Katsuwonus pelamis, commonly known as skipjack tuna, is a species of fish belonging to the family Scombridae. It is a small to medium-sized pelagic fish found in warm waters of the Atlantic, Indian, and Pacific Oceans. Skipjack tuna has a cylindrical-shaped body with a streamlined and elongated appearance, typically measuring between 50 to 80 centimeters in length and weighing around 10 kilograms.
The dorsal side of Katsuwonus pelamis is dark blue to metallic black, while the ventral side is silvery white. They possess distinct longitudinal stripes along their body, diamond-shaped patches on their belly, and a series of small finlets located behind the second dorsal and anal fins. Skipjack tuna are known for their exceptional swimming speeds and agility, making them one of the fastest fish species in the ocean.
Katsuwonus pelamis primarily feeds on small fish, squid, and crustaceans. They are highly migratory and tend to form large schools that can vary in size from a few fish to thousands. These schools are often found near the surface of the ocean, following temperature gradients and currents.
Skipjack tuna is a valuable commercial species and is extensively fished worldwide. Its flesh is sought after for its firm texture and mild flavor, making it a popular choice for sashimi, canned tuna, and various other seafood dishes. Additionally, Katsuwonus pelamis plays a crucial ecological role in marine ecosystems as both predator and prey, contributing to the overall balance of the oceanic food webs.

The etymology of the term Katsuwonus pelamis can be broken down as follows:
1. Katsuwonus: This is derived from the Japanese word katsuo, which means bonito or tuna. Katsuwonus is a combination of katsuo and the Greek word onos, which means donkey. This name was assigned to the fish due to its speed and donkey-like appearance when swimming.
2. Pelamis: This word originates from the Greek mythology and refers to a sea serpent. The snake-like appearance of the Skipjack tuna was the reason behind its designation as Pelamis.
