My 9-year-old grandson loves reptiles. He’s fascinated so much he takes pictures of all of them at the Los Angeles Zoo, every single time he visits, to the exasperation of his younger sister. It’s no surprise then that he wanted to go through the reptile (and amphibian) exhibit when my wife and I took both our grandkids to the San Diego Zoo recently. I find frogs more interesting if for no other reason than their extraterrestrial appearance. I saw this pair that look straight out of a sci-fi movie. I failed to note what they were called.
Update: the San Diego Zoo was kind enough to answer by email inquiry. This frog is commonly known as White’s Tree Frog, otherwise known as Litoria caerulea.
