Learn about the Crown-of-Thorns Star

The crown of thorn Starfish are found on nearly every site we visit on the Kohala Coast. Divers often ask us after a dive "What was that cactus looking thing" or "was that a weed on the coral?" Read on for some info on these interesting invertebrates. 




By  Dominic S. Romer

Dive Master

While enjoying the reefs of Hawaii and all their marine life, spare a thought

for the corals on today’s menu!

The diner is Acanthaster planci , Crown-of-Thorns star (COTS) and his

favorite meal is coral polyps, especially those of Pocillopora meandrina

(Cauliflower coral).

The body is disc-shaped, up to 18” across, with as many as 21 arms, it’s

usually red/green in color and the whole thing is covered in venomous

spines. Don’t get too close...many divers will tell you of their discomfort

having inadvertently got too friendly with this star (burning pain, numbness

and possible discoloration of the area for a couple of days)!







They are impressive creatures, using all of those arms to climb atop coral

colonies where they then extrude their stomachs and secrete enzymes to

liquify & digest individual coral polyps. Just the white coral skeletons

remain, when they absorb the available nutrients and move on. True horror

movie stuff!



While these stars have wreaked havoc on some reefs around the world

(including the Great Barrier reef), here in Hawaii we don’t appear to have a

big issue with them yet and usually, one won’t see more than a few at any

one site. In places where they have become a real issue, divers can

physically remove the creatures or inject them with household vinegar to kill

them...although either option is time consuming & costly.

There are some in Hawaii who believe that this predator may in fact be

doing some good for the reef, feeding on some of the faster growing corals

(such as Cauliflower & Rice corals) and increasing coral diversity on

Hawaiian reefs.

In Hawaii, their main natural predator is the Triton’s Trumpet snail; also

Harlequin Shrimp, Stripebelly Pufferfish and Lined Fireworms will feast on

this star.



We hope you will get a chance to observe this impressive star, when diving

with us at Kohala Divers in Hawaii!

Divers Who Defog: Your Glasses!

Is this you?!?! Do you exhale in your socially-distant mask and fog your glasses? Well, the people who de-fog your scuba mask have some advice:


1) Start with a clean pair of glasses. This goes for your scuba mask, too! Use your dish soap: It is a fabulous de-greaser! Clean both inside and outside lenses, nose-piece, ear wands... all of it. Leave to dry or dry with a soft micro-fiber cloth.

2) A close fitting nose piece on your mask will reduce the fog exiting the top of the mask onto your glasses. Re-bend your nose wire (if it has), use a buff, situate it a little lower on your nose bridge (but still wear it properly! Cover those nostrils!)


3) When I know I will spend all day in glasses/mask combo, I clean my glasses that morning!


4) Our goggle/eyewear defog spray is made for this purpose: Spray both sides and clean dry with a cloth. DO NOT USE concentrated scuba defog, meant to be used with water! Check the print on your defog: Goggle defog is already watered down for use that close to the eyeball.

5) Hey! While you are at it, get your scuba mask out and give it a clean! Use that same dish soap! Then allow to dry and store in it's box. If you have a neoprene mask strap, remove it from the mask while in storage: Neoprene off-gasses and discolors silicone mask skirts. We will be back using that spotless and non-discolored scuba mask in no time at all! Promise!

In the market for a warm wetsuit? A testimonial by a picky, temperature wimp, of a diver.


Testimonial on my New ScubaProEverflex Wetsuit -by Rebekah 




I love getting new dive gear! But I have to admit when getting into the territory of wetsuits it is not as easy as liking the features and picking a color. It's almost like bathing suit shopping but maybe worse. There are so many different body styles that fit differently in wetsuit styles. Then there's the warmth factor which is the whole purpose. 

Staying warm underwater is my #1 priority in a suit. I like to do long dives and not move much so I can take in all the hiding little critters and feel totally relaxed when diving. A 3mm won't cut it in my world so for me I am always shopping for a 7mm. Over time and deeper dives a suit compresses. I begin with a thick suit and by the time it retires, it is maybe 3mm to 5mm. With a thicker suit comes the awkward trade off of being incredibly hard to put on and usually feels as if a boa constrictor is wrapped and ready to squeeze out your nitrogen bubbles. Hardly pleasant! That's where my testimonial on this suit begins.

  When my women's size medium arrived I was pleasantly surprised when it slid on like satin. Very comfortable and I could even walk and raise my arms above my head! "Uh-oh", I thought, "This is too comfortable! It won't keep me warm!". My next dive day I suited up and was glad Captain Stephen gave me the pro tip to fold the glideskin leg and arm seams in to trap water as it came in. When I checked my dive time at an hour 5 minutes and realized I hadn't even shivered or felt that chilling trickle of icy water down the neck. I was impressed. 


Features I Love 
The warm 2016 blue liner that traps body heat. 
Neck zipper to give comfort when suited up and waiting to get in.
Ankle and wrist zippers.
Easy to put on glide skin.
Fits true to size (See size chart below).

