Basically, photographers take very nice photos for a living. They can be hired to take pictures of something, for instance a family wanting their picture taken. That's where the photographer comes in. So yeah, they take pictures!
There are those photographers and photo studios that specialize only in baby photography and some may go as far as child photography as well. You can usually find listings for baby photography in your local phone book.
I'm unable to provide pictures, but during the Devonian period (around 419-359 million years ago), the Earth was dominated by plants, fish, and early tetrapods. This was an important time for the evolution of vertebrates, with the first evidence of terrestrial life appearing. The Devonian is often referred to as the "Age of Fishes" due to the diverse marine life present during this period.
