The caudal fins are clear with brown dashes on the proximal edges of the anterior half of the dorsal and ventral fins. The larval caudal musculature is a light gray brown. The sides of the body are bluish gray, and the venter is light blue-gray with a silvery cast. Tadpoles have a heavily pigmented snout, top of head, and body, appearing grayish brown. The spiracle is ventral and sinistral to the midline (Duellman 2001). Papillae border the mouth in two rows and laterally scattered small papillae lie medially to the fringing row. The mouth is located anteroventrally and directed anteriorly. The oral disc is small and entire, with large, serrated beaks and 2/3 rows of denticles. The tail is moderate, caudal fins are high and the tail tips are short. The eyes are dorsolateral and directed laterally and the nostrils are dorsolateral and directed anterolaterally. Larvae are moderately sized and have a total length of 33 mm at stage 31. Metamorphs lack blue coloring and turn reddish brown at night and in preservative (Savage 2002). This species is able to undergo metachrosis (color change), and the colors darken at night to a darker green and bluish purple. There are vivid creamy yellow stripes along the ventrolateral margin of the forearm, tarsus and foot. The upper surface of the hands and feet are green, orange, and blue.

The flanks and anterior and posterior thigh surfaces are blue. In contrast to the uniform green upper surfaces, the proximal dorsal portion of the upper arm is pink to lavender and the distal portion is blue. The vocal sac is unpaired, median, subgular and not markedly distensible (Duellman 2001). There is a brown nuptial pad on the base of the thumb in adult males (Savage 2002). The webbing formula for the toes is: I 2-2+ II 1½-3 III 1½-2½ IV 2+ -1½ V. The webbing formula for the fingers is: I 2-2½ II 1½-3- III 2-2 IV. Fingers are about 2/3 webbed and toes are about ¾ webbed (Duellman 2001). The toes are somewhat slim and the terminal discs are only slightly smaller than those on the hand. The diameter of the disc on the third finger is equal to that of the tympanum. The upper arm is slim and the forearm robust, while the hind limb is slender. Another thin dermal fold is present from the heel along the ventrolateral edge of the tarsus to the fifth toe. A weak tarsal fold is observed along the entire length of the tarsus. A narrow dermal fold also extends from the elbow along the ventrolateral edge of the forearm onto the base of the fourth finger. This fold extends from the posterior corner of the orbit to a point posterior to the angle of the jaw. The tympanum is distinct, besides the upper and posterior edges which are covered by a heavy dermal fold. The dorsal surface is smooth and the venter is faintly granulate (Savage 2002). The eyes are large and the lower eyelid is reticulate. Females have a blunt snout in lateral profile (Duellman 2001). Males have a softly sloping snout from the eyes to the nostrils in lateral profile. The head is slightly convex and is narrower than the body.

Males have a maximum snout-vent length of 73.9 mm, and females 84.2 mm. If your frog has edema caused by kidney failure, humane euthanasia performed by your vet is an option.Agalychnis annae is a moderately large and slender frog.

Dying from kidney failure can be a slow, painful process.

To prevent edema, clean your frog's cage weekly and change its water frequently.

Since bacterial edema can be cleared up relatively easily at home and the one caused by kidney failure is always fatal, it is up to you whether to take your frog in to be seen by a vet.

Unfortunately, if your frog has edema caused by kidney failure, it will most likely die from the condition. If it is the bacterial kind, you should soak your frog in clean spring water for a few hours to clear out the infection. One is a bacterial infection and the other is from kidney failure due to vitamin toxicity. If your frog has swollen up, it is most likely caused by edema.
