Tethyspira spinosa is a fascinating species of sponge belonging to the family Dictyonellidae. Its unique characteristics and widespread distribution make it a significant member of marine ecosystems.
Description & Characteristics
Tethyspira spinosa exhibits a distinctive appearance. Its body is typically characterized by a network of intricate channels and pores. The species is further distinguished by the presence of numerous, small, spiny projections that cover its surface. These spines contribute to its defense against predators and enhance its ability to filter food particles from the surrounding water.
Habitat and Occurrence
Tethyspira spinosa is a common inhabitant of the marine environment. This species is found in various marine zones, including the bathyal and abyssal zones, which are characterized by deep-sea conditions. This adaptability allows it to thrive in a wide range of environments, making it a significant contributor to the biodiversity of deep-sea ecosystems.
Taxonomy
Tethyspira spinosa is classified under the phylum Porifera, which encompasses all sponges. It belongs to the Class Demospongiae, a diverse group of sponges characterized by their intricate skeletal structures. Within this class, it is further categorized within the Order Bubarida, which comprises a variety of sponges with unique morphological features. Finally, it is placed within the Family Dictyonellidae, a group of sponges known for their intricate network of channels and pores.
Feeding
Tethyspira spinosa is a filter feeder, utilizing its intricate system of pores and channels to capture food particles from the surrounding water. This process involves drawing water into its body through the pores, extracting food particles, and expelling the filtered water through a different set of openings. The extracted food particles are then digested, providing the sponge with the necessary nutrients for survival and growth.
