has some very slow animals in it.One of the very slowest is the snail.Even the fastest snails are pretty slow.In 1995,Archie the snail took two minutes and twenty seconds to crawl 13 inches(33

length of a mans arm.Three-toed SlothThe three-toed sloth hangs around in trees most of the time.Because it seldom moves,little plants often grow on its fur.A sloth needs about three minutes to crawl the length of two cars.PACIFIC OCEANATLANTIC OCEANSouth AmericaThree-toed Sloth RangeThe many varieties of starfish,or sea stars,live in oceans around the world.Slow and Slower Level I56StarfishSnails

ocean.It lives in very cold water so it must use its energy to stay warm.The Greenland shark is so slow that it looks for sleeping seals and dead whales to eat.The giant yellow and black swallowtail is the largest butterfly in North America.Swallowtail ButterflyThe large swallowtail butterfly flaps its big wings very slowly.It flaps,glides,then flaps again.It only flaps its wings about 300 times a minute.A swallowtail flies about twice as fast as a six-year-old child can walk.North AmericaGreenlandGreenland Shark RangeATLANTIC OCEANEuropeUnited StatesCanadaMexicoATLANTIC OCEANPACIFIC

sound.ManateeManatees are large,gentle ocean mammals that just float around.Sometimes they are called“sea cows.”They like to take their time and munch on sea grass.In an hour of munching and floating,a manatee can go about three miles.There are four types of Manatees living in coastal waters around the world,and all are endangered.The endangered slow loris lives in rainforest areas of Southeast Asia.It usually sleeps during the day and hunts at night.IndonesiaPhilippinesAsiaPACIFIC OCEANINDIAN OCEANSlow Loris RangeSlow and Slower Level I1314Slow LorisThe loris is a careful little
