Shape of Life provides free science resources for both students and teachers about the evolution of the animal kingdom. We offer short videos, lesson plans, features and news of animals on planet earth.
Phyla
The animal kingdom is one of six kingdoms of life on earth. Discover the greatest story ever told - the story of the animal kingdom and the eight major phyla that make up 99 percent of animals.

Lesson Plan
What's The Bigger Picture
In this lesson, students combine art and science to interpret and illustrate graphical art. In this way, students will build understanding of the power of data infused art to convey the "bigger picture" of climate change.

Anchovy Die-Offs
Sometimes very large schools of anchovies come in close to shore and mistakenly swim up harbors where they find a dead end.

Tunicate Evolution and Us
Tunicates are invertebrates without backbones. But in their larval stage they have all four characteristics of chordates: a notochord, which is like a soft spinal cord; a post-anal tail; a dorsal nerve cord; and pharyngeal slits. Their name comes from a thick extracellular covering called a tunic. There are over three thousand species of tunicate living today.
