Box Jellyfish, Pygmy Killer Whales, Reef Surveys - Bonaire ep. 42
HTML-код
- Опубликовано: 27 июл 2024
- Bonaire's deadly Box jellyfish, Pygmy Killer Whales, and reef surveys of Bonaire's northern dive sites. These are things most people will never do or see on a dive trip that volunteering made possible. In this episode you will learn about Bonaire's deadly box jellyfish and dive with them up close and personal literally a couple centimeters away at the Oil Slick Leap dive site. You will learn about the research behind the sting that led to the development of an antidote. We will then whisk you away to the northern part of Bonaire and take you on a reef health survey. In the process you will learn about reef health in these northern dive sites and have an encounter with one of the rarest marine mammals on the planet - The Pygmy Killer Whale!
Filmed in High Dynamic Range.
Correction on the moray eel larva. They are actually bonefish larva. Thank you Ellen Mueller for pointing that out.

thanks for your positive take on what is happening to our reefs. Been here 17 years,, holding out hope ...
Us too. The water temperature on Klein Bonaire dropped to 28C (82.4F) at 26 (85 feet) meters and below yesterday. More color is returning to the coral. We are hopeful.
We corrected the auto generated English subtitles. It will help with the technical terms mentioned int the video.
This is, as always, another great *A Diver's Life* Bonaire diving video. Indeed, this documentary provides very interesting and critical information on both box jellies and the current coral bleaching effects. Let's hope that these Bonaire corals make a complete recovery from SCTLD and coral bleaching. Thanks for sharing!
Thank you. You are most welcome.
Especially loved this episode, thanks for sharing.
I went to the University of Hawaii for biology and learned all about Dr. Angel Yanagihara's work in my corals class, but did not realize that Bonaire had the same species of box jellies nor that number of them!
As far as the coral health on Bonaire goes... wow, it has been so sad to see it decline so much. We first visited Bonaire around 6 years ago and it was a bit jarring to visit again last year. Even more so seeing the extent of bleaching in your video. Although it is great to learn that just maybe it will help them with STCLD and that they do seem to be bouncing back a bit for now. Hopefully that trend continues.
On our last visit we noticed way fewer fish, murkier waters, and that a lot of the fish were sick and covered in black spots, especially on the surgeonfish. If I recall, it is a parasite, but do you know if it affects the health/populations of the fish? Or why it is so prevalent?
Thanks again for sharing. Great videos!
Thank you for your kind words and watching our channel. I can’t speak with certainty about the spots. However, restricting access to the park and Klein Bonaire as well as designating red zones for SCTLD forces divers into a limited number of dive locations. We are like paparazzi. Divers going over and over the same spots. The fish move to areas with less people just like you and me. When we had Covid people could not come to the island and the fish numbers increased dramatically. There is no free lunch when it comes to protecting our reefs. I am sure rising temperatures increase the impact of diseases and parasites - even on fish.
I refer to the divers going over the same areas in this video you may have seen:
ruclips.net/video/IaL7Xctk27U/видео.htmlsi=2HiwwrNkAT0fjFGg
I'm not sure what your camera gear is but it produces some of the best high quality underwater footage I've ever seen!
Thank you! It is the Sony A7sIii. Tomorrow, RUclips should publish our HDR version which will really kick it up a notch.
@ADiversLife it's hard to believe it can get any better, but I'll take your word for it, I look forward to seeing HDR version!
@@tvelocidad the link is the same. If your device supports hdr RUclips will deliver the hdr version instead.
Are the dive shops still using the decontamination tanks to prevent the spread of SCTLD?
That was amazing how many jellies there were. I had no idea.
Yes they are. We use Detol in our tanks at home. To film in the northern areas we also disinfected the inside of our BCs. Oh yes. Lots of jellyfish. If you are going to dive locations like oil slick, Ladania’s leap, or Rappel at night just prepare ahead of time and bring sting no more. They may not show up but better to be safe. They are supposed to be selling sting no more at vip diving.
What an amazing encounter it was!😍🐋
It definitely was! It was wonderful being able to experience it with Alain and the Wageningen research team.
I understand what you're saying about the bleaching coral. But what about the cruise ships? I used to dive the south pier (11 years ago) and it was beautiful. An array of encrusting sponges and the creatures were in abundance from the Dive Inn site all the way to Buddy's reef. When I dove it last about 5 years ago I was shocked to see that it was all black goo. That's when I noticed how it spread north. It is sad to witness the demise of the coral reefs throughout the Caribbean. Bonaire was the last of the beautiful reefs in the Caribbean, The in town diving used to be some of the best diving, we would have encounters with tons of all the various types of morays, octopus, frog fish and sea horses. The rocks near the marina were also always loaded with huge green morays. Now the town dive sites are but a memory, BTW last time I was in Bonaire they had 2 cruise ships at a time. I am a fan of your clips.
I don't recall seeing a black goo but, a number of factors have hit the reefs. Hurricane Omar stripped all the marine life off the north pier. I recall when the town pier was one of the most popular dive sites in the Caribbean. Population growth had resulted in septic systems leaking into the sea. Since those 11 years the we have a new septic treatment facility and this waste is transferred inland for treatment with by the facility. However, you fix one problem and then we get hit with another. SCTLD started in Florida and now has reached us. Nutrients, coming from the Amazon rain forest have showed up in the Caribbean promoting algae growth. Climate change has effected all the seas on the planet. As I am sure you know there are other stressors. It is terribly frustrating. What I can say is that we have the most active marine management team in the Caribbean. What Doreen and I try to do is help them out when we can. Having a boat and a lot of dive experience is a good addition to their efforts when needed.
Thank you so much for watching our channel and caring about the reefs.
A real success story was the development of this box jelly antivenom. I have seen people at Oil Slick leap go in with shorts and t-shirts at night despite the presence of box jellies. Some have gotten stung and by the time the get to the top of the ladder they can't walk. Bud was there to administer the antivenom and I am sure it saved their lives. At least one person died on Bonaire from a box jellyfish sting at Oil Slic Leap. Sting No More is now being sold on the island.
I was under the impression bleaching was seasonal there? Is it worse this year? Katpata was fine in August, 40% bleached in October.
Bleaching has not been every year but when it happens it is around the same time of year. 4 years ago we had a bad bleaching event. This year was the worst we have ever seen. The reef has recovered even more since the video and it will improve as the water temperature continues to cool.
Hey, you said inhibitor. Can you tell mr what it is? Borate, perhaps?
The main antidote is copper glutinate. The complete ingredients are published by the UHawaii Medical School and AlataLabs.
