A peek at my personal life! I held a sea urchin today in developmental biology lab 🔬! So cool! 😄I was nervous, but it wasn't sharp and didn't hurt. They move their spines to crawl and have beaks on the bottom😱We also injected them with potassium chloride to stimulate gamete (egg/sperm) spawning so we could see them in a microscope. And yes, I have really long fingers haha. #lifeofbiologymajor #seaurchin by vspink_hauls http://bit.ly/15GCb79
