aplacophora

A marine biologist carefully examines an aplacophora specimen in a laboratory.

Definition

Noun 1. A taxonomic order of deep-sea mollusks: Aplacophora is an order within the class Solenogastres (or sometimes grouped with Caudofoveata in the class Aplacophora), characterized by worm-like, shell-less bodies covered in a cuticle with embedded calcareous spicules. They are considered primitive, deep-sea mollusks.

Usage
  • The class Aplacophora includes small, benthic marine invertebrates.
  • Scientists study the anatomy of Aplacophora to understand early molluscan evolution.
  • Due to their deep-sea habitat, members of the Aplacophora are rarely observed.
Advanced Usage
  • In taxonomic discussions, Aplacophora is sometimes used to refer to a class comprising the orders Solenogastres and Caudofoveata, rather than a single order.
  • The term is primarily used in scientific literature (zoology, marine biology, taxonomy).
Variants and Related Words
  • Aplacophoran (noun/adjective): A member of the Aplacophora; relating to the Aplacophora.
    • The aplacophoran specimen was collected from a hydrothermal vent.
  • Solenogaster: A common name for an organism in the order Solenogastres, often synonymous with Aplacophora in broader usage.
Synonyms
  • Solenogastres (as an order name)
  • Deep-sea mollusks (descriptive, not taxonomic)
Related Terms & Context
  • Mollusca: The phylum to which Aplacophora belongs.
  • Amphineura: An older, sometimes used taxonomic grouping that included Aplacophora and Polyplacophora (chitons).
  • Shell-less mollusk: A descriptive term highlighting a key characteristic.
  • Benthic: Referring to the ocean floor, which is their habitat.
