👉 Ostracodinium is a group of marine invertebrates that include the ostracods, which are marine gastropod mollusks. These crustaceans have no backbone and are adapted for life underwater, with their shells protecting them from predators and helping to filter waste products. They can be found in all types of environments, such as saltwater or freshwater, and they play a crucial role in the food chain by filtering out nutrients from the water.
