Genus: a category used in taxonomy, which is below ‘family’ and above ‘species’. A genus tends to contain species that have characteristics in common. The genus forms the first part of a ‘binomial’ Latin species name; the second part is the specific name.
Gestation: the state of being pregnant; the period from conception to birth.
Invertebrates: animals with no backbone.
Melon: in cetaceans, the bulging forehead belonging to a number of species, which contains oil, muscles and nasal passages and is though to focus sound during echolocation.
