flat bodies and broad pectoral fins. The main difference between these two groups of fish is their proportions. Skates' discs (heads and body combined) are longer than they are wide, and rays' discs are wider than they are long.
How do we know?
Scientists categorise rays into families based on certain characteristics.
These include the number of dorsal and tail fins they have, and the shape of their discs.
Sometimes scientists disagree on which families a ray should be placed in, or which charateristics should be used to categorise them.
RAY FACTS
Electric Rays can produce an electric charge up to 220 volts to stun or kill the prey, or to protect
from predators....
