Oositidae

Oositidae is a family of marine gastropod molluscs, commonly known as false limpets or saddle shells. These molluscs are characterized by their limpet-like shells, which are typically conical and not coiled. However, unlike true limpets, Oositidae possess a distinct internal anatomy that differentiates them. They are found in shallow to moderately deep marine waters, inhabiting rocky substrates where they graze on algae. The family contains several genera, with the most well-known being the genus Oosita. The shells of Oositidae can vary in size and color depending on the species and their environment. These molluscs are sessile for much of their adult lives, attaching firmly to surfaces to avoid being dislodged by wave action. Reproduction in Oositidae typically involves external fertilization, with eggs and sperm released into the water column. The larval stage is planktonic, allowing for dispersal to new areas. While not extensively studied compared to some other marine gastropod families, Oositidae plays a role in the benthic ecosystems where they are found. Their ecological niche involves consuming algae and serving as a food source for various predators.
