"Scomber colias" refers to the Atlantic chub mackerel or Spanish mackerel, a species distinct from the common Atlantic mackerel (*Scomber scombrus*). It's found in warmer waters, often in the Mediterranean Sea and parts of the Atlantic. Think of it as the sun-loving cousin of the more common mackerel. It has a slightly different pattern and coloration compared to its relative. This species is also commercially important. 'Scomber colias' has a slightly bluer hue.
