Narrow-Necked Cave Beetle
The first cave-dwelling animal ever scientifically described, in 1832. Completely eyeless and unpigmented, with an elongated neck-like pronotum adapted to cave life.
Did You Know?
Described in 1832, this was the first troglobite ever known to science — its discovery launched the entire field of cave biology and biospeleology.
Horse Stomach Bot Fly
A bee-like fly that glues eggs to horse leg hairs where they are ingested during grooming. Larvae attach to the stomach lining and develop for months before passing out.
Did You Know?
Larvae survive the acidic horse stomach by secreting a protective alkaline buffer around themselves.
