Ostracods Sexy Dance

Leave a reply

Ostracods in Bonaire – a sexy dance while diving.  A few days after the full moon an astounding phenomena happens underwater in Bonaire that is akin to an underwater firework display by tiny creatures called Ostracods!

Our friends on Ad Astra had been talking about this amazing display for weeks and so after the full moon they decided to plan another day out on their big boat, Ad Astra.  Our friends from Element joined us for a total of 10 people (7 divers).  We headed over to Klein Bonaire to a site called Sharon’s Serenity.  The plan was to dive the site during day light hours, then go back and do a second dive at night to try to witness the mating of the Ostracods.

The first dive was pretty amazing.  Matt and I headed out first and explored 23 meters below the surface to find a wide array of sea life.  We saw a small school of Hawaiian Black Triggerfish also called Black Durgon which are actually dark blue with a tad bit of green if you get up close and personal (which they wouldn’t let us).  The white strip is actually silver, but it appears to glow as they swim by.

As we were waiting for the other divers, we explored a huge coral that had a large cave or protected area (perfect for lion fish and/or lobsters) so I peered in and to my surprise there were 4 HUGE lion fish – probably 15-18″ in length hovering upside down!  I was so darn impressed and in awe of these stunning creatures that I almost forgot they are destroying the reefs.  I showed Matt and a few of the others the find and eventually swam back to the boat.  Matt and I had a good long dive, over 60 minutes at this site.

We got back on Ad Astra and enjoyed some light snacks and shared stories of what we saw below.  Just after sunset, we put our gear on again and jumped back in the water.  Since the current had picked up a bit, we decided to head to the bow of the boat toward the mooring.  A few of us were armed with flash lights so as we waited for full darkness as we explored the shallows and found several eels and lots of fire worms which are pretty spectacular at night but hurt immensely if you touch them.

We had a strong current and in an effort to minimize our movement and use less air, we decided to hold on to the mooring line to wait for the Ostracod show to begin.  We had already turned off our lamps and were truly just hanging out in 6.5 meters of water in the darkness.  We did have the moonlight and once your eyes adjusted you could see so it wasn’t total blackness.

The Ostracods (or Seed Shrimp), are tiny creatures (only a few millimeters long) live in shallow water for mating.  They belong to the Crustacea family (shrimp, lobsters, and crabs) and produce a blue glow to attract a partner.

There are many creatures that can glow, especially marine life at greater depths.  This phenomena is called bioluminescence. The glow is produced to attract a partner for mating or for signaling alarm to others. Other sea life that glow underwater are (specific types of) octopus, jellyfish, worms, plankton and deep sea fish.

Cypridinid ostracods are one of the type of Ostracods that can be found around Bonaire, the ones that produce the magnificent bioluminescence show around full moon. On land male fireflies attract mates by producing light patterns with bioluminescence, the same goes for Cypridinid ostracods underwater.

The magical mating show happens two to five days after the full moon. The glow and glitter explosion will take place 45 minutes after the sun has set and before the moon fully rises – and if and only if the Ostracods have NOT been disturbed by any light (dive torch, street light, lights from buildings, etc).

While we were waiting for the Ostracods to start mating we experienced a pretty cool display of bioluminescence ourselves.  We started to wave and clap our hands underwater and were gifted with a dramatic display of something that looks like green fairy dust from Tinkerbell. This came from much smaller (microscopic) animals, a type of plankton, called Dinoflagellates. Dinoflagellates are found around the whole world and mostly seen around the new moon phase.

After the Dinoflagellates showed up,  we slowly saw more and more tiny dots lighting up in the reef, for just a split second. After a few more minutes the dots became strings. The single Ostracods were swimming in a vertical line towards the surface while flashing and signaling the females. The line of bioluminescence was about 50 cm long sometimes and stayed visible for a few seconds. Nature can be just astounding!  The closer we got to the soft coral, the more we saw, surrounding us – it was truly magical and a bit romantic.  Maybe because Matt was holding my hand, but also because we knew we were enjoying a once in a lifetime experience.

We did not bring the GoPro down as we don’t have the proper equipment to shoot at night below the water, but thanks to Google you can find plenty of images online (see below).  Famed photographer Elliot Lowndes who filmef this National Geographic documentary, you can see a different species lighting up the nighttime Caribbean.  This is ont the same species who were in Bonaire, but it gives you an idea of what it is like during this mating ritual.  Check out this video, especially :30-:53 for highlights

Above the water, you get a beautiful show as well – we did NOT see anything this spectacular, but we did see vibrant green ostracods floating on the surface of the sea.

