Shark Life Cycle Spinner

It’s Shark Week over on the Discovery Channel, so I had to share a fun little shark activity with you, of course! I made a shark life cycle spinner printable for you to use for all of your shark teaching needs. This features a catshark and has it as an adult, a baby and in the mermaid purse (egg case).
This is a simple thing to assemble and I made it in both color and black and white. You just print out the shark life cycle spinner pages, cut them out and assemble with a metal brad fastener.
Teach kids more about the mermaid purse when you make these. It is the case that surrounds the fertilized eggs of the sharks. They are made of collagen (protein). They have curly strands on them that attach to plants to keep them from moving. They take more than a year to hatch, and some sharks hold on to them for a few months until it is closer to hatching time. Once the sharks hatch, these mermaid purses often wash up onto beaches. It is a fun find if you are a beach comber.
Also, have fun learning about catsharks. They are ground sharks and are one of the largest families- there are more than 160 species. But, very small sharks growing to about 31 inches (80 cm). They are not harmful to people and eat mostly small fish and invertebrates- things found along the bottom of the ocean floor. They are nocturnal and have cat-like eyes. They are found in temperate and tropical areas worldwide.
