Relatively small in size, the little tunny may grow to be a meter in length, although they are often much smaller. This species can weigh up to 12 kg, but, as stated with their length, tend to be much smaller (Robins, 1986).

A study aimed at gaining a better understanding of the diet of little tunny within a population in the Mediterranean Sea examined the stomach contents of 187 little tunny. The study found that the little tunny has a broad diet, including teleost fish, cephalopods, crustaceans, and vegetation. Of said prey items, teleosts accounted for the most amount of weight and were found in over 90% of the stomachs of all the observed specimens. A table displaying the appearance of multiple food items in the stomachs of the observed specimens gives a breakdown of the diet of the little tunny and shows the preference of teleost fish above other food items (Falautano, M., et.al.,
