Oedipina maritima, commonly known as the maritime worm salamander, is a species of salamander in the family Plethodontidae. It is endemic to Isla Escudo de Veraguas, Panama. [3]

Description

Oedipina maritima is a small salamander species: males grow to a snout–vent length (SVL) of 40–46 mm (1.6–1.8 in) and females to 35–44 mm (1.4–1.7 in). The head is small and narrow, and the body is slender, with tail longer than SVL. [2]

The clutch size is about six eggs. They have direct development: eggs hatch into juveniles that measure about 12 mm (0.47 in) in total length, still retaining their gills. [2]

Range and habitat

This species is known only from Isla Escudo de Veraguas in Bocas del Toro Province, Panama. [3] If it is restricted to this island (there is a juvenile specimen from the mainland that may belong to this species), it is the only tropical salamander that is endemic to an island. [2] It is found close to sea level in humid lowland forest and mangrove forest. [1] The type series was found in decaying fronds and associated moist litter near a fallen palm in a coconut palm grove. [2]

It is threatened by habitat loss (forest clearance). [1]

The arboreal salamander is a species of climbing salamander. An insectivore, it is native to California and Baja California, where it is primarily associated with oak and sycamore woodlands, and thick chaparral.

Oedipina complex, commonly known as the Gamboa worm salamander, is a species of lungless salamander found in western South America from Costa Rica to western Colombia and north-western Ecuador. This species inhabits humid tropical lowland forest where it can be found on the ground, and on bushy vegetation, logs and rocks. It can also be found on forest edges, but it does not survive in degraded areas. Deforestation is a threat to this species.

Pygmy three-toed sloth A species of mammals related to anteaters and armadillos

The pygmy three-toed sloth, also known as the monk sloth or dwarf sloth, is a sloth endemic to Isla Escudo de Veraguas, a small island off the coast of Panama. The species was first described by Robert P. Anderson of the University of Kansas and Charles O. Handley Jr., of the Smithsonian Institution in 2001. The pygmy three-toed sloth is significantly smaller than the other three members of its genus, but otherwise resembles the brown-throated three-toed sloth. According to Anderson and Handley Jr., the head-and-body length is between 48 and 53 centimetres, and the body mass ranges from 2.5 to 3.5 kg.

Isla Escudo de Veraguas

Isla Escudo de Veraguas is a small (4.3 km2) isolated Caribbean island of the Republic of Panama. Despite its name, it is not part of the province of Veraguas, but rather Bocas del Toro. Although located only 17 km from the coastline in the Golfo de los Mosquitos and isolated for only about 9000 years, several animals found on the island are distinct from their mainland counterparts, and two mammal species or subspecies are recognized as occurring only on the island: the fruit bat Dermanura watsoni incomitata and the sloth Bradypus pygmaeus. These two taxa and the worm salamander Oedipina maritima are all considered to be critically endangered due to their being unique to the small island. Other mammals found on the island include the bats Glossophaga soricina, Micronycteris megalotis, Carollia brevicauda, Myotis riparius, and Saccopteryx leptura, the spiny rat Hoplomys gymnurus, and the opossum Caluromys derbianus. The island has 26.36 acres (10.67 ha) of mangrove forest and 247 acres (100 ha) of coral reef with 55 coral species. It houses over 11,000 species, such as the pygmy sloth. And has an average high of 23 degrees Celsius and a low of 12 degrees Celsius.

The San Gil climbing salamander, also known as the San Gil mushroomtongue salamander, is a species of salamander belonging to the family Plethodontidae. It is endemic to Colombia, and its natural habitats are tropical highly humid forests; it has also been reported from a coffee plantation. The greatest threat posed to this species is habitat loss, however they are currently nowhere near the risk of extinction. The species' name honors Antoine Rouhaire, a French naturalist who collected the species holotype.
