I-Internal Anatomy yeNdlovu yase-Afrika

I-Internal Anatomy yeNdlovu yase-Afrika.

Iindlovu zase-Afrika zizilwanyana ezisemngciphekweni wokuphela, ezifumaneka ikakhulu kwimimandla ye-savannah kwindawo yogcino eMpuma nakuMbindi Afrika. Ngaphambi kokuba sibe sengozini, esi silwanyana sasifumaneka kuyo yonke iAfrika, indawo yaso yendalo. Isilwanyana sifikelela kwi-4 m ubude kwaye sinobunzima obufikelela kwi-6.000 kg. Iindlovu eziziinkunzi zinkulu kwaye zinzima kunemazi.

Nangona ingqondo yendlovu yase-Afrika ithatha indawo encinci yokakayi bayo obukhulu, inobunzima bayo nasiphi na isilwanyana esanyisayo. Ubuchopho bendlovu endala yase-Afrika bunobunzima obufikelela kwi-5,5 kg, nangona imazi inqabile ukuba ibe ngaphezu kwe-4 kg. Ekuzalweni, ingqondo imalunga nesithathu sobukhulu bayo bokugqibela. Iindlovu zizilwanyana ezikrelekrele kwaye amandla azo okufunda ubuchule obutsha ayanda njengoko ubuchopho bazo bukhula ngobungakanani.

Inkqubo yokwetyisa

Umthamo wokutya otyiwa yindlovu yase-Afrika ngosuku uhambelana malunga ne-5% yobunzima bayo. Ezi zilwanyana zinokutya ukuya kutsho kwiiyure ezili-16 ngosuku olunye. Ubude bubonke bamathumbu ayo bumalunga nama-35 m. Iindlovu zitya iintlobo ngeentlobo zezityalo, kodwa inkqubo yazo yokwetyisa igaya ngempumelelo i-44% yokutya. Le nkqubo yokwetyisa ingasebenzi kakuhle ibangela ukuba esi silwanyana sikhulu sivelise malunga ne-160 kg yelindle ngosuku.

Inkqubo yokujikeleza

Intliziyo yenkunzi yendlovu yase-Afrika inobunzima obuya kuthi ga kwi-27,5 kg kwaye ine-vertex ephindwe kabini. Oku kuthetha ukuba kukho amanqaku amabini ezantsi kwelungu, kunokuba abe mnye, njengoko kubonakala entliziyweni yomntu. Ukongezelela, xa imile, le ntliziyo inkulu ijikelezisa igazi kumzimba wendlovu obetha phakathi kwama-25 nama-30 ngomzuzu. Ngaphakathi kwinethiwekhi yemithambo yegazi, isitya esinye sinokulinganisa ngaphezu kwe-3 m ubude. Oku kuthetha ukuba iindlovu kufuneka zigcine izinga loxinzelelo lwegazi rhoqo ukuze zingawi. Ezi zilwanyana zineenqanawa ezininzi ezindlebeni zazo ezinkulu, kwaye zinokupholisa igazi elijikeleza umzimba wazo ngokuzishukumisa.

Inkqubo yokuphefumla

Iindlovu zaseAfrika zilawula ukunyuka kwamaxabiso emiphungeni ngokusebenzisa izihlunu. Kwithuba lomzuzu omnye, indlovu enjalo iya kuba phakathi kwemijikelo emine ukuya kwelishumi yokuphefumula, kuxhomekeke kwinqanaba lomsebenzi. Okukhona uphezulu inqanaba lomsebenzi, kokukhona liphezulu inani lokuphefumla ngomzuzu wendlovu yaseAfrika. Umoya omninzi uphefumlelwa ngesiqu, uze uphefumle omnye ngomlomo.
