Ryan Photographic - Dasyatidae - Whiptail stingrays
Family Dasyatidae
The family Dasyatidae contains around 69 species in 28 genera. Apart from one species they all possess one or more venomous barbs which they use for defense.
They feed on bottom living invertebrates which they suck up with their ventral mouth. These rays will often partially bury themselves in the sand and occasionally get stepped on by a fisherman or incautious swimmer which may lead to a painful evenomation. I am proud to report that I have yet to be stung by a stingray.
All the dasyatid stingrays give birth to live young. They are widely distributed in the world's ocean and some live in estuaries, rivers and lakes. One of these species, Urogymnus polylepis, is considered to be amongst the largest freshwater "fishes".
