Smell Many animals are dependant on their sense of smell, especially at night. some animals such as ardvarks have nostrils at the tip of their beaks which they use to sniff out insects and worms under the ground. Snakes also "taste" the air to help them locate prey.
A tarsier showing very large eyes
Sight Many nocturnal animals rely upon their sense of sight in order to find their way around the jungle. Having large eyes that open up really wide to let light in are useful as it is quite dark on the forest floor and very dark in the shrub layer at night.
Sloths have very large claws
Claws In the rainforest claws are very useful for both predators and prey. Claws are mainly used to help grip tree trunks and branches whilst climbing but can also be used by predators to help kill their prey.
Toucans have brightly coloured beaks
Bright colours Many animals such as snakes and poison dart frogs use bright colours to warn other animals of their poisonous capacity. Most brightly coloured animals are actually poisonous but others use it as a disguise and look very similar to other poisonous animals but do not have venom. Other animals such as parrots are brightly coloured to attract mates.
Hearing Some animals that live in the rainforest have developed very large ears to help pinpoint sounds better. Some nocturnal animals such as Bats use echo detection to help "see" their way around the forest. This is especially useful when it is dark to ensure they dont fly into branches or creepers in the lower layers of the rainforest as some other animals might do.
Touch Many animals in the rainforest have a very developed sense of touch. they use whiskers, hairy snouts and very sensitive skin to determine what is around them. whiskers can tell an animal if a space is large enough for them to squeeze through. The whisker is attached to a nerve ending that sends a signal to the brain if a whisker is touched.
Wings Wings are very useful for animals living in the rainforest, bird in the rainforest. Wings mean that they can negotiate the maze that is the canopy with ease. Predatory birds can swoop and take their prey by suprise and whisk it away just as quickly. Prey birds would be very hard to catch by predators as they can fly away to where predators without wings couldn't rech.
A gecko is well camouflaged
Camouflage Prey and predators both use camouflage to help them blend into their suroundings. Predators use camouflage to help them sneak up on prey so that they have the element of suprise on their side. Prey animals use it to blend into the environment and to hep avoid being seen by predators. A few animals such as chamelions and geckos have the ability to change their colour according to the environment.
