The art of camouflage
Daintree Rainforest showcases the art of camouflage and is renowned as the World’s longest surviving rainforest. This claim is based on the number of families of primitive flowering plants called Angiosperms that remain today. However, the enormity of this claim is dwarfed by the intricacy and variety of inter-relationships that contribute to an eco-system that embraces rainforest and reef in a continuum of biological diversity beyond understanding.
As resident custodians, our presentation of this irreplaceable global treasure aims to expose facets of the rainforest that provide a complex picture; one that will be valued by the people who are concerned for its conservation and protection.
The refinement of strategies for survival, such as camouflage and mimicry, are indicated early in our tour. I pause before a shrub with a bird dropping clearly showing against a vibrant green leaf. I ask my guests to look closely. They lean forward, peering with distaste at the white splodge with black markings. That’s a spider, I tell them, a bird-dropping crab-spider. Distaste changes to excitement and admiration as they see the cleverness. I show them a web on another leaf, made by the same spider that closely resembles the white splatter of liquid in bird faeces. There is even a runnel in a dip in the leaf, simulating flowing movement. The spider sits on its purpose-built web looking exactly like a bird-dropping. This is its protection. What bird wants to eat its own excrement? Not only does the spider look like a bird-dropping, it gives out a smell that attracts insects that like to eat bird-droppings. These insects, small beetles and flies, are swiftly grabbed by the spider, bound in webbing and left on the edge of a leaf for more leisurely ingestion.
