Puffin are closely related, together composing the subfamily Fraterculini. The scientific name "Fratercula" is derived from Latin and means "little brother", a reference to the black and white plumage, which resembles monastic robes. The English name "puffin" – puffed in the sense of swollen – was originally applied to the fatty, salted meat of young birds of the unrelated Manx shearwater ("Puffinus puffinus"), formerly known as the "Manks puffin". Puffin is an Anglo-Norman word (Middle English "pophyn" or "poffin") for the cured carcasses of nestling Manx shearwaters.

Summerland Peninsula Bird Area. It is home to one of the largest Little Penguin ("Eudyptula minor") breeding colonies in Australia, the second largest breeding colony of Australian Fur Seals ("Arctocephalus pusillus doriferus") in the world, one of the largest breeding colonies of Greater crested terns ("Sterna bergii") in Victoria and an important breeding ground for Short-tailed shearwaters ("Puffinus tenuirostris"). Several plants regarded as rare or threatened in either Victoria or Australia have been recorded on the peninsula, including River Swamp Wallaby-grass ("Amphibromus fluitans") listed as vulnerable in Australia. The peninsula was significantly modified by agricultural, residential and recreational developments until the 1980s
