  • Role in Ecosystem Conservation:
    • Keystone Species: Vital for maintaining marine ecosystem balance.
    • Kelp Forest Protection: Preys on sea urchins, preventing their overpopulation and subsequent destruction of kelp forests.
    • Biodiversity Sustenance: Supports marine habitats by ensuring a balanced food web, aiding species diversity.
