Goliath Birdeater
The heaviest spider in the world, the Goliath birdeater is a massive, hairy tarantula from the South American rainforest whose leg span can rival a dinner plate, though despite its name it primarily hunts insects and other invertebrates rather than birds.

Non-Biting Midge Larva (Bloodworm)
Wriggling through soft bottom mud in dense colonies, the bloodworm gets its striking red color from a specialized blood pigment that lets it survive in oxygen-poor water where few other insects can.

Human Bot Fly
A stout, dark-bodied fly from the American tropics famous for an unusual reproductive trick: it captures a blood-feeding mosquito mid-flight and glues its own eggs to the mosquito's body before releasing it to carry them to a future host. The adult itself is rarely seen, spending most of its short life in shaded forest understory.
