This cute little froggy is, unfortunately, critically endangered. Ballpoint pen, watercolour and soft pastel on paper.

1. Animal: Lemur leaf frog (Agalychnis lemur):
- These frogs have the remarkable ability to change colour depending on whether they are active or resting; greenish-yellow to blend in during the day, turning to a reddish-brown at night when they are most active.

- Lemur leaf frogs are found in Costa Rica, Panama, and some areas of Colombia. They live in forests on sloping mountainsides and in the humid uplands and lowlands.

- Females lay 15 to 30 eggs on the underside of a leaf and rain washes larvae into the water. Once in the water, tadpoles develop into adult frogs over 90 to 150 days. Lemur leaf frog lifespan is estimated to be between five and 10 years.

- Lemur leaf frogs are carnivores and eat insects, snails and other small invertebrates.

It is a very small frog: while females reach a length of 4.5 centimetres, males don’t even grow to 4 centimetres.

2. Why they are endangered?
The population of the lemur leaf frog fell by about 80% over a ten-year period. The massive declines are probably due to a fungal disease of chytridiomycosis. General habitat loss also remains a threat, and this is especially the case in Costa Rica where deforestation by squatters threatens Fila Asunción, one of the three known remaining population.
