Sloths are arborealfolivores —tree-dwelling animals that eat mostly “buds, tender shoots, and leaves, mainly of Cecropia trees.” They are well-known for moving slowly, and are native to Central and South America.
In honor of International Sloth Day on October 20, National Aquarium will launch a naming contest for the Linne’s two-toed sloth born in Baltimore in late August (2012). The newest addition to the Upland Tropical Rain Forest and the first born to Ivy, one of the four sloths in the exhibit, is the third sloth born at National Aquarium, Baltimore.
The public is invited to visit www.aqua.org/slothcontest between now and November 1 to submit name suggestions. A panel of National Aquarium staff will review and consider all entries. Then, from November 2 to 15, the public can vote on one of four names selected by the panel. The winning name will be announced on the morning of November 16.
