Editing Homarus (section)

==Description==
''Homarus'' is one of three extant genera of clawed lobsters to show dimorphism between claws – a specialisation into a crushing claw and a cutting claw. The other similar genera are ''[[Nephrops]]'', which is much more slender, and has grooves along the claws and the abdomen, and ''[[Homarinus]]'', the [[Cape lobster]] from South Africa, which is even smaller, and has hairy claws.<ref name="Nephropinae">[ftp://ftp.fao.org/docrep/fao/009/t0411e/t0411e09.pdf Subfamily Nephropinae Dana, 1852]{{dead link|date=May 2025|bot=medic}}{{cbignore|bot=medic}}, pp. 51–86 in [[#refHolthuis|Holthuis (1991)]].</ref>

While analyses of [[morphology (biology)|morphology]] suggest a close relationship between ''Homarinus'' and ''Homarus'', [[molecular phylogenetics|molecular analyses]] using [[mitochondrial DNA]] reveal that they are not [[sister taxa]].<ref name="Tshudy">{{cite book |author1=Dale Tshudy |author2=Rafael Robles |author3=Tin-Yam Chan |author4=Ka Chai Ho |author5=Ka Hou Chu |author6=Shane T.
