10 Fun Facts About Jellyfish

There are two schools of thought when it comes to jellyfish. When seen in an aquarium, like the fabulous Maui Ocean Center, they are stunningly beautiful. Watching them glow and glide is a sight to behold. On the other hand, when you’re wading waist deep in the ocean and spot a jellyfish, your first thought is usually to high tail it out of the water like you’ve just seen Jaws. It’s true the sting of some jellyfish can be nasty. Generally, though, Maui’s waters are pretty clear of the largest stinging jellies. On the Hawaii Ocean Project Lanai Snorkel and Dolphin Tour, we avoid snorkel locations with stinging jellyfish. Here are 10 fun facts about jellyfish…

Achilles Tang
These blackfish have a distinctive orange patch near the tail and some seriously beautiful orange, white, and blue stripes that look like they were painted on. Growing to 10 inches long, the Achilles Tang can be found in surge zones, along rocky shores and coral reefs. While you should always try to keep a respectful distance from fish while snorkeling, it’s especially true of the Achilles Tang, as their tails consist of sharp spines that can cause deep wounds.


Fishing on Maui: HOP to it

Some people come to Maui for the beach, others for the hiking, most for relaxation. But if you’re coming to Maui and want to try your hand at fishing, there are some things you need to know. In this article, we’ll talk about regulations, where you might want to fish and finally, what you may be catching. Please note, this article is by no means comprehensive. Rather, it’s a place for you to begin your research. Let’s dive in…


10 Facts about Sharks in Hawaii

When you visit Hawaii, you’re probably going to be spending a lot of time in the water. Visitors often ask about sharks, as in “should I be worried about them?” The fact is, many more people run into personal health-related issues while in the ocean (shortness of breath, increased heart rate) than shark-related issues. That’s not to say you should ignore the dangers of sharks. Most sharks around Hawaii’s shores are safe, but sharks are wild creatures and like all animals in nature, must be respected. Here are 10 facts about the sharks in Hawaii.


Five Turtles You Could See on Maui

Turtles are the rare creature you can see both underwater and on shore. While you’re more likely to spot turtles, on Maui at least, in the water, if you know where to look you can see the largest of them, green sea turtles, resting on the beach. Hawaii is home to three native sea turtle species and has a total of five sea turtle species in its waters. Here are the types of sea turtles you may find while wandering and snorkeling around Maui, listed in order of the likelihood of you spotting one.


10 Facts about Rays in Hawaii

One of the most exciting fish to see while snorkeling in Hawaii is a ray. A distant cousin of the shark, rays can often be seen in Maui’s waters fairly close to shore. Highly photogenic, seeing rays is always the highlight of any snorkeling adventure. Here are 10 facts about these lovely fish.

  1. Hawaii is home to three types of rays: manta, stingray and spotted eagle. The manta ray is the most common, especially near shore.
  2. The manta rays you’ll see near Maui’s shores average 5-to-8 feet, but can reach over 14 feet.
  3. Rays have been around in their modern form for at least 20 – 25 million years. Manta rays, however, have only been around for about 4.8 million years.
  4. Because manta rays can be identified individually by researchers because of the distinctive spots on their bellies.
  5. Manta rays have the largest brains amongst the 32,000 species of fish.
  6. The “stinger” on a manta ray does not work. So no fear of being injured (from the tail, anyway) of a manta ray. However, should you come across the aptly named stingray, watch out. Their tales are still very much venomous.
  7. The easiest way to distinguish a manta ray from a stingray is by color. Manta rays are black, while stingrays are brown. Stingrays also sport shorter tails.
  8. If you’re one of the lucky ones who sees a ray breach (leap from the water), the ray you’re most likely seeing is a spotted eagle ray. They are known for the colorful (white, yellow and green) dots on their backs, which contrast nicely against their black skin.
  9. Rays are distant cousins of sharks. Like sharks, instead of bones, their vertebra is made of cartilage. They also must constantly swim in a forward motion to pass oxygenated water through their gills. They cannot swim backwards.
  10. As of 2009, manta rays in Hawaii’s waters are protected against killing and capturing. Offenders will receive criminal penalties and fines of up to $10,000.

