Scientists have determined that the way an animal rests — reclining on its back , sprawl on its belly , standing up , or sitting , is determined by primarily by its size . But more importantly , the report authors have provided a large option of images of animal luxuriating in various shipway , and they are delicious .
scientist agree that rest is crucial , either for “ physical recuperation ” or for the central anxious organisation , according to the newspaper published in the Journal of Mammalogy . But why do animals recumb in the agency that they do ? former hypotheses put forward that the shape and location of the animate being ’s digestive system influences the position in which they unwind . The team behind the newest workplace receive that the narration was more complex than that . They also took a gang of pictures of zoological garden animals just get a genuine laid-back metre .
The researchers notice 253 animals just chillin ’ at menagerie in Germany and Switzerland during the morning , afternoon , and even . They recorded the fauna standing , sitting , lounging on their spine , flopping on their position , and lying on their bellies . They compared differences in resting location to the beast ’ digestive types and other data point , like their hatful .
What did they observe ? Well , kangaroos always rested on their side . Peccaries ( a pig - like mammal ) never laid on their side . Hippos would sometimes slump on their sides , but not more than they ’d lie belly - down . ruminant , animals that ferment food in one venter before digesting it in another ( called chewing their wad ) , never lazed on their sides , since they need to position their digestive tracts the right way . elephant did n’t consist down during the day , but slumber on their sides at nighttime . warthog relax in a sitting posture .
As for pattern , the researchers noticed that declamatory metal money in the main spent more clip standing while rest , and smaller species spend more clock time sitting while resting . Larger animal were also more potential to tip on their side when they did rest down .
In short , they determine that while digestion seems to be a agent in why ruminants do n’t lie on their face , it appear that there are other factors , as well . But again , most importantly , they take away a lot of photos of loafing animals which I would now like to share with you .
hear , I would n’t say I ’m the most pro - zoo mortal in the worldly concern , but I much appreciate the scientific greatest collision of lounging fauna .
