UKO ZIBAYEHO

Inyamanswa zifite uruhu rukanze, ziba mu buryo bwihariye kandi zifite imyitwarire ikurikira:

1. Uruhu rukanze: Uruhu rwazo rugizwe n’ibintu biremereye bita scales (inkovu cyangwa amababa), bigira akamaro ko kubafasha kwirinda kugumana amazi menshi, kuko aya mazimwe atinjira mu mubiri wazo. Ibi bituma babasha kubaho mu bice by'ubushyuhe bwinshi cyangwa mu butaka burimo umwanda. Urugero ni nk'inzoka n'ibisamagwe.
2. Ubuzima bwo mu bushyuhe: ibikururanda ni inyamaswa zitagira ubushyuhe bwo mu mubiri bwihariye nk'inyamaswa zifite amaraso ashyushye. Ibi bivuze ko ubushyuhe bw'umubiri wazo buba bushingiye ku bushyuhe bw’aho ziri. Kubw’ibyo, zikeneye gusohoka mu zuba cyangwa gukingirwa n'ahantu h’umukonjo kugira ngo zibashe kugenzura ubushyuhe bw'umubiri wazo.
3. Ubuzima bwo kwirwanaho: ibikururanda biba bifite uburyo bwo kwirwanaho. Inzoka, nk'urugero, zifite uburyo bwo gukoresha ururimi rwazo kugira ngo zibone aho ziri mu buryo bwihariye. Ibyonnyi cyangwa ibikoko bimwe nka crocodiles na byo bikoresha ingufu zabo zo kurwanya abanzi cyangwa kurinda ibikorwa byabo.
4. Kwibika ibiryo: ibikururanda ni inyamaswa zishobora gufata ibiryo byinshi mu gihe gito, kuko zibasha kubibika mu mubiri wazo. Zishobora kugumana ibiryo mu buryo bworoshye, nk'ibisamagwe bimwe bisigara byicaye ku butaka bigatunganya ubushyuhe bwayo kugira ngo bibashe kubaho igihe kirekire.
5. Uko bitera cyangwa bigakura: ibikururanda ntizitera nk'inyamaswa zimwe; zikora amagi. Amagi yazo akura hanze mu butaka cyangwa mu mazi, ariko rimwe na rimwe ibinyamaswa bitera biragira uruhu rwazo kugira ngo bibashe gukura neza. Urugero ni nk'ibyuma n’ibyonnyi.

Mu buryo bwa rusange, inyamanswa zifite uruhu rukanze zibasha kubaho mu buryo butandukanye n'izindi nyamaswa, zifashisha ubushyuhe bw'ahantu ziri, kandi zigira uburyo bwihariye bwo kwirwanaho no kwitunga.
