Chromatophores, specialized pigmentation cells, contract or expand to enable the stripes to transform from blue-tinged to lavender when the fish is excited.

[5] A study on its habitat preferences utilized opportunistic occurrence data to determine that the eastern Pacific Ocean is among the most ideal bodies of water for the species to inhabit.

[6] Additionally, it was discovered that its largest populations reside in water bodies with dissolved oxygen levels from 4.5 to 5.5 mL/L and a sea surface temperature between 20 and 28 degrees Celsius.

[7] An abundance of nutrients supports the growth of aquatic plants and algae, which contributes to the congregation of species that feed upon them, the striped marlin's principle prey.

[3][9][10] The striped marlin is a top predator, feeding mainly on a wide range of fish such as sardines, mackerel, small tuna, and cephalopods.

One study off the coast of Mexico found that it preferred schooling fish such as the chub mackerel, Etrumeus sadina and Sardinops caeruleus.

Also, it is a lean source of protein with minimal sodium and low levels of saturated fat, making it a practical choice for a nutritious meal.