10 Facts About the Hawaiian Monk Seal

We love our monk seals. But if you’re lucky enough to see one, remember to keep your distance. They are endangered and should not be touched or harassed in any way. Beyond that, Hawaiian monk seal mothers of newborns will aggressively protect their pups. The National Oceanic Atmospheric Association (NOAA) recommends keeping a distance of 150 feet, allowing them to remain undisturbed.

  1. The official state mammal of Hawaii, the scientific name for the Hawaiian monk seal is Neomonachus schauinslandi. The Hawaiian name is “Ilio holo I ka uaua”, which translates to “dog that runs in rough water”.
  2. The average lifespan of a Hawaiian monk seal is 25 to 30 years. Adult males grow to about 7 feet long and weigh between 300 and 400 pounds. Meanwhile, females can grow to 8 feet long and can weigh between 400 to 600 pounds.
  3. The Hawaiian monk seal is unique in that they live in a tropical climate. Most seals prefer frigid water.
  4. Hawaiian monk seals do not have external ears and they cannot rotate their hind flippers underneath their bodies.
  5. Breeding season is between June and August, with birth usually occurring between March and June. The average gestation time is nine months. Mothers of newborn pups are devoted to their offspring while nursing. For the first 5-to-6 weeks of a newborn’s life, the mother is so busy safely raising her pup that she will not eat. The pups go from 35 pounds at birth to roughly 175 pounds while being nursed. The mothers, though, will lose hundreds of pounds during this time. Once finished nursing her pups, the mothers will abandon their offspring and head out to the ocean to feed.
  6. Hawaiian monk seals feed primarily in deep water coral beds on fish, lobster, octopus and squid.
  7. Humans are the biggest threat to Hawaiian Monk Seal survival. Though we don’t outright hunt them, they will often get entangled in fishing nets and gear. We also encroach on their coastal resting places. Tiger sharks and Galapagos sharks are known to prey on them. Finally, male Hawaiian monk seals will often group up and kill or injure females and immature monk seals of both sexes during a mating ritual called “mobbing”.
  8. Native to Hawaii, the Hawaiian monk seal and the Hawaiian hoary bat are the only two mammals endemic to the Hawaiian islands.
  9. The Hawaiian and the Mediterranean monk seals are the last two surviving monk seals in the world. The Caribbean monk seal, which was once the third type of monk seal, was declared extinct in 2008. In 2016, it was estimated there are 1,400 Hawaiian seals in existence.
  10. The Hawaiian monk seal was officially declared an endangered species in November, 1976.

10 Facts About Spinner Dolphins

Seeing whales on a whale watch tour is awesome. No doubt about that. But do you know what else is awesome? Seeing dolphins! One of the best ways to see them is on our snorkel tour to Lanai. Spinner dolphins, the type you are most likely to see around Maui, are considered one of the most athletic sea mammals for their amazing aerial leaps.. Here are 10 facts about these beautiful creatures.

  1. The scientific name for spinner dolphins is stenella longirostris.
  2. There are four sub-species of spinner dolphins and they are often called long-snouted dolphins. The spinners in Maui’s waters are often referred to as Gray’s dolphins (named for John Gray, the researcher who first described them in 1828) or Hawaiian spinner dolphins.
  3. Hawaiian spinner dolphins feed mainly on small fish, squids and shrimps. They feed at night and will often dive over 250 yards to eat.
  4. Female spinners reach sexual maturity between 5.5 and 10 years, while the males can reproduce between 10 and 12 years old. The gestation period for the dolphins is 10 months
  5. Hawaiian spinners are primarily three colors. The skin on the dorsal area is a deep gray, while its sides are a lighter shade of gray. The bottom portion of the dolphin is white. The dorsal fin area has small white spots.
  6. Because dolphins need to consciously think about breathing, when they sleep only half of their brain rests at a time. The awake half needs to tell it breathe and monitor its surroundings.
  7. Though the dolphins primarily breathe through their blowholes, Hawaiian spinners have developed a method of breathing without surfacing from the water. They blow a bubble when near the water surface and then quickly draw breath from it. Dolphins are so smart!
  8. When spinning, the dolphins can make up to seven complete rotations in the air!
  9. Though no one knows for sure, it’s believed the dolphins spin for the following reasons:
    • To clean their bodies of parasites (this is the most common assumption)
    • For courting members of the opposite sex
    • To communicate with other dolphins
    • For fun!
  10. Besides spinning, they are also known to do full aerial somersaults(!), head slaps, tail slaps, and spyhops (when they stick their heads out of the water to take a peek).

