Ezinamazenge

Ezinamazenge ziyihlelo elikhulu kunazo zonke lezilwane ezihuquzelayo; iningi lamalungu alo livame ukwaziwa ngokuthi izibankwa, kanti leli qembu lihlanganisa nezinyoka . Njengoba linemiqhinqa engaphezu kwezi-11,991, futhi iyindawo yesibili ngobukhulu yezilwane ezinomgogodla ezikhona (eziphilayo), ngemuva kwenhlanzi i-perciform .Ezinamazenge zihlukaniswa ngezikhumba zawo, ezinamazenga asamathambo noma ayizihlangu, futhi ngezikhathi ezithile ziyancibilika. Futhi zinogebhezi olunxane onyakazayo okwenza kube nokwenzeka ukunyakaza komhlathi ongaphezulu uma kuqhathaniswa ne- neurocranium . Lokhu kubonakala kakhulu ezinyokeni, ezikwazi ukuvula imilomo yazo kabanzi ukuze zikwazi ukwamukela izisulu ezinkulu uma kuqhathaniswa. Ezinamazenge yizilwane ezihuquzelayo eziphilayo ezinobungako obuhlukahlukene kakhulu, kusukela ku 16 millimetres (0.63 in) isigcikilishana ( Sphaerodactylus ariasae ) kuya ku- 6.5 metres (21 ft) inhlwathi egobile ( i-Malayopython reticulatus ).
