Are Hawaiian Monk Seals Aggressive? There are several myths surrounding the Hawaiian monk seal, a species that is at grave risk of extinction. One frequently asked question is whether the Hawaiian Monk Seals are aggressive. Let’s investigate these unusual marine mammals to get the truth.
The Hawaiian Monk Seals
Neomonachus schauinslandi is the scientific name for the Hawaiian monk seal. The German scientist Hugo Schauinsland, who discovered the species’ skull on Laysan Island in 1899, is credited with giving it its scientific name.
Its short-haired neck folds, which resemble a monk’s robe, have earned it the nickname “monk seal.” Other Hawaiian names for this seal include na mea hulu (the furry one), iliokai (seadog), and ilioholokauaua (dog running in rough seas).
Hawaiian monk seals can live for almost 30 years, reach a length of 6-7 feet, and weigh 400-600 pounds. The only way to distinguish between men and females is to look at their genitalia, as they are often the same size.
Although born black, they gradually develop light gray or yellowish brown on their bellies and dark gray or brown on their backs.
They go through a “catastrophic molt” in a year or so, during which they lose their outermost coat of skin and hair.
The Hawaiian monk seal is easily recognized by its natural bleach marks or scars, and many of them have identification tags on their back flippers so that conservation groups may follow them as well.
As “generalist feeders,” Hawaiian monk seals consume a variety of foods, including eels, crabs, octopuses, squids, and common fish.
They search for prey near the seafloor since they can hold their breath for 20 minutes and dive more than 1,800 feet.
Hawaiian monk seals also favor a more solitary lifestyle than other seals that reside in colonies. Between March and August, seals give birth on sandy beaches after mating in the water.
Seals typically give birth to one pup per pregnancy, and the gestation period lasts between 10 and 11 months. Before the puppies go out to graze on their own, mothers tend to them for a few weeks.
Evolution
The Hawaiian monk seal is one of two species of earless seals that belong to the Neomonachus genus. Human interference in its habitat has led to the extinction of its other near relative, the Caribbean monk seal.
One rung up its evolutionary tree is the Monachini, the tribe to which the Hawaiian monk seal belongs. This tribe is home to the Monachus genus in addition to the Neomonachus genus.
The Mediterranean monk seal, or Monachus monachus, is the only species in this second genus.
Although the Hawaiian and Caribbean diverged into distinct subspecies approximately 4 million years ago during the early Pliocene, experts believe that the Monachini split into distinct genera 6.3 million years ago during the late Miocene, making this family of earless seals real seals.
Are Hawaiian Monk Seals Aggressive?
In general, Hawaiian monk seals do not act aggressively toward people. But it’s important to keep in mind that these are wild creatures, and once they feel threatened, they may turn protective.
1. Mother Seals Are Protective: Mother seals’ protection of their young is the main source of hostility.
When a seal mother becomes overly protective of her pup, she may act aggressively toward anyone who approaches too closely.
2. Keeping Your Distance: It’s important to keep a safe distance from monk seals, particularly if they are mothers with young. A minimum distance of 150 feet is advised.
3. Observing from a Distance: Using binoculars or a spotting scope, you can safely observe these amazing animals from a distance.
What Does Hawaiian Monk Seal Eat?
Ocean meat is the only food consumed by Hawaiian monk seals. Being huge mammals, they rely heavily on octopus, lobster, bony fish, crab, eel, and squid for nourishment.
Because they stay on land and don’t feed again for six weeks after the pup is born, when weaning usually takes place, females must gain 100 to 200 pounds throughout the mating season and during pregnancy.

Threats that Hawaiian Monk Seal Faces
The main Hawaiian Islands are home to about 400 of the 1,600 estimated remaining seals in the wild, while the northwest Hawaiian Islands are home to 1,200.
Unfortunately, within the past 25 years, this population has significantly decreased. The Hawaiian monk seal is seriously threatened by humans in several ways.
This population suffers from intentional slaughter, sleep disturbance, intentional feeding, and boat strikes, all of which are caused by humans.
Seals commonly give birth on well-known tourist beaches, posing a risk to both humans and other seals because seal mothers are fiercely protective of their young.
The number of Hawaiian monk seals is also threatened by food shortages. They have to fight for food with sharks and other huge marine predators in some areas.
The availability of food is also impacted by climate change since the temperature of the water determines what kinds of marine life can survive in particular areas.
Shark attacks are another danger to these seals. Galapagos sharks can sometimes hunt pups in shallow water; however, this is rare.
Conservation Efforts
Numerous hazards confront the Hawaiian monk seal, one of the world’s most endangered seal species. To secure their existence, however, concerted conservation initiatives are in progress.
Habitat Protection:
- Monk seal habitat is vitally protected by the establishment of the Papahānaumokuākea Marine National Monument, one of the world’s largest marine conservation zones.
- The goal of ongoing initiatives is to reduce human disturbance in these protected areas.
Reducing Human Impact:
- It is important to limit human contact with monk seals.
- This entails restricting vessel traffic in vital areas, reducing the entanglement of fishing gear, and educating the public on the value of treating these animals with care.
Disease Prevention:
- Monk seals are being protected from illnesses like morbillivirus through the use of vaccination programs.
- To better understand and lessen the effects of illnesses on monk seal populations, research is still being conducted.
Rehabilitation and Release:
- Monk seals that have been rescued and rehabilitated are closely watched and, if feasible, returned to the wild.
Public Awareness and Education:
- It is crucial to increase public awareness of the Hawaiian monk seal’s predicament.
- The goal of outreach and education programs is to instill a sense of accountability and stewardship in the general population.
Finally, it’s important to remember that Hawaiian monk seals are wild animals, even though they often do not act aggressively against people.
It’s critical to respect their personal space and keep a safe distance. We can guarantee these amazing animals’ continuous existence and save these rare and endangered species for future generations by watching them from a distance and contributing to conservation initiatives.
