The ornate horned frog is also known as a "Pacman frog" and referred to as a “mouth with legs” — and it is, appropriately, quite a glutton. It'll eat any prey that fits in its enormous mouth, from insects to lizards to mice to birds to other frogs. It'll even attempt to consume prey larger than itself.

The Lake Pátzcuaro salamander is only found in a single lake in Mexico, with an estimated population of less than 100 in the wild. For 150 years, nuns in a nearby convent have been raising a population in captivity — keeping the species alive, but also making them into "cough medicine".

The Galápagos pink land iguana is found only on the slopes of a single active volcano on one of the Galápagos Islands. Named for its pink scales, this land iguana was described as a distinct species in 2009 and is considered 'critically endangered' — with fewer than 200 left.

The armoured rat is covered in sharp spines that can grow as long as 3 cm (1.2 in) — a great defence against the snakes and ocelots that share its wet rainforest habitat. Additionally, if all else fails, this rat can drop its tail to confuse or distract a predator.

With a wingspan of almost 1 metre (3.3 ft), the spectral bat is the largest bat in the Americas and the largest carnivorous bat in the world. It's believed to find avian prey by smell and is attracted to distress calls from small bats caught in mist nets. It's also known as the "False Vampire", because it was previously thought to feed on blood.
