I can relate because Green Iguanas are typically semi-aquatic in the wild and swim in much the same way as crocodilians: side-to-side movements and propulsion from a strong tail. See here: https://youtu.be/9-2YcjsDQ60?t=470

I went swimming at an indoor pool last year and they had a little loop of flowing current, and floating around that on a float board proved a really nice way to invoke "swimming reptile" feelings for me.
