The Reflexed Jewel Box, scientifically known as Chama pacifica, is a captivating marine bivalve mollusk, recognized for its intricate and alluring shell.
Description & Characteristics
The Chama pacifica boasts a distinctive shell, characterized by its robust, thick structure and intricate, often colorful patterns. The shell, typically measuring up to 10 centimeters in diameter, displays a reflexed, or curved, shape, lending to its common name. This curvature allows the bivalve to securely attach to its surroundings, ensuring its stability in the often turbulent marine environment. The outer surface of the shell is frequently adorned with a mosaic of vibrant hues, showcasing a kaleidoscope of colors, including shades of orange, red, and yellow. These vibrant hues add to the visual appeal of the Chama pacifica, making it a captivating presence on the ocean floor.
Habitat and Occurrence
The Chama pacifica is a widespread and adaptable species, thriving in a variety of marine environments. It is commonly found clinging to coral reefs, where its presence enhances the ecosystem’s biodiversity. Its resilience extends to lagoons, rocky reefs, and seaward-facing reefs, showcasing its ability to flourish in diverse habitats. This species is primarily found in the Subtidal, sublittoral, infralittoral, and deep zone of the oceans, ranging from the lower limit of the intertidal zone to the shelf edge at about 200 m water depth, often classified as the neritic zone. This wide distribution highlights its role in maintaining the delicate balance of these marine environments.
Taxonomy
The Chama pacifica belongs to a fascinating family of marine bivalves known as the Chamidae. These bivalves, classified within the Order Venerida, are distinguished by their unique ability to cement themselves to hard surfaces. The Chama pacifica itself is categorized within the Class Bivalvia, a class that encompasses a diverse array of shell-bearing mollusks.
Feeding
The Chama pacifica is a filter feeder, relying on the currents to bring it a steady supply of sustenance. It meticulously sifts through the water, capturing plankton, tiny organisms that are essential for its growth and survival. This feeding strategy positions the Chama pacifica as a vital component of the marine food web, playing a crucial role in maintaining the delicate balance of its ecosystem.
