Marine predators are animals that hunt and feed on other marine organisms. They play a crucial role in maintaining the balance of ocean ecosystems. Common examples include sharks, orcas, and sea lions, which use various hunting techniques to capture their prey, such as fish, squid, and seals. These predators are often at the top of the food chain, helping to regulate the populations of other marine species. Their presence indicates a healthy marine environment, as they contribute to biodiversity and the overall stability of ocean habitats. Understanding marine predators is essential for conservation efforts and sustainable fishing practices.
