Our group of Mt Modonna Students were thrilled to learn about the California Sea Hare during our kayaking field trip to Elkhorn Slough. Sea hares, a large marine slug can emit a midly toxic purple dye as a defense. Slow moving grazers, they are simultaneous hermaphrodites and are sometimes found in large mating masses known as daisy chains or roman circles


We also found the gelantious Ctenphore or comb jelly which empowers sicky cells rather than  stinging cells like the true sea jellies (cnidarians) employ. IMG_0692

Mt Modonna’s Pal program matches a senior as a role model with a 3rd grader during adventures throughout the school year. Super cool and highly effective concept.

Teachers, join us on a naturalist-led field trip with bluewaterventures.org. We love our outdoor classroom!



Imagine a jellied filled sac, a simple life form that saw the Dinosaurs come and go, flourishing on earth for over 300 million years. You have no brain nor heart or even a proper anus. You have just consumed the soft juicy tissues of a California mussel, dislodged from the grasps of its stringy cementing agent by a powerful wave. The calcareous mussel shell pops out of your mouth that serves as both the beginning and end of your digestive tract.

Sea anemones, though a mere bundle of jelly, are formidable predators. They are armored with 1000’s of stinging cells known as nematocyst that capture their prey. The aggregating anemone pictured here can produce sexually through the dispersal of egg and sperm or asexually by cloning. Essentially, they pull themselves apart creating a genetic clone over and over again until they blanket their rocky condo. Specialized warrior polyps on the edges of the colony inflate with powerful nematocyst cells that will attack neighboring colonies. In some cases a neutral zone between colonies will be established where each colony is spared the lethal reach of the other.



While surf fishing today, we were distracted by the tide pools. Leptaasterias hexactis, known also as the Six Rayed or Brooding Sea Star only reaches a size of slightly more than 3 inches. This particular star pictured has lost a leg to an intertidal predator. While many sea stars reproduce by broadcasting their egg and sperm into the water column, these little stars are attentive mothers. Females will stand guard over a mass of yellow eggs and then guard her young stars until they are foraging on their own.Tasty mollusks such as the Lined Chiton are considered a delicacy by these tiny echinoderms. The brooding process may take several months all while the female is fasting.

Elkhorn Slough offers an incredible location to kayak among sea otters, harbor seals sea lions and an array of migratory birds. We encourage teachers to get your students on a naturalist-led field trip to Elkhorn Slough.

We offer a unique program that includes activities both in the water and on land to reinforce our outdoor curriculum. Most outfitters only spend a few hours on the water. We feel we offer something special.

Our Elkhorn Slough program includes: wetlands ecology, endangered species, natural history of sea otters, harbor seals, sea birds and cultural history. Leadership and teamwork are key components of your field trip.

After lunch, we pull a large seine net to examine our catch and discuss the theme of animal adaptations further.

We offer a leisurely paced, full day in Elkhorn Slough from 9:30-2:00 for only $38 per person. This includes time on the beach for lunch and activities.

And remember….Adventures are for Life!

It started with an excited cry from Biology Teacher, Jane Orbuch ” Kim, there’s a whale”. I had just led 14 San Lornezo Valley High School students by kayak to the kelp beds edging a surf break known as Indicators in Santa Cruz. We were just about to begin a lesson in Kelp Forest Ecology. Slipping off of their sit on top style boats and into the invigorating 55 degree water, the students were anticipating an eye level encounter with sea otters, harbor seals, top snails and other wonders of this remarkable marine ecosystem. Humpback Whales were not in the lesson plan.

Monterey Bay National Marine Sanctuary has recently been coined the "Serengeti of the Sea". The Sanctuary lies within a biologically rich pathway intersecting the migration patterns of an array of marine mammals, sea birds and even our planet's most elusive and largest sea turtle, the Leatherback. 26 species of marine mammals are found in Monterey Bay National Marine Sanctuary, the largest federally protected marine reserve in the United States.

Jane's discovery was the beginning of one of the most unique 12 days of wildlife observation in my 27 years as a naturalist. Humpback whales, weighing 80-90,000 pounds and reaching a length of 50 feet rarely meander close to our shore where water depths average 30-40 feet. Their visits to shallow water are more typically ethereal, making an appearance for a few hours or a day. Humpbacks are filter feeding whales that use their fringed plates of baleen to sort out krill, a small crustacean that congregate over the plankton rich Monterey Bay Canyon. Humpbacks are known to switch their food selection to larger bait fish such as anchovies and sardines when the situation presents itself. Our visiting whales developed quite a taste for anchovies that were schooling close to shore. The magical 12 day journey had begun.

