Hi, we are Lassie and Piloto. We are a male and a female dogs, and the parents of Barry, the main hero of this educational site and of the children's book BARRY'S ADVENTURE. As we are a male and a female, we'd like to introduce you to animal males and females.

We all know the obvious examples like cow and bull, mare and stallion, or hen and rooster, but what about less common animals? For example, how do you differentiate between a male and female crocodile, falcon or jellyfish? If you’d like to find out the correct male and female names for these animals and many more, then enjoy the game below.

The first two columns on the left show the name of the animal and its male name; the female names are on the right. Put before each female name the number of the matching male.
