Had a great guided tour around the protected Anaga park.

The guide explained a lot of species of plants.
I have to search for many of them because at the moment I'm not sure about the species.
I hope you can help me.

A juvenile specimen
An example of mimicry. This young sole mimics a poisonous flatworm Pseudoceros scintillatus to protect itself from predators. I spent some minutes on observing it: not only the patterns, even its movement resembled a marine flatworm - undulating with its fins staying close to the bottom.
