The white-tipped sicklebill uses its extremely decurved bill to reach inside sharply curved flowers, allowing it to drink nectar other nectarivores cannot reach. It is also a ‘trapliner’ — repeating the same foraging circuits, visiting favourite flowers along its particular route.

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.
