WTF Fun Fact 12943 – A Conspiracy of Lemurs

Lemurs are fascinating creatures. They’re also diverse – there are 113 types of lemur, all native to Madagascar. Lemurs are social creatures that are active during the day and live in groups of up to 30. These groups are called a conspiracy of lemurs (or alternately a troop).

Why is it called a conspiracy of lemurs?

According to LiveScience (cited below), “Lemurs’ main predators are fossas (Cryptoprocta ferox) — carnivores that looks a bit like a cat or weasel. Lemurs can also become prey for large snakes, birds, humans and animals humans have introduced to Madagascar, such as domestic cats.”

By living in groups, it’s easier for lemurs to alert each other to dangers. The reason a group of lemurs is also called a “conspiracy” is that they work together (or conspire) to outsmart predators and stay safe.

Unfortunately, they can’t conspire to stop habitat destruction. “In 2020, the IUCN(opens in new tab) announced that 98% of all lemurs are threatened with extinction. The main reasons lemur populations have declined so significantly is because of habitat loss due to deforestation(opens in new tab) and hunting in Madagascar. Their habitat is often destroyed so that it can be used for agriculture, and they are hunted for food,” reports LiveScience.

Lemur mobbing

After conspiring to outsmart the predators they have some control over, lemurs also use a technique called “mobbing” to attack predators all at once.

Lemurs can jump up to six times their body length, so they presumably seem like they come out of nowhere and predators hardly get a chance to know what hit them (literally – conspiracies of lemurs have been known to beat large snakes to death).

Cooperative attacking and harassing (aka mobbing) is not limited to lemurs. Many species use this technique to eliminate the threat of predators.

These furry creatures seem to have quite a few sophisticated anti-predator behaviors. — WTF fun facts

WTF Fun Fact 12942 – You Can Hear Rhubarb Growing

When we plant something, it feels like it takes forever to start growing. But that’s not the case with rhubarb. Once this vegetable gets going, it can develop so fast you can hear rhubarb growing.

How to hear rhubarb growing

According to Atlas Obscura (cited below), this is mostly the case with forced rhubarb – the kind you give a little extra effort to in order to get it to develop faster.

“Forced rhubarb, which is made to mature in near total darkness, grows at such an alarming rate—as much as an inch a day—that it actually makes squeaks, creaks, and pops as it gets bigger. It makes for sweeter rhubarb, growers say, and sick beats.”

Of course, if you’re forcing rhubarb to grow in a facility, it can be hard to hear over the sound of any machines you have running to keep the conditions ideal.

Rhubarb’s unique growing characteristics

Atlas Obscura states that “The method of growing forced rhubarb dates back to the early 1800s, and continues in much the same way today. Farmers let the rhubarb grow out in the open for two years, as the roots collect and store calories. Then the plants are transplanted to lightless growing sheds around November, where they continue to grow—warm, but out of season and in the dark. The rhubarb grows without photosynthesis, which normally makes the plant tough and fibrous…The process also results in deep, red stalks, without the normal green shading.”

The loudest noise you’ll hear is the forced rhubarb bursting out of its bud with a pop. Then, it makes a fainter noise as the stalks rub up against each other and squeak. That’s because forced rhubarb isn’t planted far apart.

There aren’t many forced rhubarb growers anymore, though you can still find some in Michigan and Washington state if you want to hear a vegetable grow. — WTF fun facts
