Vampyromorpha
Quick Summary
The Vampyromorpha are a unique order of cephalopods, distinguished by their purplish-black, gelatinous bodies. These deep-sea dwellers are found worldwide and are characterized by having eight arms and two small, retractile filaments, which are not homologous to tentacles. A distinctive feature is the "deep web" connecting their arms. Currently, only one species belongs to this order.1
Cephalopods, as a class, are mollusks with a highly developed central nervous system forming a true brain. They possess a beak-like mouth and highly developed eyes. The class is divided into subclasses, including Nautiloidea (like the Nautilus), the extinct Ammonoidea (ammonites), and Coleoidea, which encompasses octopuses, squids, cuttlefishes, and belemnites.1
