So, the part where a couple Faunus girls are swimming and stop to look at Blake...

The girl with a green shirt and no hat is basically a mermaid. Her Faunus trait is that her lower half is the end half of a fish. When she and her friend swim away, you can see where her skin transitions to scales, and you can also see her dorsal fin and just barely see her tail fins.
