菲律賓呂宋島發表了一種新的大頭蛙屬 𝘓𝘪𝘮𝘯𝘰𝘯𝘦𝘤𝘵𝘦𝘴 𝘤𝘢𝘴𝘴𝘪𝘰𝘱𝘦𝘪𝘢。這個新物種過去一直被誤以為呂宋島巨尖牙蛙𝘓𝘪𝘮𝘯𝘰𝘯𝘦𝘤𝘵𝘦𝘴 𝘮𝘢𝘤𝘳𝘰𝘤𝘦𝘱𝘩𝘢𝘭𝘶𝘴的未成年個體。爬蟲學家研究了這兩個物種的許多標本，除了趾盤外，牠們的外觀幾乎相同。新發表的尖牙蛙有無色素的白色腳趾盤，而較大的尖牙蛙則有深灰色而且有色素的腳趾盤。與宋島巨尖牙蛙相比，體型較小的尖牙蛙，雄性在生長過程中會更早形成其特有的大頭及尖牙。

A new species of fanged frog Limnonectes cassiopeia was published in the Philippine island of Luzon. This new species was mistakenly indentified as the juvenile of the Luzon Giant Fanged Frog Limnonectes macrocephalus. Herpetologist studies many specimens of these two species, their physical appearance are almost identical except their toe discs. The new smaller species has unpigmented white toe discs, while the larger one has dark grey pigmented toe discs. Males of the smaller species also develop their characteristic large head and fangs earlier in their growth compare to the larger species.
