NECTOCALYX Meaning and
Definition
-
A nectocalyx is a specialized structure found in certain marine organisms, specifically in the phylum Ctenophora, which are commonly known as comb jellies or sea walnuts. The word "nectocalyx" is derived from the combination of two terms: "necto" meaning swim or propel, and "calyx" meaning cup or cup-shaped structure.
The nectocalyx is the primary distinguishing feature of ctenophores, serving as their main locomotory organ. It is a gelatinous, bell-shaped structure composed of a transparent, semirigid substance called mesoglea. The radial canals of the nectocalyx extend from the center to the periphery of the bell, giving it a distinct comb-like appearance. These canals are lined with specialized cells called colloblasts, which are responsible for capturing prey.
The nectocalyx allows ctenophores to move through the water with graceful and rhythmic motion. By contracting their nectocalyx muscles, they generate propulsion and forward movement. The beating motion of the cilia on their comb rows enables them to swim and change direction. Comb jellies use their nectocalyx to navigate their habitats, capture small organisms, and evade predators.
The nectocalyx is an essential structure for the survival and ecological function of ctenophores. It is an impressive adaptation that showcases the remarkable diversity and complexity present in marine organisms.
