“…Although Mitsukurina owstoni Jordan 1898 has not yet been reported from the VEEZ, it has been recorded from the Colombian Caribbean (Grijalba‐Bendeck & Acevedo, ) and off French Guiana (Uyeno & Sasaki, ), thereby indicating that the species probably also occurs in the VEEZ. Despite having been recorded from off Guyana by Quéro (; cited by Stevens & Paxton, ), this record apparently refers to French Guiana instead as Quéro () indicated “Maroni (Guyane)” as catch location, which actually is a river that forms the border between French Guiana and Suriname.…”

Using the last taxonomic review of chondrichthyans of the world, we selected the species distributed in the north-western Atlantic Ocean (NWA) and compared it with the available published literature related to the class Chondrichthyes in the Venezuelan exclusive economic zone. We also revised information from worldwide databases such as: FAO (NWA-31 area), GBIF, iSpecies, IUCN and OBIS, as well as available museum collection databases. The taxonomic validity was checked using the Catalogue of Fishes of the California Academy of Sciences and recent references. The past published Venezuelan lists of chondrichthyans combined included nine orders, 30 families and 108 species. The updated list with 12 orders, 36 families and 122 species increased by three new orders, six families, three shark genera, nine shark species (one replacing another species), one chimaera genus, two chimaera species, three batoid genera and six batoid species (two replacing other species). Four holotype specimens (two sharks and two rays) are deposited in Venezuelan Museums. Most of the species have an IUCN conservation status, including four species catalogued as Critically Endangered, six as Endangered and 18 species as Vulnerable. Deepsea fisheries, scientific exploration and taxonomic/genetic revisions might add future increments to the Venezuelan chondrichthyan list.

“…Colleagues at various institutions in Colombia provided elasmobranchs occurrence data from the Caribbean and Pacific areas. Additionally, new species occurrences and range expansions were included from published literature (Nieto et al 2003, Rubio et al 2005, Navia et al 2006, Grijalba-Bendeck & Acevedo 2009, Mejía-Falla & Navia 2009, Payán et al 2010, Gámez-Barrera et al 2012, Acero et al 2016Anguila et al 2016a, b). The taxonomy and systematics of each record used in our database, based on the Eschmeyer's Catalog of Fishes (Fricke et al 2020), was verified and updated as necessary.…”

An analysis on the species richness distribution of marine sharks and batoids for the Colombian Caribbean and Pacific regions was carried out. A total of 138 species was documented in nearby marine waters off Colombia, including 76 sharks and 62 batoids; 20 species occurred on both coasts with the Caribbean generally having a higher observed richness than the Pacific. The Caribbean had high richness values both in the insular as well as in the northern region. However, the highest richness values per spatial unit in the Pacific islands of Gorgona and Malpelo, with completeness richness estimate represented mostly by values below 90%. Richness estimators showed values higher than the observed richness, indicating that the inventories and the description of marine shark and batoid richness in Colombia are still incomplete. Despite this, the results of this study are relevant to make decisions aimed at the conservation of this taxonomic group, both in marine protected and unprotected areas of the Pacific and Caribbean coasts of Colombia

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. Thirty-six 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.

Mitsukurina Owstoni Jordan (Chondrichthyes: Mitsukurinidae) RST Record for the Colombian Caribbean

Abstract: This paper collects bibliographic information about the Goblin shark, Mitsukurina owstoni (Chondrichthyes: Mitsukurinidae), an uncommon shark from deeper waters. One specimen of this species was captured near Nenguange bay and it is recorded for rst time in the Colombian Caribbbean.
