(Green Anaconda. Photo By John Murphy). A new study by Rivas and colleagues (2024) (link) has revealed that the green anaconda consists of two cryptic species that are genetically distinct. They are the the Northern Green Anaconda (Eunectes akayima s.p nov) and Southern Green Anaconda (Eunectes murinus). For those wondering what species we have in Trinidad, it is Eunectes akayima, the Northern Green Anaconda. Another updated species name for a herpetofauna found in the country. For more information, including distribution of the two species of green anacondas and morphological comparisons, fu ..read more

Anolis lizards are widespread across the Caribbean and continental Americas. In Trinidad and Tobago, there is one confirmed plus one putative native species. All others are introduced species, all from other Caribbean islands. However, a recent discovery by S. George was made of a new lizard species record for the country - the grass anole (Anolis auratus). This species is native to South and Central America. The discovery was published in the local journal Living World, which can be found at the link here ..read more

The Suriname toad (Pipa pipa) is an aquatic frog found across South America and on the island of Trinidad. The last reported documentation of the frog in Trinidad came in the 1990s. In 2023, local naturalists observed the frog in-situ in southern Trinidad. A link to the published natural history note can be found here ..read more

(Lesser dark-spotted thin-toed frog: Adenomera cf hylaedactyla. Photo by Renoir Auguste). || "Community science events like the Bioblitz and platforms like iNaturalist (iNaturalist.org) have great potential for not only educating the public about local wildlife, but increasing scientific knowledge of wildlife distribution". The following natural history note publication is another example of this, as a frog not officially reported for Tobago (but has been for Trinidad), was revealed to not only be present in Tobago, but apparently established as well, given that it was seen at four different ..read more

(Photo: Turpin's frog, Pristimantis turpinorum, mating pair, observed in Tobago. Photograph by Renoir J. Auguste). | A recent study published in the journal Nature has highlighted Ongoing declines for the world's amphibians in the face of emerging threats (link to open access paper here). It highlights 41% of the world's amphibians are threatened with extinction. "Amphibians are the vertebrate class more threatened than any other (more than mammals, birds, reptiles). Among the global threats impacting amphibians, climate change has emerged as one of the primary drivers of declines within the ..read more

Golden Tree Frog (Phytotriades auratus) from Trinidad. Photo by Rick Lehtinen. ||| The golden tree frog is found in Trinidad and Venezuela. It is a species restricted to mountain tops, and lives almost entirely in bromeliads on trees. This frog species is currently considered endangered by the IUCN, and is threatened by climate change and habitat degradation. However, a recent publication by Lehtinen, Borowsky, Auguste, Kosowsky and Richards-Zawacki in Herpetological Review 54(1) 2023 reports that the deadly chytrid fungal pathogen (Bd) was detected in individuals from El Tucuche in Trinidad ..read more

Scorpion mud turtle (Kinosternon scorpioides). Photo by Renoir Auguste. ||| A recent study was published and it assessed nocturnal basking in freshwater turtles from across the world, including surveys from Trinidad and Tobago. An incidental observation of nocturnal basking was recorded with the scorpion mud turtle in an urban area in southern Trinidad which was included in the global assessment. Further, surveys using wildlife cameras took place at Point-a-Pierre Wildfowl Trust to further evaluate whether turtles were basking at night, or only during the day. The only species caught on camer ..read more

A new book has been published "The Conservation and Biogeography of Amphibians in the Caribbean". In it, Chapter 12 features an updated review of the "Amphibians and their conservation in Trinidad and Tobago". The book is edited by Neftali Rios-Lopez and Harold Heatwole, published by Pelagic Publishing. Summary of the book's description: An expansive and detailed review of the biology of Caribbean amphibians, considering their threats, conservation and outlook in a changing world. Amphibians are the group of vertebrates undergoing the fastest rate of extinction; it is urgent that we understan ..read more

(Aripo Savannas Environmentally Sensitive Area, Trinidad. Photo by Renoir Auguste). Currently, there are tree designated Environmentally Sensitive Areas (ESAs) in Trinidad and Tobago: The Aripo Savannas, Matura, and Nariva Swamp. Each comprises a variety of hbitats, from savanna grassland, to wet forests, coastal beaches, and marsh swamps. Because of this, there are a high diversity of amphibians and reptiles. Example of some of the herpetofauna found in these ESAs can be found here and here. For local and international persons interested in seeing native herpetofauna, these three areas are h ..read more

Pristimantis is one of the most species rich genus of animals on Earth. Trinidad and Tobago has three species of frogs in that genus. One is found in Trinidad and Tobago (Urich's litter frog Pristimantis urichi), the other two are found on Tobago only (Charlotteville litter frog P. charlottevillensis, and Turpin's litter frog P. turpinorum). A recent published study (link here) provided updated and novel information on the ecology, conservation status, and genetics of these frogs. Based on the conservation status, the frogs were previously listed as Vulnerable, Least Concern, and Vulnerable, r ..read more
