SINGAPORE - Five breathtaking species of the poison arrow frog have leapt their way into S.E.A. Aquarium at Resorts World Sentosa, including the dyeing, blue and Amazonian species.

These thumb-sized frogs are the first amphibians to be showcased in the aquarium, which boasts a collection of 100,000 animals, across 800 species.

Native to Central and Southern America, the frogs are part of the aquarium's ongoing plan to feature unique species and promote conservation awareness.

These conservation efforts are especially important as many of their species are now endangered as a result of deforestation to make space for farmland.

To accommodate more than 40 poison arrow frogs, S.E.A. Aquarium built a new exhibit to replicate the frogs' natural habitat in humid rainforests, with temperatures between 22 and 27 deg C.

Measuring 1.5 to 6 centimetres, poison arrow frogs pack a lethal punch in a tiny package. When provoked, they secrete deadly toxins to elude capture. Frogs with the brightest colours are usually the most poisonous. The most toxic species, the golden poison arrow frog, can be found in the aquarium.

Aquarists have taken pains to ensure that the new additions are not poisonous by carefully regulating their diet. Since ingesting poisonous insects induces harmful secretions, the frogs' diet consists of non-poisonous insects such as crickets and wingless flies.

Visitors to S.E.A. Aquarium can view these colourful frogs and other freshwater species at the Central and South American exhibits.
