Finding Nudibranchs and More at Turtle Town: Scuba Dive

  Art in nature - the wrapped up arms and spines of a crown-of-thorns sea star. I love spending time underwater. Especially in a place like Maui, Hawaii. I have logged hundreds of scuba dives here, all around the island. This dive took me back to one of the places where I have dove before, a place called 5 Graves or 5 Caves. Snorkel boats come here often, looking for sea turtles. But the snorkeling miss a world of small and unusual creatures living in the cracks and crevices and caves down below.
