The description of the animal vary; and "no one ever saw it well enough to know whether it was a bird or a mammal, whether is had feathers or fur". In Chile some say it moves like a
firefly in the night. In Latin American lore, it is said to hold treasures inside so whoever manages to capture it will become wealthy. An alleged specimen seen in
Ovalle on the Tulahuén hill in
Coquimbo Region, Chile shone bright from the jewel and gold inside it. Or else, such gemlike gleam is supposed to be a guiding beacon to naturally occurring treasures. In
Catamarca Province, Argentina, the
carbunclo is considered an imaginary animal that emits a much light from its head, while many believed the light source to be a carbuncle (gem). In
Tarapacá, it is said to look like a
bivalve with a strong white-blue shine from within the shell which can be observed from a distance 1 league away; this "bivalve" has an acute sense of hearing, so that it can quickly detect humans approaching, and clam up inside its hard shell, and be mistaken for a stone. According to some, it is shaped like a
corncob but is articulated or jointed, and according to a witness who tracked it, it had bluish white light leaking from the joints, and had more than four limbs. It was a creature larger than a mouse but equipped with a hard shell, as crudely described by a certain laborer who was in too much of a hurry to kill it and seize the gold and riches from the shell before attracting the greedy notice of others. It is commented that the man got rich but science suffered the knowledge lost. During the
great drought of 1924–25 there were reported sightings of carbunclos on moonless nights. Around 1925 a family of carbunclos was seen descending from the mountain of Tulahuén towards Río Grande (Coquimbo Region). ==Chilote mythology==
