Článek představuje gigantické hlavonožce od současných krakatic a kalmarů po fosilní amonity a nautiloidy. Zpochybňuje nadsazené údaje o jejich velikosti a vysvětluje příčiny gigantismu, zejména změny prostředí a koevoluci s obratlovci. Novinkou je objev křídového Nanaimoteuthis, který mohl měřit až 19 m a patřit k největším predátorům své doby.

This article presents giant cephalopods, from modern giant-sized and other squids to fossil ammonites and nautiloids. It challenges exaggerated estimates of their size and explains the causes of gigantism, particularly environmental changes and coevolution with vertebrates. A recent discovery is the Cretaceous Nanaimoteuthis, which may have reached up to 19 m in length and ranked among the largest predators of its time.
