Hypanus sabinus

Rests buried in the sand in shallow water where people wade.
Do the stingray shuffle. Slide your feet instead of stepping, and it feels you coming and swims off before you ever touch it.
This one is venomous, which means it can put venom into you with a bite or a sting. Never touch it, and never try to move it yourself.
Always ask a grown-up before you touch any animal or plant. If something bites or stings you, tell an adult right away.