Diving Bonaire

With the purchase of our new dive gear, Matt and I set out to explore as many dive spots as we could on Bonaire – as it is the dive capital of the world!  Listed below are some of the sites we visited -keep in mind that I am a relatively new diver so what I think is cool and exciting might be “routine” for the more experienced diver.

There are over 80 dive sites on Bonaire and Klein Bonaire so you could do a dive a day for nearly 3 months.  This is a good site – Info Bonaire – dive map

  • Back of boat – Matt and I explored the wall beneath our boat seven times, sometimes to burn through the last remaining bits of our air and other times enjoying longer dives. We started out doing the giant step off the sugar scoops but I found it was much easier for Matt to dump the gear in the water and put it on while it floated.  We always saw something new when we explored this site.

  • “Something Special” – Just before the entrance to the marina, and a short dinghy ride from our mooring, is a dive site called “Something Special” which has extremely diverse flora and fauna.  There are not many corals at this site, but the sandy bottom is a great pace to see rays and turtles.  We did see a spotted eagle ray, turtles, and several other beautiful sea creatures.  We dove this site twice as it was convenient and a great dive.  Here is a great shot of a flounder trying to hide from us.

I cannot remember where Matt shot this video of a flounder running from him – but it is share worthy.

  • “Just a Nice Dive” is located off Klein Bonaire.  Erik, Kyle and Max from Ad Astra joined Matt and I for a 60’ dive.  We swam up current first as it was pretty darn strong, and when we were about half way through our tank we turned around.  The current was so strong that it took us less than 1/3 the time to get back and as we popped up hoping to find our dinghies close by we realized we over shot it by a 1/4 mile.  We attempted to swim back on the surface, but realized we were not moving forward, but rather backward.  After what seemed like forever, we accepted that this route was not going to work, so Matt and I swam toward shore.  Kyle and Max followed as Erik tried to power through.  Unfortunately, he ended up about a mile back.  Matt took off his gear, handed it to me, and swam along the coast in about 18” of water. He passed our dinghies and kept going to the tip of the island and was then able to swim/drift back with the current to the dinghies.  He went after Erik first as he was the furthest away and out of air, then rescued me and the kids.  It was a pretty dive despite the current.
  • “Small Wall” – Our friends, Mizzy and Brian from Kokopeli joined us for a dive at Small Wall which is north of the mooring area. This dive has a stunning vertical wall of corals beginning at 7 meters that deceptively entice you down to about 25 meters.  I would have thought that this would have made me nervous with the wall on one side and the bottom and surface 25 meters away from each other, but it was lovely.  I truly enjoyed seeing all the coral embedded and thriving on the wall – what a totally unique and different experience.  Loved it.
  • “Andrea II” – This site is known for its large variety of sea anemones, hard and soft corals. You will easily spot Grooved Brain Coral, Corky Sea Fingers, and Staghorn.  A remarkable number of large female Queen Parrot fish  (each kind: blue, midnight, and rainbow over 1 meter in length) and can be seen throughout this site.  It was a stunning dive site with a large variety of fish and coral. Kokopeli joined us for this dive.
  • “Mi Dushi” (Klein Bonaire) – Our day out with Ad Astra, Always Sunday, Manado, Kattimi, Cape Grace, Kokopeli.  Mi Dushi is a reef dive with lots of different corals including elkhorn, staghorn, ad gorgonians, sea anemones, and lots of fish.  There were so many of us diving that the allure was a little lost, but this was a very pretty dive site. See blog post “A Day out with Ad Astra”
  • “Karpata” The 2nd dive, on a day out with Ad Astra, was at Karpata.  Good visibility, panoramic view, over branching colonies of elk horn which can stretch from 3 meters up to the top of the surface.  This site freaked me out a little bit as the wall was enormous and curved or was in the shape of a side ways wave.  Meaning there were caverns that you could swim in and out of – the problem was that each cavern had no end in sight – you could not see the bottom – it was a vast empty hole below and that completely WIGS me out.  See blog post “A Day out with Ad Astra”
  • ”Vista Blue” Shore dive with amazing topography of soft corals and sponges along the top reef with schools of goatfish, wrasses, blue chromis and a pretty large green moray eel! See blog post “Sea Donkey Takes us to Vista Blue”
  • “Bachelor’s Beach” –We arrived by dinghy which provided an easy entry and descent. A fairly shallow dive that maxes out at 30 meters.  Lots of hard coral and sea life but not many pockets of sand which makes it harder to see the beauty under the sea. Many fish including reef fish, trumpet fish, file fish, trunk fish, and wrasses.  Kokopeli joined us for this dive.
  • “Eighteen Palms” –This is the first site as you travel south where the reef separates into a “double-reef”. Large tarpon and schools of fish like to swim and play between the two reefs.  I really enjoyed this dive as the fish were exceptionally active, the corals seemed more colorful and the water was crystal clear. Kokopeli joined us for this dive.
  • “Night Dive” – Ad Astra invited Cape Grace, Always Sunday, Manado and us for a night dive. It was my first night dive and I was very nervous.  We jumped in the water right at sunset so that there was still light in the sky.  We headed to the front of the boat to check out the eel between his mooring and to get comfortable in the water as the sky turned dark.  Everyone was outfitted with flashlights so it helped me keep an eye on where everyone was at all times.  We soon headed to the wall and slowly descended down until we hovered at 16-18 meters.  I had hoped to see iridescent corals and fish but it was probably too early in the evening (even though it was pitch black out).  We did get to see all the night fish and sea creatures come out (that usually hide during the day), spotted several eels, some brittle stars and other fascinating creatures.  But, truth be told, I much prefer to dive during the day.
  • “Hilma Hooker” is a wreck dive located on the southern side of the island and is the only dive site with multiple buoys . I will dedicate an entire blog to this dive as it is really interesting.  We dove this site twice and the first time it was pretty clear, but the second dive was later in the afternoon and with a setting sun it made it little merky – but over all a super cool dive.  The stern of the wreck is 21 meters (69′) and the bow is 26 meters (85′) which made this my deepest dive yet at 95′ (stay tuned for this blog). Dove with Ad Astra
  • “The Invisibles” is a double reef system and is located on the southernmost tip of the island.  With gorgeous soft corals especially Sea Plumes and Corky Sea Fingers.   This was one of my favorite dives!  The first reef runs parallel to the shore and a sandy channel cuts through it. The first reef is beautifully overgrown with soft coral that gently dance with the current, it is magical.  An enormous school of Boga were spotted here along with lots of Butterfly fish, Angelfish, and Trunk fish.
  • “Sharon’s Serenity” we dove this site during the day first to get the “lay of the land” before our night dive.  We came to this spot to see the beautiful Ostrocod sexy dance (which is described in detail in a separate post).