Dolphins, Sharks and Whales You May See in Maui

We often get asked what types of whales, dolphins and sharks are spotted here in Maui. This is not a complete list, just the ones that are most often seen from Maui’s shores and while on whale watch and snorkeling tours.

Spinner Dolphins (Very common)
We consistently see spinner dolphins on our Lanai snorkel tours, where they will play in the wake of our boats. These friendly dolphins are generally 4-to-7 feet in length and weigh between 50-to-170 pounds. The spinner dolphins of Maui feed at night, primarily on small fish, squid and shrimp.


Bottlenose Dolphins (Somewhat common)
Though similar looking to spinner and spotted dolphins, bottlenose dolphins are much larger in size, ranging from 6-to-13 feet and weighing up to 660 pounds. They also have a thicker, shorter rostrum (beak) that old-time sailors thought looked like a gin bottle, hence its name. Grey up top and white on its belly, the bottlenose dolphin is difficult to see from both above and below.


Short-Finned Pilot Whales (Somewhat rare)
A member of the dolphin family, short-finned pilot whales, with their rounded foreheads and snouts, look like whales. They are mostly dark colored with light grey stomachs and throats. Short-finned pilot whales grow to about 18 feet in length and can weigh up to 6,600 pounds. They feed primarily on squid and have been dubbed the “cheetahs of the deep” for the way they chase down squid while hundreds of meters deep.

False Killer Whales (Rare)
We’ve seen a couple of false killer whales during the 2017-2018 whale season on our whale watch tours, but for the most part, these are rarely spotted in Maui. They are quite large, averaging 16 feet in length and they can weigh up to 4,900 pounds. False killer whales are black with grey throats. Like actual killer whales, false killer whales will hunt other marine mammals.


Blacktip Reef Sharks (common)
Growing to an average length of about 6 feet, blacktip sharks are easily identified due to their, wait for it… blacktipped fins. They tend to feed most often at dawn and dusk, mainly on shellfish, squid, octopus and bony fish. There have been very few incidents involving human/blacktip interactions and no fatalities.


Whitetip Reef Sharks (common)
The whitetip reef shark is the only shark in Hawaii with the ability stop swimming and rest for long periods of time. They generally do this in caves or under ledges. They can grow up to 6 feet long and are not considered dangerous to humans.



Hammerhead Sharks (rare)
In Hawaii, hammerhead sharks have been seen up to 14 feet in length, though they tend to average out at about 7 feet. Here on Maui, hammerhead sightings are far less frequent than the other islands where they give birth and raise pups. They are most commonly seen while scuba diving off of Molokai. When they do come close to shore on Maui, they warrant beach closings. The last occurring in November, 2016.


Whale Sharks (rare)
Though rare, there were two prominent sightings of whale sharks in Maui in 2017, both occurring near Molokini. Whale sharks are the largest fish in the sea, weighing up to 21 tons and measuring out from 18′-to-33′. They feed by swimming with their mouths open and filtering everything that comes into its path.


Humpback Whales (Common)
Whale season in Maui refers to when the humpback whales visit our waters. Officially, it runs from December – April. Though in 2017, the first humpback whales appeared in October and whale tours started in earnest in early November. Humpback whales are the fifth largest whales in the ocean, growing up to 60 feet long and weighing between 25 and 40 tons. To learn more about humpback whales, we ran a full series of articles:
