Classification of Marine Organisms

Classification is a way of categorizing organisms that enables an easy process of identification of such organisms. All living things are classified by grouping them under specific categories. The grouping is done based on the close relativeness of the organisms. The classification tool requires knowledge of characteristics, differences, and similarities between different organisms.

In 1798, a stuffed platypus specimen was delivered to the British Museum. Reports that it laid eggs created much confusion. To modem biologists, a platypus is clearly a mammal. It has fur and the females produce milk. Young animals have typical mammalian teeth that are replaced by hardened pads of the bill as the animal matures. Why do you think modem biologists can more easily accept that a mammal can have some reptilelike traits than scientists who were considering this animal in the late 1700s?
Deathly Lamprey Repellent Predation by sea lampreys on native fishes in the Great Lakes is an ongoing problem. To help solve it, Michael Wagner and his team test methods of repelling lampreys. They carried out an experiment to investigate reports that sea lampreys detect the scent of lamprey carcasses and tend to avoid them. The researchers made alcohol-based lamprey carcass extracts, then observed what happened when lampreys were put in tanks and exposed to either this extract or to alcohol alone. FIGURE 25.6 shows their results. FIGURE 25.6 Effectiveness of carcass extracts as a lamprey repellent. Mean proportion of lampreys on the scented side of the test tank during B trials with 10 lampreys. Lampreys were placed in the tank for 20 minutes before exposure to alcohol or carcass extract and remained there for 40 minutes after exposure. The upper graph shows results with alcohol as the stimulus; the lower shows the results with carcass extracts. Bars indicate standard error. Why was it necessary to test the response of lampreys to the scent of alcohol alone?
