Many pelagic and demersal fish species, as well as marine mammals and diving birds, prey upon juvenile and adult longfin inshore squid. Marine mammal predators include longfin pilot whales and common dolphins. Fish predators include striped bass, bluefish, sea bass, mackerel, cod, haddock, pollock, silver hake, red hake, sea raven, spiny dogfish, angel shark, goosefish, dogfish, mako shark, blue marlin and flounder. These squid do have ways of evading predators too. They have a very complex way of swimming called jet propulsion. The fin stroke plus the propulsion creates a very unique way of swimming in the ocean. This can help squid get away from predators more efficiently.

The longfin inshore squid spawns year round and lives for less than one year. "Eggs are demersal. Enclosed in a gelatinous capsule containing up to 200 eggs. Each female lays 20 30 capsules. Fecundity ranges from 950–15,900 eggs per female. Laid in masses made up of hundreds of egg capsules from different females." They are also used for research on replicating their camouflage abilities due to the chromatophores in their skin, which reflect a different color depending on the angle at which the light is hitting them. A dead longfin can show a colourful display with its chromatophores by connecting its axons to a music player.
