Normally, it travels in fairly large schools and is common offshore in the vicinity of New York City, where it is known as "skipjack" because of its habit of jumping from the water. (However, the name "skipjack" more commonly refers to the skipjack tuna, Katsuwonus pelamis.) The spawning season is June, and specimens 12–15 centimetres (4.7–5.9 in) long are taken in September off Long Island.
