Can animals understand human language?
There’s not much evidence that our fish or lizard pets understand us. However, dogs respond when we say, “Sit,” or “Stay.” A 2016 study showed that dogs really do understand human speech. This isn’t unique to our canine friends! Potbelly pigs, chimpanzees, and elephants all understand some human language.
Why do dolphins kill babies?

Can a man smell when a woman is ovulating?
A new study shows that when men smell T-shirts worn by women while ovulating, it triggers a surge in the sex hormone testosterone. Researchers say it’s the first study to show that olfactory cues to a woman’s ovulation stimulate a biological response in men that may affect mating behavior.

Do dolphins get their period?
In species that experience estrus, females are generally only receptive to copulation while they are in heat (dolphins are an exception). In the estrous cycles of most placental mammals, if no fertilization takes place, the uterus reabsorbs the endometrium.
Has a dolphin ever killed a person?
This week, a 10-year old British girl was attacked by captive dolphins while on a ‘swimming with dolphins’ experience sold by travel giant TUI. Dolphins at swim-with attractions have been known to seriously hurt humans by butting them. The resulting injuries have included lacerations and broken bones.
