2. •Stingrays are a group of rays,
which are cartilaginous
fish related to sharks.
• They are classified in the
suborder of the order and
consist of eight families.

3. 1. Sixgill Stingray
2. Deep Water
Stingray
3. Stingrees
4. Round Rays
5. Whiptail Stingrays
6. River Stingrays
7. Butterfly Rays
8. Eagle Rays.

4. • The flattened bodies of stingrays allow them to effectively
conceal themselves in their environment.
• Stingrays do this by agitating the sand and hiding beneath
it. Because their eyes are on top of their bodies and their
mouths on the undersides, stingrays cannot see their prey;
instead, they use smell and electroreceptors similar to those
of sharks.
• Stingrays feed primarily on small fish. Some stingrays'
mouths contain two powerful, shell-crushing plates, while
other species only have sucking mouthparts. Stingrays
settle on the bottom while feeding, often leaving only their
eyes and tail visible.
• Coral reefs are favorite feeding grounds and are usually
shared with sharks during high tide.

5. • When a male is courting a female, he will follow her closely,
biting at her pectoral disc. He then places one of his two
claspers into her valve.
• Stingrays are ovoviviparous, bearing live young in "litters" of
5 to 13. The female holds the embryos in the womb without a
placenta. Instead, the embryos absorb nutrients from a yolk
sac, and after the sac is depleted, the mother provides
uterine "milk".
• At the Sea Life London Aquarium, two female stingrays have
delivered seven baby stingrays, although the mothers have
not been near a male for two years. "Rays have been known
to store sperm and not give birth until they decide the timing
is right"

6. • A stingray's diet includes small fish, snails, clams, and
shrimp, and some other small sea creatures.
• Stingrays do not aggressively attack humans, though stings
do normally occur if a ray is accidentally stepped on. To
avoid stepping on a stingray in shallow water, the water
should be waded through with a shuffle.
• Rays are edible, and may be caught as food using fishing
lines or spears. Stingray recipes abound throughout the
world, with dried forms of the wings being most common.
For example, in Malaysia and Singapore, stingray is
commonly grilled over charcoal, then served with
spicy sambal sauce, or soysauce

7. • Scientists working in Thailand's Mae Klong River made a
big find an enormous stingray that they think is a
contender for the largest freshwater fish ever
documented by researchers. The ray was caught and
released in about 65 feet (20 meters) of water in the
Amphawa District, about an hour outside in Bangkok on
March 11, 2015.
