Most organs in the animal world, not just limbs, have several uses, illustrating an economy that reflects designed parsimony. Animals are wont to imitate other animals, or even leaves, rocks or other aspects of their surroundings. One fish, which looks very much like a dead leaf, and is appropriately called the Leaf fish, is tan or brown colored with appropriate leaf resembling mottling.
It sports a stout barbell on its chin that looks like a leaf stem, and the pectoral fins are so transparent that they are practically invisible, making this water wonder appear even more like a leaf. Leaf fish seem like idle fishermen—they lie motionless on their side, almost invisible, until a fish strays into their view. Then, in a split second with a sudden dart, they engulf their prey (Grant, 1969).
Most every child has watched the many kinds of colorful fish glide effortlessly through their watery world. Even the water giants, whales and porpoises enter our lives through TV or the many aquatic wonder presentations in animal parks such as SeaWorld. When a child beholds one of the various types of colorful rainbow fish, the bright vivid reds, blues, purples and yellows often bring amazement.
One fish, the Cuttlefish, shoots out a black ink-like fluid called sepia to protect themselves, darkening the water and enabling them to easily escape their enemies. They have not two, but ten arms, including two long “catch hooks” that can rapidly extend outward and grab a fish that may innocently swim too close to them. On their “hands” are hundreds of tiny suction cups that enable them to get a firm hold on their prey (Grant, 1969). Neither fossils nor living animals have been found to be a plausible evolution scenario for their origins. The cuttlefish screams design and negates evolution.
