Rachelle Cracchiolo started the company with a friend and fellow teacher. Both were eager to share their ideas and passion for education with other classroom leaders. What began as a hobby, selling lesson plans to local stores, became a part-time job after a full day of teaching, and eventually blossomed into Teacher Created Materials. The story continued in 2004 with the launch of Shell Education and the introduction of professional resources and classroom application books designed to support Teacher Created Materials curriculum resources. Today, Teacher Created Materials and Shell Education are two of the most recognized names in educational publishing around the world.
If an anteater and an armadillo had a baby, it might look something like the pangolin, an odd-looking mammal found throughout parts of Asia and Africa. The pangolin has a long, specially adapted tongue for eating ants and termites and wears a protective keratin shell — it is the only mammal known to have this adaptation. Sadly, its unique characteristics also make it the most trafficked mammal in the world, as it is highly sought-after for its meat and armor. The pangolin is currently listed as a threatened species.
Also known as the Thorny Devil, this lizard has a body covered with thousands of spikes. These spikes are thought to make predators think twice before attempting to swallow a thorny devil. Not only does their spiny armor protect them from predators, it also helps them absorb water in their arid habitat. There are hygroscopic (moisure-attracting) grooves between their thorns. They obtain water from the dew that condenses on their bodies overnight, during rare rainfalls, or by brushing up against dew-coated grass. Any water that gets into the grooves between its thorns is drawn by capillary action to its mouth, allowing the thorny dragon to suck water from all over its body.

Right away this video is suspicious just from the description -- a ghost hanging around the Haunted Mansion at Disneyland? That's a fake haunted house. Why would any realm-shambling specter waste its time in a place where people are expecting to see automated rocking chairs and Muppets dressed up like phantoms? It just seems like that would be super boring.

The Mutillidae are a family of more than 3,000 species of wasps (despite the names) whose wingless females resemble large, hairy ants. Found in Chile, they are known for their extremely painful stings, hence the common name cow killer or cow ant. Black and white specimens are sometimes known as panda ants due to their hair coloration resembling that of the Chinese giant panda. (Image credits: Chris Lukhaup)
