Description: Fejervarya cancrivora has a SVL of 68.2 mm. The sides of the head have small glandular warts. Parts of the flanks have glandular folds and the lower part has glandular warts. The back has interrupted dorsolateral folds. The dorsal sides of the limbs have warts and folds, while the ventral surfaces are smooth. It has a medium sized, narrow head. The snout is oval. F. cancrivora has a rounded canthus rostralis, a concave loreal region, and a flat interorbital space. The nostrils, which are closer to the tip of the snout than the eye, are oval and have a small flap. The tympanum is distinct. The pupil is rounded. It has a few teeth between the choanae on the vomerine ridge. The tongue is large. It has a supratympanic fold. No parotoid glands are present. The fingers are long and the finger tips are pointed. Some of the fingers have dermal fringes, but have no webbing. Subarticular tubercles are present and are rounded. Toes are long and have webbing and dermal fringes (Dubois and Ohler 2000).
Diagnosis: F. cancrivora can be distinguished from F. limnocharis by having a deeper head and a more pointed beak-like snout (McKay 2006).
Coloration: Color varies from brown, or greenish-brown, to gray, with irregular darker bars scattered on the lips and hindlimbs. The venter is whitish, sometimes with scattered darker markings (McKay 2006).
Coloration in Preservation: The dorsum and flanks are brown with indistinct brown spots. A wide, light brown mid-dorsal band runs from the tip of the snout to the vent. Vocal sacs are dark brown. The belly and undersides are white with light brown spots (Dubois and Ohler 2000).
Variation: Males have nuptial spines on the nuptial pads and vocal sacs are present (Dubois and Ohler 2000). Mature males may or may not have dark throats and thumbs, and sometimes lack slits opening to the vocal sac (McKay 2006).
Tadpole Morphology: Tadpoles have a maximum total length of 40 mm. The body is oval-shaped and dark-colored with dark spots. The tail is less than twice the body length. The spiracle is centered on one side of the body. The mouth is situated under the snout. The upper lip has a single row of papillae and the lower lip has two rows. (McKay 2006).
F. limnocharis is the most closely related to F. cancrivora (Ren et al. 2009).
