An unusually high abundance of long‐finned squid (Loligo pealeii) was observed around southern Newfoundland in August–September 2000.The prevalence of maturing females and mature males, along with the collection of a single viable egg mop, provide the first evidence of spawning of this species at the northern limit of its geographic range of distribution. A long-finned squid, which is about a foot long, has a giant axon that's about 100 times wider than the axon of a typical human nerve cell.

Longfin squid spawn year-round with peak production occurring in the summer and winter months. The circular muscle fibers of newly hatched paralarvae had different sizes, shapes, thick filament lengths, thin:thick filament ratio, myofilament organization and sarcoplasmic reticulum (SR) distribution than those of … According to a 2011 stock assessment, longfin squid are not overfished. Males grow more quickly and tend to be larger than females. There are two main squid fisheries in the US including along the Atlantic coast for long-finned squid and along the Pacific coast for market squid. West Coast "market squid" (L. opalescens) are 3 to 5 inches long; East Coast squid, including long-finned "winter squid" (L. pealei) and short-finned "summer squid" (Illex illecebrosus), are a bit larger. They have a short life span, reproducing right before they die at around six to eight months old. Widespread Mediterranean, Indo-Pacific Atlantic longfin squid, also called loligo squid or Boston squid. It is found in continental shelf and slope waters from Newfoundland to the Gulf of Venezuela, and occurs in commercial abundance from Southern Georges Bank to Cape Hatteras. They are usually pink or orange and mottled with brown or purple and can change their skin color and pattern at will to hide or escape from predators, help them hunt, and to communicate and attract mates.

Longfin squid and shortfin squid are highly resilient to fishing pressure. Longfin squid grow and mature fast. These recovery rates are lower in muddy and structurally diverse habitats where trawling may cause long-lasting, if not permanent damage. To address butterfish bycatch, fishery managers have implemented hard caps on the amount of butterfish that can be incidentally caught in the fishery. Long-finned squid are found in ma­rine habi­tats, usu­ally near sandy and muddy sea bot­toms, but also quite often in clean, coarse sand on the ocean bot­tom. “Shortfin squid are everywhere,” said Owen Nichols of the Center for Coastal Studies.
