siphonophore

Thân thiện

A siphonophore drifts gracefully in the deep blue ocean.

Definition

Noun: A siphonophore is a complex, free-swimming or floating marine animal that is actually a colonial organism. It is composed of many specialized individual zooids that are physiologically integrated and function together as a single unit. They are often transparent or brightly colored and are found in ocean waters.

Usage

The word "siphonophore" is used specifically in marine biology and zoology to describe this unique type of colonial animal. It is a countable noun.

Examples

• The siphonophore is one of the longest animals in the world, with some species reaching over 40 meters.
• Scientists used a remote-operated vehicle to observe a bioluminescent siphonophore in the deep sea.
• The Portuguese man o' war is a well-known type of siphonophore.

Advanced Usage

• The term is often used to highlight the colonial nature and specialized division of labor among zooids, distinguishing it from a single, unitary organism like a jellyfish.
• It can be used metaphorically to describe a complex system where many interdependent parts act as one.

Variants and Related Words

• Siphonophorae (noun): The scientific order name for these organisms.
• Zooid (noun): An individual animal that is part of a colonial organism like a siphonophore.
• Colonial organism (noun): A life form where many individuals live closely together, often with division of labor.

Synonyms

Notes on Meaning

While often confused with jellyfish, a siphonophore is not a single animal but a colony. The most famous example is the Portuguese man o' war (Physalia physalis), which has specialized zooids for flotation, feeding, reproduction, and defense.
