Abstract

Marine mammals are among the most charismatic and ecologically significant creatures in the world’s oceans. These species, which include whales, dolphins, seals, and sea otters, play vital roles in maintaining the balance and health of marine ecosystems. From regulating prey populations to contributing to nutrient cycling and supporting biodiversity, marine mammals are integral components of their habitats. This article explores the diverse roles of marine mammals in the marine food web, their impacts on ecosystem functioning, and the challenges they face due to human activities and environmental changes. In addition, the article examines the importance of conservation efforts to protect these animals and ensure the health of marine ecosystems. By understanding the complex interdependencies between marine mammals and their environments, we can better appreciate their value in the broader context of ocean health and biodiversity preservation.
