The BBC’s Rebecca Morelle has published a great piece about the biodiversity of frogs found in the Costa Rican rainforest. What makes the piece great is the the videos of scientists holding the various frogs and explaining what makes each one unique from another. I couldn’t embed the videos here so I linked the image below to the story.
