A case of bilateral anophthalmy in an adult Boana faber (Anura: Hylidae) from southeastern Brazil

Ocular anomalies in two species of Osteocephalus (Anura: Hylidae) from the Amazonian region of northern Brazil

“…Our reports are anecdotal but add information about the natural history and phenotypic variation of these two species of Osteocephalus. Cases of ocular anomalies are rarely described in the literature (e.g., Ramalho et al 2017, Sousa and Costa-Campos 2017, Brassaloti and Bertoluci 2018, Mônico et al 2019, Pedroso-Santos et al 2020, Souza et al 2021, and to our knowledge, no reports in the literature associate blackeyedness with blindness. Black-eyedness in anurans is related to habitat disruption (e.g., Aráoz 2016, Gurushankara et al 2007).…”

Anophthalmia in Palmate Newts (Lissotriton helveticus) in Galicia (Northwestern Spain)

“…However, Brassaloti and Bertoluci (2018) documented bilateral anophthalmia in a Blacksmith Treefrog (Boana faber) in which no optic nerves were present, indicating abnormal development. Nevertheless, we believe that the most likely cause in both instances was a sublethal injury caused by a predator (Bowerman et al 2010).…”
