If you're stuck deciding which names to vote for, this should help.
Tikis
"Tikis are spiritual figures who use their big, scary mouths and menacing expressions to frighten away evil spirits. Hawaiian tiki god statues have various headdresses, each with different meanings." —WeBeTiki.com
Volcanoes
"Volcanoes are monuments to earth's origin, evidence that its primordial forces are still at work. Volcanoes are also prodigious land builders. Kilauea and Mauna Loa, two of the world's most active volcanoes, are still adding land to the island of Hawaii." —National Park Service
Destroyers
"A destroyer is a fast and maneuverable yet long-endurance warship. Hawaii's Naval Station Pearl Harbor is currently home to seven United States destroyers." —Wikipedia
Akua
"The gods who created everything and keep everything working." —MythHome.org
Honu
"The Hawaiian green sea turtle (Chelonia mydas) is the most common sea turtle in Hawaiian waters. The honu grows to an adult breeding size of 200 pounds or more." —Malama na Honu
Emeralds
"Gems native to Hawaii include peridot, obsidian and gem-like crystals called olivine, which contribute to Hawaii's green beaches. These gems are formed through cooling lava, as well as heat and pressure." —eHow
Emeralds are not found in Hawaii so the name would be more symbolic of the islands' greenery.
Koa Warriors
"The Hawaiian Koa warriors were the elite fighters of the islands. Their name originated from the tree they would use to fashion their weapons, the Koa tree." —Legends & Chronicles
The word "koa" also translates as brave, fearless or bold.
Eels
"All of the eels in Hawaiian waters are known by the Hawaiian term puhi, which is often qualified with another descriptive term. In ancient Hawai‘i some eels were considered ‘aumakua (spiritual guardians)." —Hawaiian Encyclopedia
