Atelopus chiriquiensis, the Chiriqui harlequin frog

asl.[1]

Description

Atelopus chiriquiensis was a moderately sized toad: males measure 28–34 mm (1.1–1.3 in) in snout–vent length and females 36–49 mm (1.4–1.9 in). Colouring was highly variable and usually different between males and females. They had weakly developed and relatively inconspicuous poison glands scattered over the head and

dorsum; nevertheless, they produced tetrodotoxin and aminoacid analog chiriquitoxin , a potent neurotoxin.[2]

Anatomy

The toad lacks a middle ear and uses other means to transfer sound to the inner ear. The structure responsible for this is the body wall overlying the lung.[4][5][6]

Conservation status

This once locally abundant species has not been seen in Costa Rica since 1996 and is considered extinct in the country. It is also thought to have disappeared from Panama as there are no records since late 1990s. The decline was probably linked to

Habitat loss and introduced trout were also threats.[1] The IUCN Red List now considers Atelopus chiriquiensis extinct.[7]
