Ikhono layo lokudla ukudla okunzima, okunamagobolondo aqinile linganikeza ukuqonda ekuthuthukiseni ubuchwepheshe bokucubungula ukudla obusebenza kahle. Ngaphezu kwalokho, imisipha yomhlathi yesilwane esinamazinyo ayikhulu namandla okuluma kungakhuthaza ukwakhiwa kwezinto eziqinile nezihlala isikhathi eside.

Ucwaningo Lwekusasa Ngesilwane Esinamazinyo Ayikhulu

Naphezu kokuba isihloko esithandwayo sengxoxo, inhlanzi ye-pacu isalokhu iwuhlobo olungafundiswanga kahle. Ucwaningo lwesikhathi esizayo lungagxila ekuziphatheni kwesilwane esinamazinyo ayikhulu, imvelo, kanye nokwakheka kofuzo. Ukwengeza, kunesidingo socwaningo olwengeziwe ngomthelela wemisebenzi yabantu emphakathini wezinhlanzi ze-pacu nendawo yokuhlala.

Ukuvala Imicabango Ngesilwane Esinamazinyo Ayikhulu

I-pacu fish, eyaziwa nangokuthi isilwane esinamazinyo ayikhulu, iwuhlobo oluthakazelisayo olunamazinyo ayi-100 ahlukile. Ukudla kwayo kwe-omnivorous kanye nekhono lokudla inyamazane enamagobolondo aqinile kuyenza ibe isihloko esibalulekile socwaningo kososayensi kanye nesihloko esithandwayo sengxoxo phakathi komphakathi jikelele. Nakuba isilwane esinamazinyo ayikhulu singabhekwa njengosongo kubantu, imizamo yokulondoloza imvelo iyadingeka ukuze kuvikelwe indawo yaso futhi kuqinisekiswe imikhuba yokudoba eqhubekayo.
