Spadella is a genus of small, transparent marine invertebrates belonging to the family Spadellidae within the phylum Chaetognatha, commonly known as arrow worms. Unlike most chaetognaths, which are pelagic (free-swimming in open water), species of Spadella are benthic, meaning they live near the seafloor and often attach to substrates in shallow marine…
