How Do You Spell TROCHOSPHERE?

Pronunciation: [tɹˈə͡ʊkəsfˌi͡ə] (IPA)

Trochosphere is a term from the fields of zoology and marine biology that describes the larval stage of some invertebrate animals. The word is spelled using the International Phonetic Alphabet as /trəˈkɒsfɪər/, with the stress on the second syllable. The "ch" sound in the first syllable is not pronounced like a "k" but rather like a guttural "kh" sound. The final "e" is silent, and the word is typically pronounced truh-KOS-feer in English.

TROCHOSPHERE Meaning and Definition

1. Trochosphere is a term used in biology to describe a developmental stage found in certain types of organisms, particularly in some species of marine invertebrates. Specifically, it refers to a larval stage that is characteristic of mollusks, annelids, and some other phyla.

   The trochosphere is a roughly spherical and ciliated larva that exhibits several distinct anatomical features. It is characterized by the possession of a band of cilia, known as the prototroch, which encircles the body near its midpoint. These cilia enable the trochosphere to move and swim in a rotating or circular motion, hence the origin of its name, derived from the Greek word "trochos" which means wheel.

   Additionally, the trochosphere typically possesses a simple digestive system, with a mouth and anus located at opposite ends of the organism. It also contains other structures such as sensory organs, a pair of protonephridia for excretion, and a simple nervous system. The trochosphere stage generally lasts for a relatively short period of time before undergoing further developmental changes, leading to the formation of a new stage called the veliger.

   In summary, the trochosphere is an early developmental stage characterized by its distinctive shape, ciliated band, and basic anatomical structures. It serves as an important transitional stage in the life cycle of various marine invertebrates, aiding in dispersal and eventually giving rise to more complex forms of these organisms.
