Here’s my Halloween contribution (far from horrific though – unless you have a thing about spiders).
Vampire spider craves your blood
The East African jumping spider, Evarcha culicivora, has a taste for blood. It isn’t really a vampire, though, because its mouthparts are unable to pierce skin and sip blood.
Instead, it stalks, pounces on and eats female mosquitoes that have just engorged themselves with a victim’s blood.
The blood-hungry spider is the first predator identified to date that selects its prey based upon what the prey just ate.
