Despite having the underwhelming name the `common wall lizard', this lizard sports some amazing colours on its underside. Although its back is a boring brown colour, presumably to be less visible to predators, the males have some fabulous colours on their bellies, as well as UV-blue patches down their sides (sadly not visible to us).
When you read the word `communication', you probably think of language in some form, likely spoken or written. This is because, as humans, we're obsessed with communicating through language; it's likely that an hour doesn’t go by in your day when you don't communicate with someone by phone, email or text.
Mice, like us, are social animals. As social animals they like to hang out with each other. Also like us, they don't just hang out with anyone.
