Dziko lapansi lam'madzi am'nyanja limakhala ndi mitundu yambiri yosiyanasiyana. Pali mitundu yambiri ya zomera ndi zinyama zapansi pamadzi, kuchokera kuzomera zosangalatsa komanso zachilendo kupita kwa mitundu yonse yoimira yakuya, yayikulu ndi yaying'ono, yopusa yopenga komanso yopatulika, yodya nyama komanso kudyetsa mbewu.
Munthu wakhala akudziwa bwino anthu ambiri okhala munyanja kwanthawi yayitali. Ena a iwo amamva kukhala osavuta komanso omasuka m'madzi okhala ndi zojambulazo. Koma palinso zosadziwika, osaphunzira mokwanira ndi umunthu, mbali zina zaufumu wamadzi, zomwe zili mozama, pomwe ndizovuta kuti anthu afikire.
Kuzama kwa nyanja kumabisa nsomba zosawerengeka kwambiri pansi pa nyanjayi - brownie shark... Iye ndi wa Scapanorhynchus shark ndipo ndiye yekha woimira mtunduwu, wosaphunzira pang'ono ndi anthu chifukwa adadziwika posachedwa.

Mawonekedwe ndi malo okhala
Nsomba yowopsa iyi idadziwika ndi mayina ake. Mbali yake yakutsogolo, mawonekedwe otambasula akulu ndi owoneka bwino, omwe mawonekedwe ake onse amafanana ndi mlomo waukulu kapena hump. Munthuyu ndiwonso woyamba chifukwa ali ndi khungu losazolowereka - pinki.
Mtunduwu umapezeka mu nsomba chifukwa cha khungu lake lonse. Kuphatikiza apo, imakhalabe ndi kulocha kwa ngale. Izi sizikutanthauza kuti khungu la nsombayo ndilowonda kwambiri, koma zotengera zonse za nsombazi zimawonekera. Chifukwa chake ndi pinki yachilendo.
Mu 1898 idadziwika koyamba za brownie shark. Anawoneka koyamba mu Nyanja Yofiira pagombe la Yordano. Kuyambira nthawi imeneyo mpaka pano, ndi nsomba 54 zokha zamtunduwu zomwe zimadziwika ndi anthu.

Khalidwe ndi moyo
Shark goblin ali ndi chiwindi chachikulu kwambiri, chomwe chimapanga pafupifupi 25% ya kulemera kwake konse. Chiwindi chachikulu chotere chimathandiza nsomba kusambira pansi pamadzi, ndiye mtundu wake wa chikhodzodzo. Ntchito ina yothandiza pachiwindi ndikuti imasunga zakudya zonse za nsombazi. Chifukwa cha chiwindi ichi, nsomba iyi imatha kukhala yopanda chakudya kwa nthawi yayitali, mpaka milungu ingapo. Pa nthawi imodzimodziyo, kuyimba kwake kumakhala koipa pang'ono.
Maso a nsombayo siabwino kwenikweni chifukwa amakhala mokhazikika m'malo akuda amadziwe. Koma ili ndi makina otetezera bwino omwe shaki imagwiritsa ntchito posaka chakudya.
Ma receptors awa ali pamlomo wake waukulu ndipo amatha kununkhiza wovutikayo mumdima wathunthu wamnyanja kwamamita makumi angapo. Shaki ili ndi nsagwada yapadera komanso mano olimba kwambiri. Amangokhoza kuluma ndi zipolopolo zolimba komanso mafupa akulu.
Nsombazi nthawi zambiri sizimagwira nyama yake. Imakoka madzi pamalo pomwe wolandirira a shark adawonetsa kukhalapo kwa wovulalayo. Chifukwa chake, chakudyacho chimapita mwachindunji mkamwa mwa nsombayo. Nsagwada zake zazikulu zimatha kupindika ndikufalikira panja. Ndizovuta kupeza kutsutsana ndi mphamvu zoterezi, chifukwa chake, ngati nsombazi zimanunkhiza nyama, imadya nayo.
Nsomba iyi ndi mawonekedwe ake onse imabweretsa mantha ndi mantha, koma kwa anthu siyimakhala pachiwopsezo china, popeza sapezeka konse. Sikuti aliyense amatha kuthana ndi mtunda wopitilira 200 mita mozama.
