notice food that is nearby.
