目前的知识生物学的鱿鱼家庭Gonatidae在亚北极太平洋是
综述迄今为止，Gonatus属有10种（其中两种尚未命名），
在亚北极太平洋已知有一种始针属的物种、六种拟Gonatopsis属的物种和两种Berryteuthis属的物种。其分布格局可分为三大类型：（1）跨太平洋种（2个亚型），（2）西北太平洋种，（3）东北太平洋种。Gonatidae科可分为两个广泛的生态类型：（1）肌肉型，表层至中层和广深型，（2）肌肉较少型，狭深型和Nektobenthic型。关于生殖腺的猎物知之甚少。然而，它们的捕食者多种多样，包括鱼类、海鸟和哺乳动物，因此生殖腺在亚北极太平洋的食物链中扮演着重要的角色。触手棒的结构，特别是变形为钩是追踪形态的重要特征
增长的变化。阐明了某些物种的异速生长。本文描述了两种商业性捕捞鱼种（北方拟性腺鱼（GonatopsisboreaUs）和长吻贝（Berryteuthis magister））的产卵生物学，但很少观察到非商业性鱼种的产卵成虫。性腺浮游幼鱼的季节性发生可能与春季浮游植物水华有关。
Current knowledge on biology of the squid family Gonatidae in the subarctic Pacific is
reviewed. Up to this date, 10 species of the genus Gonatus (of which two are unnamed yet),
a single species of the genus Eogonatus, six species of the genus Gonatopsis and two species of the genus Berryteuthis are known from the subarctic Pacific. Their distribution patterns can be classified into three major types: (1) trans-Pacific species (with two subtypes), (2) Northwest Pacific species, and (3) Northeast Pacific species. The family Gonatidae is divisible into two broad ecological types: (1) muscular, epi- to mesopelagic and eurybathic forms, and (2) lessmuscular, stenobathic and nektobenthic forms. Little is known about the prey of gonatids. However, their predators are diverse, including fishes, sea-birds and mammals, thus gonatids play an important role for the food-chain in the subarctic Pacific. Structures of the tentacular club, particularly metamorphose into hooks are important characters for tracing morphological
changes in growth. Allametrie growth of some species has been clarified. The spawning biology of two commercially fished species (Gonatopsis boreaUs and Berryteuthis magister) is described, but spawning adults of non-commercial species have seldom been observed. The seasonal occurrence of planktonic juveniles of gonatids may be related to spring phytoplankton blooms.
