I-tuna ingafinyelela ubude bomzimba obufika kumamitha amabili nesigamu. Njengomthetho, i-tuna inesisindo esingaphezu kwamakhilogremu angu-20, amanye amakhilogremu angaphezu kuka-100. Kodwa lezi ziyizibonelo ezinkulu kakhulu. I-tuna inomzimba ompunga-osiliva noma oluhlaza okwesibhakabhaka. Izikali zabo zincane futhi zibonakala eduze kuphela. Uma usuka kude, kubukeka sengathi banesikhumba esibushelelezi. Isici esikhethekile se-tuna ama-spikes ayo emhlane nasesiswini. Amaphiko e-caudal e-tuna amise okwesikela.
