These nudibranchs are typically found in shallow waters, ranging from the intertidal zone to depths of around 20 meters. This species is particularly prevalent in tropical and subtropical marine zones, where the warm waters and abundant food sources create a favorable environment for its survival.
Taxonomy
Halgerda biqiea belongs to the Class Gastropoda, a diverse group of mollusks that includes snails, slugs, and limpets. It is further categorized under the Order Nudibranchia, which encompasses a wide variety of colorful and fascinating sea slugs. Within this order, it is classified within the Family Discodorididae, a group characterized by their generally smooth, oval-shaped bodies and often striking color patterns.
Feeding
Halgerda biqiea is a carnivorous nudibranch, primarily feeding on sponges. These colorful invertebrates play a crucial role in the marine ecosystem by helping to regulate sponge populations. Halgerda biqiea employs its radula, a ribbon-like structure containing rows of teeth, to scrape and ingest sponge tissue. This diet allows the nudibranch to absorb toxins from the sponge, providing it with a form of chemical defense against predators.
