The animal kingdom is full of weird stuff, like animals that turn into zombies—and one thing many of them will do is go to great (and gross) lengths to avoid predators.
Armored crickets, which are native to Namibia, South Africa, and Botswana, have a particularly disgusting means of driving away predators: They spew vomit and spurt hemolymph (the mollusk and arthropod version of blood) from under their legs and through slits in their exoskeleton. Katydids do it too; in fact, in Germany the species has acquired the nickname “blutspritzer,” or “blood squirter.”
But that’s not all. Wounded crickets can attract other crickets foraging for protein and salt—and the healthy crickets are happy to become cannibals. According to BBC:
“When swarms [of crickets] in the African bush meet a road, lots get squashed and the others gather for a feast, so more get squashed until there can be a thick, acrid pancake of dead and moribund crickets on the roadside, bleeding and attracting more cannibals,” says [entomologist Bill] Bateman.
The Regal Horned Lizard, too, uses the blood-spewing tactic, shooting the substance from a pocket near its eyes…straight at its attacker’s eyes and mouth.
Check out this video of the lizard shooting blood. (Caution: It’s graphic, as videos of animals spurting blood are wont to be).
