You get taught that animals see different colors. I was reading a book about animal senses and I thought how do we know what some animals see?

Truth is we don’t actually know for sure, we don’t even know if every human experiences sight and colour the same way.

However we can infer based on what we know about eyes from human and animal dissections is that some animals lack cells in the eye we posses. We then infer that due to animals not having the same sets of colour receptors as we do that they see colour differently.
