They can be identified as opportunistic feeders and continuous foragers, since they exhibit continuous feeding of multiple organisms throughout the day (this helps to explain the stomach contents revealed in the previously mentioned study). The disc of D. americana is diamond-shaped, making it more angular than discs of other rays. The hot water may also draw out venom, which resembles jelly. The tail can be twice as long as the body. Allow the salt water to clean the wound while applying pressure over it to both slow the bleeding and encourage the venom to come out.
