Q:

What animal has three eyes?

A:

Quick Answer

The tuatara, a reptile found in New Zealand, has a partial third eye, also known as a parietal eye, on top of its head. This eye has a retina, lens, cornea and nerves, but it isn't used for sight.

Full Answer

Scales grow over the third eye of the tuatara in its first six months. This prevents the eye from being used as a sight organ, but it is still light sensitive. The purpose of the third eye isn't well understood, but it may help the tuatara to regulate its body temperature, absorb ultraviolet radiation for vitamin D synthesis and regulate its circadian rhythm.

    How has a frog adapted to its environment?

    A:

    Different frogs have different adaptations, but generally frogs have eyes on the top of their head for seeing out of the water, a long, sticky tongue for capturing prey such as insects and sensitive skin for absorbing water and oxygen. According to BioWeb ULAW, many frogs such as the Northern Leopard Frog have powerful legs that help them adapt to their environment both by jumping in a zigzag pattern to avoid being eaten on land, and also for swimming skilfully enough to catch their own prey in water.

    How do deer adapt to their environment?

    A:

    Adaptations that help deer survive include being fast and agile, having strong muscles for kicking, cupped ears that pinpoint sounds, eyes on the sides of their heads and sensitive noses that pick up predator scents at 150 yards away or more. Deer have many predators, so their adaptations are largely related to early detection, running away and defending themselves with strong hind legs when cornered.
