Zombie Fungus

  • About: The zombie fungus, Ophiocordyceps unilateralis, completely drains its host of nutrients.
  • Spore Reproduction: It fills the host’s body with spores, enabling the fungus to reproduce.
  • Mind Control: This fungus takes over the mind and motor functions of its host before consuming its body.
  • Genus: Cordyceps is a genus of fungi that mainly attacks invertebrates, particularly insects like ants and spiders.
  • Pantropical Distribution: The fungus is largely pantropical and predominantly infects carpenter ants.


Tarantulas

  • Classification: Tarantulas are large, hairy spiders that belong to the family Theraphosidae.
  • Global Distribution: With over 900 species, tarantulas are found worldwide except in Antarctica.
  • Nocturnal Predators: They are slow-moving on their eight hairy legs but are effective nocturnal predators.
  • Size and Length: Adult tarantulas typically reach a length of five inches (13 centimeters), with a leg span of up to 11 inches (28 centimeters) when fully spread out.
