| Sumario: | A review and update to the shark and ray species recorded for the
marine waters of Colombia was carried out. A total of 206 species
had been recorded in the literature, of which 138 species (76 sharks
and 62 rays) could be confirmed from museum records, catches,
photographs, and videos. No evidence was found for 25 species,
but their distribution included neighboring countries, and they
were therefore classified as possible based on distribution. Thirtysix species were classified as improbable based on distribution and
seven more were considered as misidentifications. The inventory
of confirmed species includes 57 genera (30 shark and 27 batoid
genera) and 34 families (18 shark and 16 batoid families). There
was notably an addition of 26 confirmed species since 2007
as well as numerous modifications to group systematics and
taxonomy, especially for batoids. The total number of confirmed
elasmobranchs represented 12.1% of species known worldwide,
and could even reach 14.5%, indicating that Colombia has one
of the richest cartilaginous fish faunas in Latin America, behind
Mexico and Brazil. This demonstrates that although Colombia
cannot be considered an elasmobranch biodiversity hotspot
or site of elasmobranch endemism globally, it does have good
representativity of these species´ biodiversity at the regional level,
especially regarding amphi-American species.
