Both male and female penguins take turns caring for their eggs and chicks.
While swimming, penguins jump out of the water in low arcs (called porpoising). This act coats their feathers in tiny bubbles, which helps reduce friction and allows them to swim faster: up to 20 miles per hour (32 kph)!
A lion’s roar can be heard as far as five miles away.
Goldfish are the only animals that can see in both infrared and ultraviolet light.
Mice are remarkably adaptable to almost any environment, making them one of the most successful mammals living on Earth today.
Mice in the wild are nature’s architects; building intricate burrows that have long entrances equipped with escape tunnels and routes.
Hamsters are generally solitary animals. They are excellent diggers, constructing burrows with one or more entrances. A burrow includes a steep entrance pipe, a nesting chamber, a food-storage chamber, and a branch for urination – in other words, an entrance lobby, a bedroom, a kitchen and a bathroom!
The Galapagos tortoise has a potential life span of over 175 years.
The tuatara is a reptile unique to New Zealand. Tuatara may have the slowest growth rates of any reptile, continuing to grow larger for the first 35 years of their life. Their average lifespan is about 60 years, but they can live to well over 100 years old*.
* Experts believe some tuatara have lived as long as 200 years, but sadly in captive situations.
