Despite their widespread presence, spinner dolphins face several threats from human activities. They are often caught in fishing nets, and their habitats are endangered by pollution and climate change.
-
Listed as "Data Deficient" by the IUCN, the exact population size of spinner dolphins is unknown, complicating conservation efforts.
-
Noise pollution from boats and ships can interfere with their echolocation, making it difficult for them to communicate and hunt.
Unique Behaviors and Adaptations
Spinner dolphins have developed unique behaviors and physical adaptations that enable them to thrive in their aquatic environment.
