👉 Pentoffiini, also known as pentopods or pentodermata, are a group of marine invertebrates that include several families, including the Daphnia and the Ctenophora. These organisms are characterized by their unique adaptation to living in aquatic environments, with their large eyes, which enable them to see in low light conditions, and their highly developed respiratory system that allows them to extract oxygen from water through a process known as photosynthesis.
