Philippine Amphibians Philippine Amphibians 112 or 113 species (Alcala & Brown 1998, 1999; Brown et al. 2000; Diesmos et al. 2004, 2006; Siler et al. 2007, 2009, 2010; Brown et al. 2009) 85% inhabit the forested areas (Brown et al., 2008) 95% endemic to Philippines (Brown et al., 2008) 99 species endemics 45% threatened with extinction (Alcala, et al., 2012; Brown, et al., 2012; Diesmos, et al., 2014). Gymnophiona: Caecilians Caecilians (/sɪˈsɪliən/; New Latin for 'blind ones') are a group of limbless, vermiform (worm-shaped) or serpentine (snake-shaped) amphibians with small or sometimes nonexistent eyes. They mostly live hidden in soil or in streambeds, and this cryptic lifestyle renders caecilians among the least familiar amphibians.

Photographs copyright Tony Gerard (a), Arman N. Pili (b), How to ID your Frogs using Basic Morphology as guide: Mts. Makiling and Banahaw as Guide WEB VERSION WEB VERSION Frogs? 1. Male frogs often have small, differently colored patches on their hands. 2. These patches are particularly noticeable on the insides of their thumbs. 3. The texture of these patches can be rough, aiding in mating. 4. During the breeding season, male frogs often undergo color changes. 5. Their patches may turn dark and become raised, enhancing visibility. 6. Nuptial pads are slightly darker, textured areas on male frogs' thumbs. 7. They assist in gripping the female during mating.
