You never know who'll drop by DRC, or swim by for that matter.
A staff member having a meeting at the end of the causeway just happened to look up at the right time as this mother manatee and her calf swam up. Apparently, there was some tasty algae growing on the rocks. A yummy manatee snack, perhaps?
After staying long enough for several staff members and guests to ooh, ahh and take pictures, the manatees swam off to their next destination, wherever that might be.
