Izilwanyana ezinamanzi, okanye amazinyo angamazinyo?

Ininzi inokuqiniseka, kunokuba isilwanyana 'sinozinyo', siyingozi nakakhulu. Ushaka emlonyeni unamawaka amaninzi (ezintathu ukuya kwishumi elinesihlanu kuye kuxhomekeke kwiintlobo) ezinamazinyo ezibukhali azinzileyo. Yingakho i-shark kunye nabantu abaziphethe igazi bebhekwa njengentlanzi, kodwa akukho naluphi na le nkonkcoza engenakunobungozi, kuba kungekhona wonke umntu owaziyo amazinyo amaninzi enkonkqo, iifoto kunye nemifanekiso efumaneka kwiincwadi ezininzi zezingane.

Ayikho inkohlakalo eyoyikisayo yerhamncwa

Kuye kubonakala ukuba inkohlakalo inobunzima ngaphezu koshaki. Uninzi lwamazinyo enkonkqo yamagilebhisi. Umlomo wakhe sele unamazinyo amawaka amawaka angama-25, apho unokugaya ngokukhawuleza iziqu ezinzima kunye namaqabunga.

Kubalulekile ukuba uqaphele ukuba ezi azinjalo kanye ngamazinyo esiqhele ukuthetha. Kwintsimi yomlomo ye-cochlea kukho okubizwa ngokuba yi-radulas-i-apparatus ekhethekileyo, efana ne-grater. Apha, kunoko, kubalulekile ukuba ingakanani inkohlakalo enamazinyo, kodwa indlela asebenza ngayo. Ifumaneka kumphezulu we-odontophora (uhlobo olulwimi "ulwimi"), i-radula ayisebenzeli ukulila, kodwa ukukhangela nokutywala ukutya. Iqukethe iplastiki ye-basin (i-membrane ye-radular) kunye namazinyo anama-chitinous atholakala kwimida emininzi. Zonke ezi zixhobo zisebenza ngomgaqo wesidlo, esinamabhakethi amaninzi njengenqatha yamazinyo. Zizo zenzeke izinto ezinobunzima ezithintela izondlo ezithatha isondlo sokutya. Ezinye iintlobo ze-gastropod zisetyenziswe njenge-drill, ngoncedo apho inkohlakalo ivula igobolondo layo lixhoba.

Ezinye iinkalo ezithakazelisayo ukusuka ebomini beemiski

• Inkqubo yeentlanzi ye-cochlea iqulethe malunga nama-neurons amawaka angamashumi amabini. Ingqondo yomntu, xa kuthelekiswa, iqukethe iibhiliyoni eziliqela.
• Ama-receptors e-Olfactory atholakala kumntu ngaphakathi kwempumlo, kwiimiski zifumaneka kwiimpondo. Ngamanye amazwi, iimpondo zimpumlo ngaphakathi.
• Kukholelwa ukuba imisipha ayiboni ngokwenene ngokoqobo, kodwa ikwahlula kuphela ukukhanya nobumnyama.
• Zingaphi amazinyo inkokhane incike kwiintlobo ezahlukeneyo. Ngokuqhelekileyo inani labo lisuka kwi-15 ukuya kumawaka ama-25.
• Uninzi lweemigibe zi-hermaphrodites.
• Inkqonkqo enkulu Akhatin fulik ifinyelela ubude be-20 cm, kodwa ihamba ihamba kancane kunomnquba wamagilebhisi.
• Inyama yale mollusc iqukethe iiprotheyini ezininzi kuneeyayi yenkukhu. Ukongezelela, ityebile kwi-calcium, isinyithi kunye nama-acid acids. Ngenxa yoko, zisetyenziselwa ukutya.
• Kungakhathaliseki ukuba mangaphi amazinyo enenkukhu, unomlenze owodwa, ngoko ke uhamba ngokukhawuleza. Isantya esiphezulu sokuthi isilwanyana sikhula malunga ne-7 cm / min.
• Isona sikhulu kunazo zonke izigodo eziye zafumana zilingana neekhilogram ezilishumi elinesibhozo, kwaye indlu yayo yayingamamitha angamashumi asixhenxe ubude.
• Uninzi lweemangqele zineqabunga elinesigxina (kwinqanaba), ukuba libhekwa kwiphepha elijikelezayo. Ukuphikisana ngokukhawuleza kweeyure kuncinci kakhulu.
• Iingxowa zazisetyenziselwa njengamayeza kunyango lwezifo zesisu kunye nokuvuvukala kwento, kunye nokuyeka ukuphuma.

Ekupheleni kwenkcazo yenani lamazinyo enokhenkco, kufuneka kuqatshelwe ukuba akayena umgcini werekhodi "kwizinyo" kwimbuso yezilwanyana. Iqhawe elipheleleyo li-slug. Unamazinyo amawaka angamashumi amathathu.
