Geographical Distribution and Habitat of Blue-Ringed Octopus
The Blue-Ringed Octopus is primarily found in the Pacific and Indian Oceans. Their distribution includes:
- Australia: Particularly in southern regions and the Great Barrier Reef.
- Japan: Coastal areas and surrounding islands.
- Philippines: Coral reefs and shallow coastal waters.
- Indonesia: Various marine habitats, including tide pools and coral reefs.
Habitat Examples
- Tide Pools: Shallow pools of seawater that form on the rocky intertidal shore.
- Coral Reefs: Diverse underwater ecosystems held together by calcium carbonate structures secreted by corals.
- Sandy and Rubble Areas: Often found hiding under rocks or in crevices.
