Imvamisa, insikazi iyagwema abesilisa abagadayo. Uyehlisa ijubane bese untanta uye endaweni enesihlabathi esingajulile. Abesilisa bakhombisa ukuncintisana futhi bazungeze ushaka kuze kube yilapho owesilisa onamandla kunabo bonke eshayela ekhoneni elinesihlabathi. Owesifazane uphinde alume owesilisa ngaphambi kokulingiswa. Lokhu kuziphatha okuhlala izinsuku ezithile bese kuqala kaninginingi. Insikazi kancane kancane yehlisa ulaka lwayo futhi, ilungele ukuqhutshwa, ikhombisa ukuzithoba. Indoda ekhethiwe ibhukuda izungeze eyayo okokuqala emibuthanweni emikhulu, bese isondela ekugcineni kwayo kwe-caudal. Ukuxubana kwenzeka lapho owesilisa ebhukuda eceleni, ethinta ohlangothini lwesokunene lwabesifazane nangasemaphethelweni angemuva we-pectoral fins, futhi uhlala umzuzu owodwa kuya kwemibili kuphela. Ngemuva kokukhwelana, owesilisa akakhombisi intshisekelo ethile kowesifazane. Ekuthunjweni, abesilisa bavame ukuziphatha ngonya kwabanye abantu ngemuva kokulingiswa.
