The Cleaner Fish
Let's first start with the cleaner fish. This fish will swim into a shark's mouth and eat remnant food particles from the shark's teeth. The cleaner fish departs with a satisfied appetite, and the shark is happy because his teeth are cleaned in the process. The shark does not allow any other kinds of fish into its mouth without chomping down for a good lunch. Indeed, what other fish would dare attempt to swim into a shark's mouth! This type of relationship is called a symbiotic relationship. Creationists point out that these relationships clearly represent a design that could not have occurred by chance. Evolutionists have a very difficult time explaining how these types of relationships could evolve with time.
Nevertheless, an evolutionist will somehow have us believe that the cleaner fish eventually figured out he could go in the shark's mouth, and the shark eventually figured out that he should let him so as to maintain proper dental hygiene. The following illustrations portray the likely repercussions of this ill-advised bravery.
