Song of a Humpback Whale

http://www.bluewaterventures.org

Dipping into what seems like a deep blue silence, I am greeted by the erie song of a humpback whale in the vast south pacific ocean surrounding Tonga. If you are near a singing whale, the sound comes from within as it pulsates through your fluid watery body. The tones literally flows through you and you can feel it reverberating through your core. Some people describe a sensation in their chest or felt in their bones. Off the islands of Vava’u I felt it seeping through my body, pulsating and tingling. I dove deep into the blue abyss alone but not, listening and in awe.OLYMPUS DIGITAL CAMERA

Only the male humpback whales sing an elaborate song and primarily during the breeding and calving season. While much is still unknown, its thought that air is pumped through sacs attached to the larynx region and then reverberates out through their massive throat. It is truly one of the greatest concerts on earth which was shared among an intrepid crew with www.bluewaterventures.org! Thank you whales…..

We were simply spellbound watching a reef squid feeding at night on our recent BVI Multi Sport Sailing Adventure! The video captures the pulsating chromatophore color cells and the lighter feeding tentacles waiting to strike. It happened so quickly that we missed capturing it on the video, but we’ will all remember the rapid strike and entanglement of a tiny fry fish, possibly a silverside.

The next morning, several of us encountered a school of over 60 reef squid watching us as we watched them! So many great moments in the Caribbean! Join us at www.bluewaterventures.org.

Encounter with a Humpback Whale

The California population of humpback whales may exceed 50 feet in length and weigh over 80,000 pounds. When food is available, they may consume over 4000 pounds daily trapping their prey in fringed baleen plates that hang from their upper jaw. Humpback whales that give birth in the South Pacific region of Tonga feed in the rich Antarctica polar region and may weigh as much as 50 tons or 100,000 pounds.
Dipping into the indigo blue deep water around the islands of Tonga, it was somewhat difficult to grasp how big these incredible mammals were. Snorkeling next to them it was clear you were with one of the biggest animals on earth but size was harder to determine against the deep blue background. However, during one memorable swim a mother humpback whale glided below us to escort her calf away from the potentially dangerous shallow reef that the young whale was heading for. As the mature female whale cruised below us we could see how massive she was against the shallow reef. It was truly one of those moments of awe and wonder watching a graceful, gentle and gigantic creature care for its young calf.

The Best of Baja

http://www.bluewaterventures.org

Every february Blue Water Ventures travels to the whale breeding lagoons of Baja and the Sea of Cortez teaming up with our incredible local outfitter, Mar Y Aventuras. For 10 action packed days, we snorkel with sea lions, observe reef fish, sea kayak, beachcomb and hope for a ‘friendly” encounter with the California gray whales of Magdalena Bay.

Baja Highlights
* Kayaking through mangroves and from our secluded base camp of Espiritu Santo Island in the Sea of Cortez

* Unforgettable Encounters with Cailfornia Gray Whales, Magdalena Bay on Baja’s Pacific Coast

* Snorkeling with Sea Lions and Colorful Reef Fish in the blue waters of Baja

* Beach combing for treasures along beautiful deserted beaches

* Delicious local seafood caught and prepared by our Mexican Crew

* Skiff supported base camps with spacious tents

* Naturalist-led hikes, snorkeling excursions and whale encounters

* Sunrises and Sunsets over magnificent desert scenery

*Swimming alongside a filter feeding harmless shark that may be over 30 feet in length

Each year during our Caribbean programs in Belize and the British Virgin Islands,  our group is invariably drawn to the Caribbean Reef Squid, Sepioteuthis sepioidea. Even seasoned snorkelers become overwhelmed by the explosion of colorful activity found on a coral reef. Suspended in blue water, an erie feeling that something is watching you creeps into your consciousness. A quick glance around reveals a squadron of reef squid. Swim away and they follow. Move towards them and they quickly change color, a deep red if near the reef or pale if over sand, masters of camouflage.

They may even create false eyes on their posterior end as seen here. The eyes will instantaneously vanish once the threat of a predator is gone. Quite incredible.

 

The  picture  below reveals an unusual white blotch across the dorsal side. I have watched reef squid for decades and have rarely seen such coloration. It appears as though we may have interrupted the amorous intentions of a courting male.

Reef squid not only expand and contract the chromatophore cells embedded in their skin to conceal themselves, but do so as part of their mating ritual. Males may flash an impressive zebra pattern to the female who is revealing a blotchy saddle indicating her sexual receptivity. Mate selection is a serious business to a female reef squid. She will die soon after depositing her fertilized eggs in a safe corner of the ocean floor. Like most cephalopods, the life of the Caribbean Reef Squid is relatively short. They are thought to live for one year, mate and die.

Over 25 years ago I saw my first manatee mating event. I was leading a program for the Smithsonian Institute and I will never forget it. Since then, I have snorkeled among an esterous herd, a rambunctious gathering of amorous males in pursuit of a receptive female.  Rarely have I witnessed  the  actual attempt to impregnate  the female. While female manatees reach sexual maturity at 5 years of age, male manatees are later bloomers. Typically they are sexually mature by 8 or 9 years of age though sometimes earlier. This young male who we have named Romeo certainly gave it a go but O2 or lack of it got in the way.

OLYMPUS DIGITAL CAMERANote in all 3 videos clips, the smaller male surfaces for air and then must start his amorous intentions over where he left off.  Females are often forced into the shallows by the advances of an esterous herd and will be mated by multiple males. We witnessed such an event in another area of the river.

Perhaps this female realized that Romeo’s  amorous  pursuit would be futile or perhaps later in the day he succeeded. Either way, it was an unforgettable and fascinating interaction to observe. We have named the female manatee Cougar…Life as we travel through the south lands with http://www.bluewaterventures.org

During our yearly expedition to the Sea Of  Cortez, we made an incredible discovery. A tiny, barely discernible commensal shrimp was  found living among the tube feet of Bradley’s Sea Star (Mithrodia bradeyi). The sea star shrimp (Periclimenes sorer) was barely visible until we realized it was mimicing the tube feet of the sea star.

Each day we have  new discoveries during our  yearly Baja Adventure to the Sea of Cortez and Magdalena Bay. Our Baja programs are offered each year late January through February.

Today we snorkeled among 100’s of Golden Cow Nose Rays…..simply magnificent!

Capable of detecting the weak bioelectric fields of their prey such as benthic clams, these incredible cartilaginous fish are amazing to observe at such close range.  Related to the majestic spotted eagle rays, the golden cownose  rays  have a defensive spine at the base of their tale.

There are those teachable moments be it in a traditional classroom or in an outdoor setting, that both student and teacher will never forget. On the final day of Coastal Kayak Explorer’s Camp we shared one of those moments.

Each summer Blue Water Ventures  based in Santa Cruz, CA  offers a variety of marine science camps. Kim Powell, owner of Blue Water Ventures leads our summer camps.  Kim has been conducting wilderness expeditions for students since 1985. She is a certified sea kayaking instructor through the American Canoe Association and Wilderness First Responder.  Kim loves sharing her knowledge of the marine world through a fun and informative approach. She has been the Director of Marine Science Camps in several  Caribbean locations in addition to Central California.
