Visualizing 40 Different Animal Sleep Patterns

Every animal has to rest in some way, but some animals need a lot more sleep than others.

This graphic by Giulia De Amicis uses data from startsleeping.com to show the typical sleeping patterns of 40 different animals, highlighting their average sleep times, and what percentage of each 24-hour day they spend resting.

Compared to the rest of the animals featured in the graphic, humans need a relatively small amount of sleep. We sleep for an average of eight hours—or 33% of our day.

In contrast, Koalas sleep up to 22 hours a day, or 87.5% of the day. This is mostly because of the Koala’s diet—Koalas eat Eucalyptus leaves, which are toxic and take a lot of energy to digest.

From tropical rainforest nations to the sandy deserts of North Africa and the Middle East, the world’s wettest and driest countries are a study in contrasts.

We map and rank the countries that receive the highest and lowest average annual precipitation in millimeters, per latest data from the World Bank.

Ranked: Top 10 Wettest Countries

Colombia tops the list of nations with the highest average precipitation at 3,240 millimeters (128 inches) in a year.

Its Tutunendo district is the one of the world’s wettest places, averaging nearly 12,000 mm (463 inches) of rain annually.

RankCountryAverage Annual

1Colombia3,240
2Sao Tome & Principe3,200
3Papua New Guinea3,142
4Solomon Islands3,028
5Panama2,928
6Costa Rica2,926
7Samoa2,880
8Malaysia2,875
9Brunei2,722
10Indonesia2,702

Note: Figures are rounded.

Off the coast of Africa however, Sao Tome & Principe is not far behind Colombia, receiving about 3,200 mm of rain in 2020.

Papua New Guinea and the Solomon Islands also average more than 3,000 mm of rain in a year, and Panama (2,928 mm) rounds out the top five.

Noticeably, all 10 countries lie in close proximity to the equator, and near oceans, where rising hot and humid air leads to abundant rainfall.

Ranked: Top 10 Driest Countries

On the other end of the scale, Egypt records the lowest average annual rainfall across all countries, at 18 mm (0.7 inches). For comparison, Colombia receives nearly 180x the amount of rain Egypt does.

4Qatar74
5UAE78
6Bahrain83
7Algeria89
8Mauritania92
9Jordan111
10Kuwait121

Note: Figures are rounded.

In fact, countries from North Africa and the Middle East make up the entirety of this list of the driest countries in the world.
