Diazona formosa, commonly known as the Tunicate, is a marine invertebrate belonging to the family Diazonidae. It is a fascinating creature with a unique appearance and interesting feeding habits.
Description & Characteristics
Diazona formosa is characterized by its colonial nature, forming large clusters of individuals. These individuals are typically small, reaching a maximum size of a few centimeters. Their bodies are covered in a tough, leathery tunic, which gives them their name. The tunic is often brightly colored, contributing to the vibrant appearance of the colony.
Habitat and Occurrence
Diazona formosa is an offshore species, preferring sandy seafloors in the subtidal, sublittoral, and infralittoral zones. These marine zones encompass the region extending from the lower limit of the intertidal zone to the shelf edge at approximately 200 m water depth. This range aligns with the neritic zone, which encompasses the coastal waters of the oceans. Diazona formosa thrives in these environments, where it can access the resources it needs to survive and reproduce.
Taxonomy
The species Diazona formosa is classified within the Class: Ascidiacea, Order: Aplousobranchia, and Family: Diazonidae. This taxonomic structure reflects its close relationships with other tunicates, highlighting its unique characteristics and evolutionary history.
Feeding
Diazona formosa is a filter feeder, obtaining its sustenance from the plankton suspended in the water column. This feeding strategy involves drawing water through siphons, filtering out the minute food particles, and expelling the filtered water. The efficiency of this feeding process allows Diazona formosa to thrive in its marine habitat, utilizing available resources and contributing to the overall ecosystem.
