* A group of birds is called a flock, a group of cattle is called a herd, but a group of frogs is called an army. (1)
* There are over 5000 frog species in the world. Each one has a unique call, and some frog calls can be heard a mile away. (2)
* The smallest frogs are the Paedophryne dekot and Paedophryne verrucosa from Papua New Guinea, sizing in at only only 9 mm in length. (3)
* Frogs don’t drink water they absorb it through their skin (2)
* The world's largest frog is the Goliath Frog Conraua goliath, which lives in western Africa. They can grow to be over 30 cm (1 ft) long, and weigh over 3 kg (6.6 lbs - about as much as a newborn baby)! This species is endangered, due to conversion of rainforests into farmland, and due to their being used as a local food source. (3)
* A frog completely sheds its skin about once a week. After it pulls off the old, dead skin, the frog usually eats it. (1)
* Frogs have both a common name and a scientific name, which is in Latin. Thus the African Clawed Frog is also known as Xenopus laevis. The scientific name consists of a frog's genus followed by its species (this is called binomial nomenclature). Carl Linnaeus devised this system in the 18th century so that scientists could be certain they were always referring to the correct species. For instance, there is a 'Green Treefrog' in Europe, America and Australia, but they are all different species: Hyla arborea, Hyla cinerea and Litoria caerulea. (3)
* Frogs are amphibians, which comes from the Greek language and means "both lives." Most frogs are born in water as tadpoles and gradually change into frogs although some frogs, known as direct developers, are born as full frogs. This allows them to be born and live far away from water, such as on mountaintops. (4)
* There is a frog in Indonesia that has no lungs – it breathes entirely through its skin. (1)
* Frogs are known as indicator species and can give scientists valuable insight into how an ecosystem is functioning. Because they are predators and prey many animals are affected by them, frogs provide insight into the health of the ecosystem. (4)
* Some frogs remain in the tadpole stage for 2 or 3 years. (3)
* The Moche people of ancient Peru worshipped animals, and often depicted frogs in their art. (5)
* When a frog swallows its prey, it blinks, which pushes its eyeballs down on top of the mouth to help push the food down its throat. (1)
* The Latin word for a frog (rana) is imitative of croaking. (6)
* One way to tell a male frog from a female frog is by looking at its ears. The ears can be found right behind the frog’s eyes. If the ears are as big as the eyes, then the frog is a boy. If the ears are smaller than the frog’s eyes, then the frog is a girl. (7)
* Some frogs can jump over 20 times their own body length; that is like a human jumping 30m. (2)
June 2015: When I saw that Bookworks in Albuquerque, NM was hosting a Big on Animals! event featuring frogs, of course I had to attend. The lovely ladies from the NM Natural History Museum were great ... and I got to hold a frog!
I also got to meet the adorable Catherine, who had so much fun playing with the frogs. Reminds me of a certain Princess. ;)
May 2015: In the NDI New Mexico show, "Rollin' on the Rio," the dance performed by children from Adobe Acres Elementary School included many, many adorable tree frogs. Princess Cassandra would have loved to meet so many talented frogs! Thank you, Adobe Acres and NDI New Mexico for taking time backstage to help me celebrate my upcoming picture book!
