How Do You Spell BIPINNARIA?

Pronunciation: [ba͡ɪpɪnˈe͡əɹi͡ə] (IPA)

The word "Bipinnaria" is a scientific term used to describe the larval stage of starfish and some other echinoderms. The spelling can be explained using IPA phonetic transcription as /baɪˌpɪnˈnɛərɪə/. The second syllable is pronounced as "pin" and the stress falls on the third syllable. The prefix "bi-" means "two," while "pinnaria" is taken from the Latin word "pinnatus," meaning "feathered." The bipinnaria larva has two rows of cilia, resembling feather-like structures.

BIPINNARIA Meaning and Definition

1. Bipinnaria is a term used in the field of biology, specifically in the study of marine invertebrates, to describe a larval stage of certain animals belonging to the phylum Echinodermata, particularly starfish (class Asteroidea). It is also referred to as a bipinnate larva.

   The bipinnaria is characterized by its unique physical appearance and features. It has a bilaterally symmetrical body shape, typically disc-like or oval, and is often transparent or slightly pigmented. The defining characteristic of the bipinnaria is the presence of two rows of cilia (fine hair-like projections) on each side of the body, which it uses for locomotion and feeding.

   During this larval stage, the bipinnaria actively swims in the water column, feeding on minute planktonic organisms and growing in size and complexity. Over time, it undergoes a series of metamorphic changes and eventually transforms into the next stage of development, known as the brachiolaria. This transformation typically occurs within a few weeks.

   Bipinnaria larvae play a crucial role in the life cycle of starfish, as they help disperse and distribute the species by being carried by ocean currents. They serve as an essential link between the adult starfish and their reproductive processes, aiding in successful reproduction and maintaining the population dynamics of these marine organisms.

   In summary, bipinnaria is a larval stage in the life cycle of certain starfish and other echinoderms, characterized by its bilateral symmetry, cilia rows, and swimming behavior.

Etymology of BIPINNARIA

The word Bipinnaria has its origin in Latin. It is derived from the Latin words bi- meaning two, and pinnatus meaning feathered, winged, or plumed. The term Bipinnaria was coined in reference to a larval stage observed in certain organisms, primarily echinoderms such as starfish and sea urchins. The larvae of these organisms have two rows of feather-like projections known as cilia, which resemble wings or feathers, leading to the name Bipinnaria.
