Usually called 'Jaguar God of the Underworld', he has been assumed to be the 'Night Sun' - the shape supposedly taken by the sun (Kinich Ahau) during his nightly journey through the underworld - for reason of having the large eyes and filed incisor that also occur with the sun deity, and of sometimes evincing a k 'in infix.
Incisors are described as needle-like and mandibles as delicate (Nowak, 1999; Balete et al., 2007).
