Green Sea Turtles in Hawaii

Green sea turtles, known as “Honu” in Hawaiian, are a symbol of endurance and longevity. Hawaii, with its rich marine ecosystem, serves as a sanctuary for these magnificent creatures. This pillar page delves into the world of Green Sea Turtles in Hawaii, discussing their biology, cultural significance, current challenges, and conservation efforts.

Biology & Life Cycle of Green Sea Turtles

The green sea turtle boasts a heart-shaped, streamlined carapace, which varies from black to shades of green. They can grow up to 4 feet in length and weigh around 300-350 pounds when fully matured.

Juvenile green sea turtles are omnivores, consuming both marine plants and small invertebrates. However, as they grow, they shift predominantly to a herbivorous diet, feasting on seagrasses and algae.

Green sea turtles reach sexual maturity between 20-50 years. Females return to the beaches where they were born to lay their eggs, often traveling hundreds of miles. After a two-month incubation period, hatchlings emerge and immediately make their perilous journey to the ocean.

Cultural Importance of Honu in Hawaii

For Native Hawaiians, the Honu is a symbol of good luck, endurance, and long life. It’s woven into local myths, legends, and even petroglyphs carved on lava rocks. Traditionally, Hawaiians believe that these turtles are guardians or ‘aumakua, which watch over families and guide them.

Threats & Challenges

While adult green sea turtles have fewer natural predators, the eggs and hatchlings are vulnerable to birds, crabs, and other marine creatures.

Human-induced Threats:

  • Fishing Nets: Green sea turtles often get entangled in fishing gear, leading to injuries or death.
  • Pollution: Debris, especially plastics, can be ingested, leading to internal blockages or harm.
  • Climate Change: Rising temperatures influence the sex of hatchlings, potentially skewing population dynamics.
  • Habitat Destruction: Coastal developments can disrupt nesting sites.

Conservation Initiatives

  • Protected Areas – Hawaii has established marine protected areas and refuges to safeguard these turtles and their habitats.
  • Legislation – Under the U.S. Endangered Species Act and Hawaii state law, it’s illegal to harm, harass, or kill green sea turtles.
  • Rescue & Rehabilitation – Several organizations in Hawaii are dedicated to the rescue, rehabilitation, and release of injured turtles.

How You Can Help

  • Be a Responsible Tourist: If you’re snorkeling or diving, maintain a respectful distance.
  • Participate in Beach Clean-ups: Keeping beaches free of debris can help turtles during their nesting and hatching phases.
  • Educate & Advocate: Spread awareness about the significance and challenges faced by green sea turtles.
  • Support Conservation Groups: Donate or volunteer with organizations dedicated to turtle conservation in Hawaii.
