• Aphonopelma marxi

  Grand Canyon Black Tarantula

  Aphonopelma marxi is a North American tarantula species in the family Theraphosidae, commonly known as the Grand Canyon Black Tarantula. It is a medium-sized, dark-colored species belonging to the 'Marxi species group' of mainly black, high-elevation tarantulas. The species was first described in 1891 and has undergone taxonomic revision, with two former species (A. behlei and A. vogelae) now recognized as synonyms. It is widely distributed but difficult to observe due to its fossorial habits.
