both vertebrateand invertebrate‚ but males do not bear a penis in every animal species‚ and in those species in which the male does bear a so-called penis‚ the penes in the various species are not necessarily homologous. For example‚ the penis of a mammal is at most analogous to the penis of a male insect or barnacle. The term penis applies to many reproductiveintromittent organs‚ but not to all; for example the intromittent organ of most cephalopodais the hectocotylus‚ a specialised arm‚ and male

Shaw’s naturalist’s Miscellany along with the koala‚ Kangaroo‚ wombat and emu. The most curious was the platypus. Since its first discovery there has been much debate as to whether it is a mammal and how it should be classified.

It has fur like other animals‚ but it has a beak like

three types of mammals based on how their young develop. The three types of mammals based on the how their young develop are: Monotremes‚ Marsupials‚ and Placental.

Topic: Platypus Communication Mammals have a variety of methods to communicate‚ but an often forgotten mammal‚ the platypus must also communicate. The topic I chose to research was platypus communication. Platypus must be able to communicate within their environment and with each other/predators. The most well-known form of communication is apparently vocalizations. Platypus can actually vocalize a growling noise‚ but there has not been enough conclusive studies done to come to a conclusion as
