The BenBioDen database is a big collection of information about animals that live on the ocean floor. These animals come in different sizes, like small, medium, and large. They are important for mixing up the seafloor, breaking down dead stuff, and being part of the ocean food chain. The database has data from many studies around the world, with details on how much these animals weigh and how many there are in a certain area. This database will help scientists learn more about where these animals live and how much they weigh, which is important for understanding ocean ecosystems.
