Dekatenoi

Dekatenoi is a fictional genus of ten-armed cephalopods created for speculative biology and worldbuilding. The name combines the Greek prefix deka- meaning ten with the common taxonomic suffix -oi, chosen to evoke cephalopod nomenclature.

In the imagined taxonomy, Dekatenoi resides within Eukaryota, Animalia, Mollusca, Cephalopoda, Octopoda, and the fictional family Dekatenidae. The genus includes several described species such as Dekatenoi deca and Dekatenoi tentaculata. These species are described as having ten tentacles arranged in two equal groups around a central head and mantle.

Morphology and physiology: Dekatenoi species are described as having a relatively robust mantle, ten pliable tentacles with two distinct sizes, and a beak capable of processing crustacean prey. They are said to display rapid color and texture change due to well-developed chromatophores and papillae, enabling camouflage in varied habitats. They are believed to reach moderate sizes for cephalopods, with mantle lengths commonly reported between 0.5 and 2 meters in the speculative literature.

Habitat and ecology: In fiction, Dekatenoi are described as deep-sea or cold-water predators, inhabiting crevices and slopes where they ambush or probe with their tentacles. They may exhibit solitary or loosely social behaviors and engage in episodic cooperative hunting in some imagined ecosystems.

Notes: Dekatenoi is not a real genus; it appears in fictional and speculative contexts for worldbuilding and education. See also Cephalopoda, Octopoda, taxonomy.
