Are you interested in weird and mysterious creatures? This is an excellent piece chock full of creatures that I had never heard of. All of this cryptobiology could give you palpitations! The above, for example, is the minhocao (big earthworm in Portuguese), which is said to burrow underground, is believed to be a relic of the dinosaur age. Sightings were mostly reported in Brazil during the 19th century. Some people think that minhocaos are still spotted but accidentally reported as another cryptid, the giant anaconda.
