Lizards feast on leaves

This fellow resembles some lizards I saw at Playa Guiones. They were about 18 inches long and had grey stripes across their backs.
One was in a small tree, hanging heavily from a thin branch by a long claw and using the fronds of a young palm for extra support while he reached ever further out the branch to grab the succulent leaves and devour them.
Another passed by my foot, slightly brushing it, while I sat in a wicker chair by the pool, reading. He paused as I looked down, swung his unlovely head back and forth as if to sniff the wind and waddled off, clumsy but fast, tail swinging back and forth to counterbalance the swaying head.
