虽然懒惰的运动似乎类似于其他哺乳动物，德国动物学家发现，他们的解剖结构有很大不同。他们有very long arms, but very short shoulder blades。这给了他们一个大的范围没有太多的感动，使他们能够节省能源，同时使同样的动作为其他动物。
When you only have one foot, it’s difficult to move very quickly. The common garden snail has a flat, muscular organ that propels it extremely slowly along its purposeful path. To help it move, the snail releases a stream of mucus to reduce friction,reports the Dudley Zoo。这就是为什么你总能看到泥的线索在花园蜗牛的苏醒。一个花园蜗牛的最高速度是每秒1/2英寸（1.3厘米），但它可以为一英寸（0.28厘米）的1/10缓缓移动。
Charles Darwin studied the tortoises when he was on the Galapagos in 1835. He thought they moved relatively quickly. “One large one, I found by pacing, walked at the rate of 60 yards in 10 minutes, or 360 in the hour,” he wrote inZoology Notes。“以这样的步伐，而动物会走四方英里的一天和有短暂的休息时间。”然而，斯蒂芬·布雷克，加拉帕戈斯龟生态运动项目协调员，tells the BBCthat their turtles move a maximum of two kilometers (1.2 miles) per hour, suggesting that "Darwin was probably chasing them."
There’s not a lot of agreement about which animal is the absolute slowest. But University of Eastern Kentucky biologist Branley Allan Branson投票支持香蕉蛞蝓赢得最高荣誉。"A large banana slug has been observed to cover 6.5 inches in 120 minutes,” he wrote. “At that rate, a tortoise would seem fleet-footed."
Are slow lorises really slow? For the most part, the loris is a lollygagger. The animal is mostly deliberate in its actions until it goes after prey. Then it strikes with lightning speed, it stands upright, grabbing a brand with its feet and throws its body forward to nab its prey with both hands,reports Cleveland Metroparks Zoo。
这只小动物可能看起来非常可爱，可爱的，但懒猴是世界上唯一有毒的灵长类动物。毛茸茸的动物有toxins in its mouth从它的肘部一侧的腺体和释放毒素。他们散布在它们的皮毛有毒的组合，以阻止掠食者或之后他们只是去一个致命的一口。
Related to coral and jellyfish, there are1000余个海葵物种around the world. These colorful and interesting underwater creatures use their lone foot — called a pedal disc — and mucus secretions to attach themselves to shells, plants, rocks, or coral reefs. They rarely detach, waiting for fish to get close enough for lunch. But when they do move, theirpace is about a centimeter (.04 inch) per hour。研究人员已经能够捕捉到它们的运动与延时拍摄。他们通常移动响应掠食者或不利条件。
Compared to some of these other animals, the manatee is relatively speedy. But considering their heft and disdain for movement, manatees are usually very slow. The gentle giant of the ocean — also known as the sea cow — can reach up to 13 feet long and weigh as much as 3,500 pounds. With that much heft, it’s no wonder that manatees are rarely in a hurry. Manatees usually move at a speed of only a几英里每小时的。但是，如果他们真的需要的地方，他们可以复苏的步伐，以高达每小时20英里。
海牛通常留在浅水中。他们don't really have any true predators。Sharks or whales could eat them, but because they don't live in the same water, that rarely happens. Their biggest threat is from humans. But thanks to robust conservation efforts, the West Indian manatee in Florida was removed from the endangered species list in 2017.
