Pronunciation: [kˈɔːdɪdˌʌkt] (IPA) 
The word "caudiduct" refers to a duct or tube extending from the tail region of an organism. The correct spelling of this word is "caudal + duct," with the stress on the second syllable. In IPA transcription, the pronunciation is /ˈkɔːdɪdʌkt/. The first syllable "cau" is pronounced like "kaw," followed by the syllable "di" pronounced as "dih." The final syllable "duct" is pronounced just as it is spelled.
A caudiduct is a specialized anatomical structure found in certain animals, particularly in various species of fish. It refers to a tube-like passage or duct that connects the caudal fin (tail fin) with the body trunk or axial skeleton. The caudiduct serves as a conduit for various essential functions and processes within the organism.
In fish, the caudiduct enables the transmission of signals from the caudal fin, which is responsible for generating propulsion and steering, to the central nervous system and musculature of the body. This connection allows for coordinated movements, such as swimming and maneuvering in response to environmental stimuli. Additionally, the caudiduct facilitates the transport of nutrients, gases, and waste products between the tail and the rest of the body.
The structure of the caudiduct can vary depending on the species of fish. It may consist of a series of cartilaginous or bony segments, or it may be a flexible tube. Some species may have multiple caudiducts on either side of the fish's body, while others may have a single, central caudiduct. The size and complexity of the caudiduct can also differ between species, reflecting their unique adaptations and evolutionary history.
Overall, the caudiduct plays a vital role in the locomotion, sensory integration, and physiological processes of fish, contributing to their overall survival and functionality in their aquatic habitats.
To draw caudad, backward, or in the direction of the tail.
