Many of the Hawaiian fish species only live in Hawaii because the island chain is so isolated that many fish species evolved here and nowhere else in the Pacific Ocean. For a fish to get all the way to Hawaii its eggs must be able to float in currents from as far away as Tahiti or Guam so over millions of years Hawaii has a lot of beautiful reef fish but not as many as most other Pacific Islands.
This six inch long bright yellow fish is Hawaii’s most abundant butterflyfish. On the deep water ledges on the island of Ni’ihau there are schools of over 1,000 milletseed butterflyfish and diving with them is like being in a yellow snow storm.
You do not want to step on this foot long fish here in Hawaii as it could send you to the hospital! What is so amazing is that very few people get stung by the devil scorpionfish even though I have seen people step right next to one sitting camouflaged right on top of the reef.
