1. Le germon (Thynnus alalonga. Nob.) = Albacore (Thunnus alalunga)

Thunnus alalunga, commonly known as albacore or longfin tuna, is a species of tuna that belongs to the family Scombridae It is found in temperate and tropical waters across the globe in the epipelagic and mesopelagic zones. The albacore has an elongate, fusiform body with a conical snout, large eyes, and remarkably long pectoral fins. Its body is a deep blue dorsally and shades of silvery white ventrally. Albacore are pelagic predators that eat a wide variety of foods, including but not limited to fish, crustaceans, and cephalopods. They are unique among tuna in that their primary food source is cephalopods, with fish making up a much smaller portion of their diet. Albacore form schools based on their stage in the life cycle, but also combine with other tuna like the skipjack tuna, yellowfin tuna, and bluefin tuna. Once grown, schools are highly migratory.

2. La bonite à ventre rayé (Thynnus pelamys. Nob.) = Skipjack Tuna (Katsuwonus pelamis)

The skipjack tuna (Katsuwonus pelamis) is a medium-sized fish in the tuna family, Scombridae. It is a cosmopolitan pelagic fish found in tropical and warm-temperate waters. The skipjack tuna is a streamlined, fast-swimming pelagic fish, common in tropical waters throughout the world, where it inhabits surface waters in large shoals (up to 50,000 fish), feeding on fish, crustaceans, cephalopods, and mollusks. It is an important prey species for sharks and large pelagic fishes and is often used as live bait when fishing for marlin. The skipjack tuna has no scales, except on the lateral line and the corselet (a band of large, thick scales forming a circle around the body behind the head). It commonly reaches fork lengths up to 80 cm and a mass of 8–10 kg.
