Definition
The term 'genus Cepphus' refers to a specific grouping of seabirds within the auk family, mainly the guillemots. In biological terms, a genus groups together closely related species that share similar characteristics. Think of 'genus' as the heading in a well-organized animal encyclopedia. 'Genus Cepphus' members are skilled divers, typically found in colder, coastal regions. This classification helps scientists understand evolutionary relationships and the diversity of bird life.
