Observing fish

Image illustrating potential difficulties with classifying fish

This image illustrates the potential difficulties with classifying fish. 

The two fish at the top left are both blue cod but they are at different stages in their lifespan. Some species, such as the banded wrasse (the two images at the top right) can vary in colour. Observation is also impacted by factors such as lighting as shown in the bottom two images, which are both of a scarlet wrasse.
