Hawaiian Monk Seals
Characteristics of Hawaiian Monk Seals
Hawaiian Monk Seals, scientifically known as Neomonachus schauinslandi, are an endemic species to the Hawaiian Islands and they are one of the rarest marine mammals in the world. These seals are known for their unique appearance, with a rotund body covered in short, sleek, and dark gray or brown hair. They have a relatively small head with large, round eyes widely spaced apart, and a set of large, sensitive whiskers called vibrissae. The adults can measure up to 7 feet in length and weigh between 400 and 600 pounds.
Habitat and Distribution
Hawaiian Monk Seals can be found inhabiting the remote sandy beaches and rocky shorelines of the Northwestern Hawaiian Islands. They prefer to spend their time lounging and resting on empty beaches, away from human disturbance. However, they can occasionally be spotted in the main Hawaiian Islands, especially on the less crowded and more secluded beaches. Their population is primarily concentrated in the protected areas of the Papahānaumokuākea Marine National Monument.
Diet and Behavior
Hawaiian Monk Seals are primarily carnivorous, feeding on a variety of fish, squids, and crustaceans. They are known to dive to depths of up to 1,500 feet in search of prey. These seals are solitary creatures, although they occasionally gather in small groups. They are excellent swimmers and can spend extended periods of time in the water, but they also depend on land for resting and breeding. Despite their cute and seemingly docile appearance, it is important to note that they are wild animals and should not be approached or disturbed.

Green Sea Turtles
Identifying Green Sea Turtles
Green Sea Turtles, also known as honu in Hawaiian, are easily distinguishable by their large size and distinctive features. They have a streamlined body covered in a combination of brown, black, and olive-green coloration. Unlike land turtles, their limbs are modified into flippers, allowing them to navigate through the water with ease. The average adult green sea turtle measures about 3 to 4 feet in length and can weigh up to 500 pounds.
Lifestyle and Reproduction
Green Sea Turtles spend the majority of their lives in the ocean, only coming ashore for nesting purposes. They are known for their impressive migrations, as they travel many miles between their feeding grounds and their nesting beaches. The females return to the same beach where they were born to lay their own eggs. The mating season usually occurs in the water and can be quite vigorous, with males often seen competing for the attention of the females. After nesting, the females will return to the sea, leaving the eggs to hatch on their own.
Dietary Habits
The diet of Green Sea Turtles mainly consists of sea grasses and algae, which they graze upon while gracefully gliding through the water. They have a unique and specialized jaw structure that enables them to scrape and tear the vegetation. It is estimated that an adult green sea turtle can consume up to 10 pounds of vegetation per day, making them important herbivores in the marine ecosystem.
Relationship with Hawaiian Culture
In Hawaiian culture, Green Sea Turtles hold a special place of honor and are considered sacred creatures known as ‘aumakua, or ancestral guardians. They are deeply respected and protected by local communities.

Their bodies are predominantly dark gray or black, with white undersides and distinct black and white patterns on their flukes, which are often used to identify individuals.
Migration Patterns
Humpback Whales are known for their impressive annual migrations, traveling thousands of miles between feeding and breeding grounds. Every winter, they leave their feeding grounds in colder, high-latitude waters and embark on a long journey to warmer tropical waters, such as those surrounding the Hawaiian Islands. These warm waters provide the ideal environment for breeding, calving, and mating activities. The return journey to their feeding grounds typically takes place during the spring and summer months.
Feeding and Breeding Habits
During their summer feeding season, Humpback Whales primarily feed on krill and small fish, using a technique called lunge feeding. This feeding behavior involves lunging towards a school of prey with their mouths wide open, engulfing significant amounts of food in a single gulp. However, they do not feed during their migration or breeding season, relying on the energy stored in their blubber reserves.
Breeding and mating behaviors are often an impressive spectacle to witness. Male Humpback Whales, known as bulls, compete for the attention of the females through vocalizations, breaching, and tail-slapping displays. Once a pair forms, they engage in mating activities, often accompanied by acrobatic displays such as leaping out of the water and slapping their tails on the surface.
Role in Hawaiian Mythology
The humpback whale holds deep cultural significance in Hawaiian mythology. Known as koholā in Hawaiian, these majestic creatures are believed to be emissaries that bring messages from the gods to the people. They are associated with qualities of wisdom, strength, and protection. The arrival of humpback whales in Hawaiian waters is celebrated through various cultural events, such as the Makahiki Festival, which signifies the beginning of the Hawaiian New Year and honors these magnificent creatures.
