Overview of Stingrays
The stingrays are a family of rays, which are cartilaginous
fish (fish with cartilage) related to sharks. They are
common in coastal tropical and subtropical marine waters
throughout the world, with some even entirely restricted
to fresh water. However, nearly all sting rays live
on the sandy floors of the bottom of the ocean.
Their primary means of defence is a poisonous barbed
spine located on their tail. They are named after this
barbed stinger, which may reach a length of about a
foot. Some species have several stingers, and some lack
stingers entirely.They have whip-like tails they use
to lash out at prey and predators.
Stingrays have flattened teeth, they use to crush the
shells of crabs and mollusks. The hammerhead shark frequently
preys on stingrays, using its unusually-shaped head
to pin it down.
The flattened bodies of stingrays allow them to effectively
conceal themselves in their environment, underneath
the sand. Due to the placement of their eyes on the
top of their head, and mouth on the bottom, stingrays
cannot see their prey. Instead, they use smell and ampullae
of Lorenzini (to sense electrical fields), like sharks.
They feed primarily on mollusks, crustaceans and small
