A new study reveals that sea otters use tools like rocks to break open hard-shelled prey, which allows them to consume larger food items and minimizes tooth damage. The research also found that female otters use tools more frequently than males.
About sea otters
| Aspects | Description |
| About | Sea otters belong to the weasel family and are aquatic animals. They are found along the coasts of the Pacific Ocean in North America and Asia. |
| Habitat | Sea otters spend most of their time in the water but occasionally come ashore to sleep or rest. |
| Physical Characteristics | They have webbed feet and water-repellent fur to stay dry and warm, with nostrils and ears that close in the water. |
| Diet | Sea otters typically consume about a quarter of their body weight daily, mainly foraging in kelp forests and seagrass beds. |
| Ecological Role | 1, Keystone Species: The health of sea otters is indicative of the overall health of nearby ecosystems and other marine species. 2. Ecosystem Impact: They prey on sea urchins and with this sea otters maintain the population balance of these creatures. This prevents the overpopulation that can destroy kelp forests. 3. Kelp Forests: They play a crucial role in preserving kelp forests, which are essential for the survival of various marine species by providing shelter and food. 4. Biodiversity: Their presence helps sustain the biodiversity and overall health of marine ecosystems. |
| Conservation Status | IUCN Red List: Sea otters are classified as Endangered. |
