Actinotrochae is a term that is commonly used in biology, particularly in the study of marine organisms. It is a unique term that has a specific meaning, and it is important to understand its definition, origin, and associations. In this article, we will explore the meaning and significance of actinotrochae.
Definitions
Actinotrochae is a larval form of marine invertebrates, which includes annelids, mollusks, and some echinoderms. It is a planktonic larva that has a distinctive shape, with a band of cilia around its body that is used for locomotion and feeding. The cilia are arranged in a spiral pattern, which gives the larva its unique appearance.
Origin
The term actinotrochae is derived from the Greek words “actino,” meaning ray or beam, and “trochae,” meaning wheel or disk. The name refers to the spiral band of cilia that surrounds the body of the larva, which resembles a spinning wheel or disk.
Meaning in different dictionaries
Actinotrochae is not a commonly used term, and it may not be found in all dictionaries. However, some biological dictionaries and encyclopedias provide a definition for the term. For example, the “Dictionary of Marine Natural Products” defines actinotrochae as “a planktonic larval form of some marine invertebrates, characterized by a spiral band of cilia around the body.”
Associations
Actinotrochae is associated with the early stages of development of many marine invertebrates. It is an important larval form that allows these organisms to disperse and colonize new areas. The cilia on the actinotrochae larva are used for both feeding and locomotion, allowing the larva to move through the water and capture small particles of food.
Synonyms
There are no commonly used synonyms for actinotrochae, as it is a specific term that refers to a unique larval form.
Antonyms
There are no commonly used antonyms for actinotrochae, as it is a specific term that refers to a unique larval form.
The same root words
The root words “actino” and “trochae” are used in other scientific terms. For example, “actinometer” is a device used to measure the intensity of radiation, and “trochophore” is another type of larval form found in marine invertebrates.
Example Sentences
- The actinotrochae larva of the marine annelid is easily identifiable by its spiral band of cilia.
- The planktonic actinotrochae larva of the mollusk is an important stage in its development.
- The cilia on the actinotrochae larva allow it to move through the water and capture small particles of food.