Fish Geek's Pick-Of-The-Week! Flame Angel

Flame Angel by Scott Rettig

Flame Angel

Latin: Centropyge loricula
 A beautiful angelfish of bright red and orange with dark black bars or even zebra stripes, the Flame Angel is one of the more strikingly beautiful fish on the reef. Usually from 2 to 4 inches in length, the Flame is very shy, often darting into the safety of hard finger corals and hiding until the threat is gone. Hoover notes that the blue fringe is more pronounced in males, while Randall notes that the first of the 3 to 7 stripes is often a wider spot. Spawning occurs in pairs, but one male may have a harem of two females.
Scott  says, "One of my favorites to find on the reef, the Hawaiian Flame Angel has comparatively less orange than it's cousins around the world."
John P. Hoover agrees, noting "True Hawaiian Flames [have] brighter red between the bars".
"I call her 'Lips' " by Scott Rettig


When we are lucky enough to find one of these (often territorial) fishes on the reef, we quickly make the hand sign (like flicking a Bic lighter), then gently rise further away from the fish, giving it space. If we can resist the urge to rush it, or chase it into the reef, then this shy fish may just poke his nose out and allow the patient diver a nice glimpse.

Kama'aina? Not endemic. 
Size: From about 2" to about 5"
Depth:Safe hard coral areas from 30' to 100'.
White List? No. Cheaper to catch elsewhere in the Pacific.

Fish-Geek's Pick-Of-The-Week: Hawaii's Sea Monster

Sea Monster

Meerwunder vnd seltzame Thier / wie die in den Mitnächtigen Ländern / im Meer vnd auff dem Landt gefunden werden (taken from the vignettes on Olaus Magnus's Carta marina), Basel c. 1544, 34 x 28 cm
Latin: Cetus, Serpus Marinus
Greek: Ketos
Hawaiian: KoholaLoa

"A man by the name of Mapua, and others, were out fishing, with their boats anchored. They saw a great thing coming up, rising high above the surf, fire burning on top of it. They thought it was something evil and hurried to the shore, trembling and frightened by this wonderful apparition. They had fled, leaving all they had used while fishing. When they went up from the beach they told the high chief Kaeo and the other chiefs about this strange sight." Hawaiian Historical Legends by William D. Westervelt 1923
Local legends tell of a huge sea monster that has lived on the Kohala Coast for generations, and here, on our Fish-Geek's Pick-of-the-Week, we spill all about this mysterious monster, with legends confirmed by our very own crew. 
What do you think this is? From Bishop Museum, Honolulu
 Historian Geoff Dobson says, "It has been reported that Captain Cook’s HMS Endeavour in the South Pacific was attacked by a sea serpent that had to be beaten off by the crew."
Up the street from our very own dive shop, rises a huge Heiau (temple) by the name of Pu'ukohola- Whale Pu'u... or is it really named as the lookout post for the Sea Monster? Right below it is the "Shark" Heiau, Hale o Kapuni, which was hastily covered over by the US Military, some say to bury the truth about the ritual feeding of virgins to the vicious beast. Further rumors confirm a mysterious pre-Cook Portuguese ship sunk by the monster right off the Kohala Coast. Full of Portuguese gold and perhaps proof of earlier European visitation, it is currently the subject of a massive treasure hunt and Sea Monster hunting expedition.

Obviously the coiled lengths of a nasty sea monster. Photo by Kelleen Lum
 I can see you are skeptical, so let's not rely on proven Historical record: Read, if you dare, the quotes from our own crew about their encounters with the Leviathan:
Captain Bob confirms, "I have seen [it] erupt from the deep- that deep ledge where the huge shrimp are?- with a huge mouthful of shrimp, [it's] breath was horrible!"
Captain Greg nods and adds, "[The Monster] steals our fish right off the hook from our fishing boat lines. Just leaves the bloody hooked head behind!" 
You can believe them: They are fishermen and they always tell the truth.We also know what the Sea Monster eats: Shrimp from the deep, like Bob has witnessed, headless fish right off the line, the occasional unlucky solo kayaker, chewy sacrificial virgins, and yellow tangs by the mouthful- How else to explain how so many have gone missing? The Kohala Coast used to be called "The Gold Coast" because of all the thousands of yellow tangs coloring the waves yellow. Obviously the Sea Monster is eating them all.
From James J. Williams Collection Hawaiian Historical Society
Finally, we know where it is currently living:
Kelleen says, "I heard that there is a sunken Mahukona Sugar train that tumbled off a train trellis into the sea. If we can find it, imagine the wreck dive that would be? But it probably has [a sea monster]...living...in it." 
The many train cars would be a perfect fit for it's huge serpentine coils.
More crew testimonials:
Tina says, "Puff the Magic Dragon, who lives by the sea, was[n't] about a dragon in Hanalei Kauai, [but] obviously a reference to smoking [nostrils] and burning [eyes of] da kine Hawaiian green [sea monster]."
When asked about the Sea Monster, Robyn replied,
"Don't talk about Scott that way!"
Upon reading this list of true and proven facts, Historical record and crew testimonials, Flipper exclaimed:
"This is the biggest load of crapola, mis-information, and downright lies that I have ever seen. Frankly I am shocked- shocked!- that we would allow this pile of bull-[explicative] out there for our trusting divers to read. It is irresponsible yellow journalism! Everyone knows the season for Sea Monsters is summer, not April 1st!"

Kama'aina? Yes. Although relatives have been spotted in Scotland, Vermont, etc.
Size: Ginormous! Like Scary-huge!
Depth: Surface to Davey-Jones'-Locker deep.
White List? No. Not safe for Aquariums.
