Sea urchins are spiny, purple and red. They are in the echinoderm family. They live on the seafloor and they eat kelp. They are slow and lazy. They fight seals and sea lions with their spines. They lay eggs and you can eat them in Sushi!

Scuba diving with Jon Adkins:
Jon's scuba skillsHello my name is Jonathan and I’m going to be discussing how my friends and I got scuba certified.
It all starts with learning the basics. Some of the basics are learning how to use a dive chart. A dive chart is what all scuba divers use to accommodate time spent at certain depth and residual nitrogen in our bodies after each dive and dive plans. We also had to learn safety checks for all equipment, safety rules, buoyancy and more. We had to learn how to do everything in a pool before we went into the water.
It’s important to understand the signs used under water such as the following:
- out of air
- - low on air
- - I’m ok,
- -get over here, etc.
You also need to know your partner’s preferences on equipment, time management, what to do in a emergency, and what you are going to do in your dive plan.
