Stingrays reproduce using internal fertilization. They are known to give life birth in the ocean to many infant stingrays at a time.
Stingrays do not have external ears like humans; instead, they have internal ears that are capable of sensing sound vibrations. These internal structures help them detect sounds in their underwater environment, which is crucial for hunting and avoiding predators. Their ability to sense vibrations and pressure changes in the water compensates for the lack of visible ears.
