Izinhlobo eziningi izinhlanzi babambeke njengoba ukudla cishe kuzo zonke izifunda emhlabeni wonke.Inhlanzi ibingumthombo obalulekile wamaprotheni nezinye izakhi zomuntu kubantu kuwo wonke umlando. IsiNgisi asinalo igama elikhethekile lokupheka lokudla okulungiselelwe kusuka kulezi zilwane, njengoba kwenzeka ngengulube ne- ngulube, futhi njengoba kunjalo ne-Spanish pescado vs. pez.Ezimweni zokupheka nezokudoba, inhlanzi ingafaka izimbaza, ezinjenge- molluscs, ama-crustaceans nama- echinoderms ; Ngokunabile, ukudla kwasolwandle kuhlanganisa zombili izinhlanzi nokunye ukuphila kwasolwandle okusetshenziswa njengokudla. Kusukela ngo-1961, ukwanda okumaphakathi konyaka kokusetshenziswa kokudla kwezinhlanzi okubonakalayo emhlabeni (amaphesenti angu-3.2) kudlule ukukhula kwabantu (amaphesenti ayi-1.6) futhi kweqa ukusetshenziswa kwenyama kuzo zonke izilwane zasemhlabeni, kuhlangene (amaphesenti angu-2.8) futhi ngawodwana (izinkomo, i-ovine, ingulube, nokunye ), ngaphandle kwenkukhu (amaphesenti angu-4.9).Ngokwemigomo ngayinye, ukusetshenziswa kwezinhlanzi kokudla kukhule kusuka ku-9.0 kg ngo-1961 kuya ku-20.2 kg ngo-2015, ngesilinganiso esilinganiselwa kumaphesenti ayi-1.5 ngonyaka.Ukunwetshwa kokusetshenziswa akwenziwanga ukukhiqizwa okwandisiwe kuphela, kodwa futhi yinhlanganisela yezinye izinto eziningi, kufaka phakathi ukumoshwa okuncishisiwe, ukusetshenziswa kangcono, izindlela ezithuthukisiwe zokusabalalisa kanye nesidingo esikhulayo, esixhumene nokukhula kwabantu, imali engenayo ekhulayo kanye nokufudukela emadolobheni.
