An yi imanin cewa kunkuru yana da girma saboda yana zaune a ƙarƙashin ruwa ko kusa da ruwa. Bisa ga haka, an ba ta da siffofi na dabbobi masu ban mamaki waɗanda suke da numfashi na fata, tsummoki da huhu kuma ba za su iya rayuwa ba tare da ruwa ba (suna kiwo a cikinsa).

Amma kunkuru sun ci gaba kadan a cikin juyin halittarsu kuma ba kowa bane ke bukatar ruwa. Nau'in hamada suna yin ba tare da shi ba kuma suna sanya ƙwai a cikin yashi. Kuma ruwa ya tashi a cikin ƙasa don samun zuriya. Sabbin kunkuru masu kyankyashe suna neman asalinsu.
