Other Information
Spotted eagle rays do not use sound to communicate, they sense chemical signals in the water using their olfactory system (smell).
Researchers in Bimini, Bahama Islands, tagged 17 individual rays with small sonic transmitters and tracked them for periods of up to 98 consecutive hours. They discovered that the rays' daily activity fell into four phases which were strongly correlated with the tidal cycle.
These four phases are:
a) Rest
b) Commute
c) Feed and socialize
d) Go home

Some interesting facts:
- Spotted Eagle Rays have one of the largest brain to body weight ratios of any fish.
- Spotted Eagle Rays are the only members of their family to have multiple spines on the tail.
- The earliest reference to the native Brazilian name "narinari" from which the scientific species name was drawn appears in a book on the natural history of Brazil written by a French monk and published in 1613.
