50 Insane Animal Facts That Will Leave You Asking WTF

21Deathwatch Beetles

Deathwatch beetles start their life as a pupa emerging from an egg and eat wood for 10 to 15 years, at the end of which they emerge as an adult beetle. At this point, they are blind and have less than a week to find a mate and have sex. So the male starts banging his head against the wood and hopes for a female to answer his calls. If he is lucky and finds a female, there are chances that she may reject him.


22Crab Hacker Barnacle

Crab hacker barnacle is a species of barnacle that is a parasite found in crabs. The female will attack a crab, movie inside it, push out a sac that contains its eggs. It then controls the mind of the crab into caring for its egg sack as its own, and when the time comes the crab shoots them out through pulses creating a large cloud of parasites.


23Parasitic Fungus

The ophiocordyceps unilateralis is a parasitical fungus that infects and exerts mind-control over certain species of ants. It will hijack an ant’s central nervous system and force the ant to climb a stalk of vegetation and anchor itself. The fungus then sprouts a stalk from the ant’s head, releasing spores that infect ants below. It can destroy entire ant colonies. In response, ants have evolved the ability to sense that a member of the colony is infected. Healthy ants will then carry the dying one far away from the colony in order to avoid the fungal spore exposure.


24Giraffe

The Humr people of Sudan consume a hallucinogenic drink; which is created from the liver and marrow of giraffes.
