Here are the two different kinds of iguanas. One is a marine iguana and the other is a land. Which do you think is which?

My mom almost peed her pants yesterday when she was tide pooling and stepped witin a foot of one and it hissed at her. Then on another day Noelle and I were in the water swimming. From shore my mom saw one swimming directly at us. She said she couldn't decide between warning us or watching for a good laugh. She choose the later and is still laughing when she thinks about it. It swam to within 2 feet of us. Noelle saw it first and started flapping her arms. I couldn't figure out why she was acting like she wanted to fly. Then I saw it and let out a piercing scream. Noelle and I stood there hugging each other and frozen. The igauna turned and swam away. My mom dropped to the ground and rolled with laughter. Some great protective mom. Oh the one on the sand is the Marine iguana.
