-
Argonauta pacifica, commonly known as the Pacific argonaut or pacific paper nautilus, is a species of pelagic cephalopod belonging to the family Argonautidae. It is the only known species within the Argonautidae family found in the Pacific Ocean.
The Pacific argonaut possesses a unique and beautiful structure, with a shell resembling a delicate, thin, spiral coil. It is a relatively small cephalopod, measuring around 8 to 10 centimeters in length, excluding the tentacles. This species is sexually dimorphic, with females being significantly larger than males. The female possesses the distinctive shell, while males lack one entirely.
The shell of the Pacific argonaut is secreted by the animal's own mantle tissue and is not permanently attached to the body. This shell plays a critical role in protecting the female during reproductive periods. Female Pacific argonauts have two specialized tentacles that are used to create the egg case, which is attached to the internal surface of the shell. These tentacles are elongated and modified webbed arms.
The Pacific argonaut is a free-swimming species, found in warm waters of the Pacific Ocean, primarily in the tropical and subtropical regions. It can be found at various depths although it typically resides near the surface. Despite its delicate appearance, this species possesses the ability to adapt and survive in a range of environmental conditions.
Overall, the Pacific argonaut is an intriguing marine animal with its unique spiral shell, which has captivated the interest of scientists and marine enthusiasts alike.
Etymology of ARGONAUTA PACIFICA
The term "Argonauta pacifica" is a scientific binomial used to classify a species of pelagic octopus commonly known as the Pacific argonaut or the paper nautilus.
The word "Argonauta" has its origins in Greek mythology. In Greek mythology, the Argonauts were a group of heroes who accompanied Jason on his quest for the Golden Fleece in the ancient Greek epic poem "Argonautica" by Apollonius of Rhodes. The name "Argonauta" comes from the Greek words "Argo" (the name of the ship) and "nautēs" (meaning sailor or navigator). The choice of this name for the species is due to the resemblance of the female octopus' shell to a sailor's ship or craft.
The addition of the term "pacifica" indicates the specific habitat of this particular species, which is found in the Pacific Ocean.
