Repeating argonaut design on a Minoan ceramic. The argonaut was the inspiration for a number of classical and modern art and decorative forms including use on pottery and architectural elements. Some early examples are found in Bronze Age Minoan art from Crete. [21] A variation known as the double argonaut design was also found in Minoan ...
Argonauta argo, also known as the greater argonaut, is a species of pelagic octopus belonging to the genus Argonauta. The Chinese name for this species translates as "white sea-horse's nest". [2] A. argo was the first argonaut species to be described and is consequently the type species of the genus.
The Argonautidae are a family of pelagic cephalopods that inhabit tropical and temperate oceans of the world. The family encompasses the modern paper nautiluses of the genus Argonauta along with several extinct genera of shelled octopods.
The argonaut was observed using the jellyfish as cover, rotating the animal to hide itself from potential predators (in this case the photographer). The argonaut was also seen using the jellyfish as a 'hunting platform', as it "manoeuvered its host close to a smaller comb jelly , quickly grasped it with another pair of tentacles and devoured it".
Depending on the species, the male may use it merely as a conduit to the female, analogously to a penis in other animals, or he may wrench it off and present it to the female. The hectocotyl arm was first described in Aristotle's biological works. Although Aristotle knew of its use in mating, he was doubtful that a tentacle could deliver sperm.
Argonauta nodosus [previously known as Argonauta nodosa [3] [4] [5]], also known as the knobby or knobbed argonaut, is a species of pelagic octopus. The female of the species, like all argonauts , creates a paper-thin eggcase that coils around the octopus much like the way a nautilus lives in its shell (hence the name paper nautilus ).
It was written around 350 BC. The whole work is roughly a study in animal anatomy and physiology; it aims to provide a scientific understanding of the parts (organs, tissues, fluids, etc.) of animals and asks whether these parts were designed or arose by chance.
Tortoise with cuttlebone Fossil cuttlebone of the Pliocene species Sepia rugulosa Fossilised cuttlebone-like gladius of Trachyteuthis [1]. Cuttlebone, also known as cuttlefish bone, is a hard, brittle internal structure (an internal shell) found in all members of the family Sepiidae, commonly known as cuttlefish, within the cephalopods.
