Essential tools: An SLR camera in an underwater housing (this one is equipped with a 10mm fisheye lens) and a mask and snorkel. Ulloa stationed his mask, snorkel and camera by the water and waited for the clouds to clear in the morning. He needed full sunlight to take the best photos. Once the sun came out, he carefully entered the water to document the last manatees of the morning as they woke up and left the spring.