I asked several people where there favorite dive spot is and came up with a list of dive sites to explore next time we visit Bonaire.

  • Wayaka II (new post w/ details)
  • Alice in Wonderland (new post w/ details)
  • Salt Pier
  • Tori’s
  • Joanne’s Sunshi (Klein Bonaire)
  • Angel City (two reefs)
  • Cliff
  • Oil Slick
  • 1000 Steps

BON BINI BONAIRE – Hello Bonaire

It’s wonderful being back in Bonaire again as it is so amazing to be able to jump off the back of your boat into your very own aqua blue aquarium filled with coral, fish, and amazing sea life.  Bonaire’s reefs team with various sea creatures such as seahorses, banded coral shrimps and sea cucumbers as well as tons of reef fish including parrot fish, angelfish, and puffer fish.  In addition, three of the world’s endangered marine turtles can be found in Bonaire’s waters: Green turtle, Hawksbill turtle, and the Loggerhead turtle.  We continue to keep our eye out for these rare sightings.

During our first few diving expeditions, right off the boat in 3-6 meters of water, we discovered a moray eel, three huge porcupine puffers, several giant parrot fish, powder blue tangs, angel fish and oh so much more!

The Ramsar Convention is an international treaty that protects the wetlands of great global importance, with emphasis on the significance of waterfowl.  In Bonaire, there are five Ramsar protected sites which tells you just how important their waters are to the locals and the world.

The terrain on Bonaire is managed by the marine parks and is mostly flat with scant vegetation, tons of cacti and salt.  You will find the Caribbean Flamingo, green iguana’s (which are born green and gradually fade in color as they age), and Bonaire Anole’s which live in the trees and camouflage easily into the brown branches.

Bonaire has a population of about 19,000 inhabitants which is a 20% increase from 2011. This 112-square mile island has been seized and ruled by the Spanish, Dutch, and English several times.  The Spanish were the first settlers, but they didn’t care for Bonaire, Aruba, or Curacao and deemed all to be “Islas Inutilas” or Useless Islands.  However, they used the natives as slaves to raise goats, sheep, pigs, and donkeys.

In 1636 the Dutch conquered Aruba, Bonaire, and Curacao and found great use for the islands by mining the salt flats. Over the course of the next several centuries, the Spanish, English, and French tried to fain control over the island.  But the Dutch fought to defend and maintain control.

There is a lot of history crammed into this little island which can be found at the Terramar Museum and other local museums.

We look forward to sharing our experiences as we discover more about Bonaire.
