10 Laziest Animals on the Earth

Sometimes, you feel like lying on your bed, eating chips, and watching Netflix or Amazon Prime. Other times, you want to sleep. We may experience this for a day or two, but there are animals on our planets who sleep away most of the day. Sleeping is their routine. Without any doubt, these animals are the laziest. Today, we bring you the list of the laziest animals on Earth. Let us begin…

1. Koala

koala - laziest animals

Scientific name: Phascolarctos cinereus

Sleeping time: 18-22 hours a day

It is a herbivorous marsupial. It is native to Australia. You can see a Koala in the coastal regions of the southern and eastern parts of Australia. It resembles a bear, but it is not at all related to it. It has a large head, round fluffy ears, large nose.

The color of the fur varies from silver-grey to chocolate brown. It inhibits eucalyptus woodlands. The eucalyptus leaves form a major part of their diet. You can see a Koala holding on to a eucalyptus branch. It doesn’t have many predators and is not affected by many parasites. Due to hunting and poaching, it is listed under ‘Vulnerable’ in the IUCN Red List.

Its diet is mostly made up of eucalyptus leaves, and hence it doesn’t get enough nutrition and sleeps for 18 to 22 hours a day! In the two hours that it is awake, eating takes up a major portion of the time.

2. Sloth

sloth - laziest animals

Scientific name: Folivora (name of suborder, have six species, and each species have a different scientific name)

It is a group of arboreal mammals. It is seen in the tropical rainforests of Central America and South America. It is closely related to anteaters. Only six species of sloth are present in the world. It is mostly seen hanging upside down a tree.

It mostly depends on the leaves. Some species are omnivores, and other species of sloths are herbivores. It holds the record for the slowest digestion of food among mammals (it can take a month to digest the food). Though it is a warm-blooded animal, it adapts to thermoregulation like a cold-blooded animal because of its slower metabolism.

It can remain motionless for 90% of the day! It sleeps for around 20 hours that too, while hanging from a tree. It is certainly one of the laziest animals and slowest animals on Earth.
