Photo Kubonisa yayo.

Lamprey River wohlulwe le bushing (awayengabemi kwimimandla yonxweme lolwandle desalinated kwaye zizala asemilanjeni) kunye umnyango omnye (abahlala emilanjeni).

Lamprey River - uhlobo abaxhaphaza ekutyeni nasemakhalaneni. Feeds yi ofunxayo kwi abahlali zolwelo badla iintlanzi ngokuthi nibaphanga yenyama negazi. Yena olidla-kudla, lwalunye ukhamba ofunxayo elinokuthatha imihla emininzi, uyakwazi ndaxhwitha nexhoba eyona kakhulu ubunzima babo. iintlanzi ezininzi emva ezinjalo "incoko yababini" babulawa amanxeba akhe, njengoko igazi labo ufumana into enqanda amahlwili.

Kunyaka ngaphambi besasaza lamprey umlambo uyayeka ukutya. Emzimbeni wayo kukho utshintsho ezibalulekileyo: isidima emathunjini, nobubovu amathe kufa, amaphiko amanakani ziye zadityaniswa elinye, imazi kubonakala eyinqaba ezimpundu kunye namaqanda kwasekwa, kwaye inkunzi - papilla angasese kunye nobisi.

Ekhuthazwa umlambo lamprey kumacandelo omlambo kunye ngezantsi elikhawulezayo ngoku pebbly, kubunzulu. Ngexesha zidala, inkunzi kwakha indlwane ngokumba imingxuma emazantsi. Female lonke ixesha ezidada phezu kwakhe, ochukumisa esiswini kwentloko yakhe, ngokungathi elohlokondiba. Ekugqibeleni kubhaliwe nzulu kancinci kuphela umngxuma. Xa kugqityiwe, imazi anamathela ukuya iliwa kufuphi yentaka, kwaye inkunzi unamathela kuyo, ngokuthe ngcembe kancinane indebe ofunxayo kwi ecaleni intloko nomsila usonga engeenxa zonke kuyo. Products kwamadlala ukuvelisa uphoswe ngaxeshanye. Emva zidala, isibini into efihlakeleyo phakathi kwamatye kunye kungekudala afe.

Amaqanda, nto leyo ngaphezu kwama-20 amawaka, 2 iiveki kwindawo kubonakala ngokuba peskoroykami. Zibonakala njengezinambuzane ezincinane umbala elityheli.
