The Hermit Octopus

My first night dive... At "The Black Rock" in Maui.
This little guy was walking across the ocean floor, decided to grab a couple shells and hide himself inside them. He's super smart... He grabs the same 2 shells and re-hides after the DM popped him out to show us... DON'T do this... Just look... The idea is... We take only photos (or video) and leave only bubbles... So I feel a bit guilty about this, but SUPER cool to have gotten to see it happen...