As the students slowly paddled offshore, I glanced at my fore arm and noticed that every hair stood erect. I was virtually speechless, a condition that my students have rarely witnessed over the years of my interpreting ocean wonders. The four instructors managed to share a few Cetacean facts and viewing etiquette. In truth, it was an extraordinary educational moment that required no words. The whales were centered stage and the students witnessed an array of behaviors from pectoral fin slapping to the most impressive behavior of all, a breach, when a whale propels its body out of the the water followed by a dramatic plunge downward. Lingering in our memory bank will be the unforgettable scent of anchovy breathe expelled through the blow hole of an exuberant whale. As we paddled back to shore, one student proclaimed: "This had been the best day of my life".

One of the most profound experiences of my life occurred several days later. Launching from the Santa Cruz Wharf, a friend and I made our way by kayak toward an area where we had seen a few spouts. As we neared the vicinity where the whales were last spotted, we stopped paddling and drifted. Without much warning, we found ourselves surrounded by a pod of very energetic sea lions. We observed them quickly alter their course and leap out of the water, a behavior known as " porpoising" which occurs when seals pursue prey or are being pursued by a predator such as a White Shark or Orca. The prey, in this case were anchovies feeding on a rich soup of plankton.

As the sea lions rocketed towards us, our immediate instinct was to back paddle. We started tapping our plastic vessel letting any stealthy 50 ton visitor know our location. Then one of the most incredible moments of my twenty seven year career as a naturalist occurred. As we drifted and tapped, a humpback whale gently raised its head out of the water approximately five feet from us. This astounding behavior is known as "spy hopping", when a whale approaches an object such as a boat to take a better look. The whale's eye will either be slightly above water or just below as the whale glances upward through the water column. We were being checked out by a 90,000 pound creature.

As quietly as it had arrived, the whale sunk back below the blue hued sea. I struggle to find the words to express the feeling that flooded through every pore of my body. We were in awe and overloaded by the adrenaline that pulsated through us.

Several days later on a Sunday, I led my one and only commercial trip to experience the whale phenomena that was occurring in Santa Cruz through my business, Blue Water Ventures. Before launching, I instructed my group of kayakers on proper whale etiquette and informed them that they would be escorted back to shore if instructions were not followed.

The image as we departed Santa Cruz Harbor will stay with me for years to come. The interest in viewing had exploded since earlier that week when there were just three of us and the whales. It was a view of ecotourism gone astray and we were contributing to it. Federal law requires us to stay 100 yards away, the length of a football field, from any marine mammal. Just leaving the harbor brought us too close as we soon discovered that the whales were positioned just outside Santa Cruz Harbor. The horizon was hauntingly still, though noisy with the image of human bodies standing upright on boards, kayakers, boogie boarders, surfers, sail boats and motorized skiffs. Moments later a helicopter circled above. Unbelievably whale watching by helicopter had arrived on the scene. Though thrilled to share the whale experience with my respectful group of women, I was eager to get them safely back to shore and give the whales the space they required to feed. We saw very little spy hopping that day. Humans floating on some form of plastic or fiberglass vessel were no longer a novelty and perhaps more of a nuisance. I soon cancelled my upcoming plans to kayak with the whales and turned inquiring customers away.

My hope was that the whales were well fed, fat, happy and on their way to tropical seas. Forty eight hours later, the anchovies were gone and so were the whales.

Looking for a really unique experience for your students? During our adventurous field trip, we’ll slide off our sit on top kayaks to have an eye level experience with Monterey Bay National Marine Sanctuary! Using goggles or a mask/snorkel, take a look at the kelp forest or choose to remain dry and simply glide over the forest canopy searching for sea otters, harbor seals, sea lions and sea birds. Encompassing 5,322 square miles of ocean, our remarkable sanctuary supports one of the planet’s most biologically diverse marine ecosystems. The use of sit on top kayaks with the option to submerge into the water gives us an entirely different perspective on our ocean world.

This is a great fall field trip! In the spring, we’ll launch our closed deck boats searching the water for migrating California Gray Whales with their plump babies in tow.

During our naturalist-led kayaking tours in Elkhorn Slough we see the most amazing behaviors. White Pelicans, with a wing span of 9 feet are featured here foraging in the wetlands. Unlike the Western Brown Pelicans that plunged from the sky when feeding, White Pelicans scoop food without diving. They are known to work together to heard fish by forming a net with their collective bodies. Join us for an unforgettable day kayaking in Elkhorn Slough!

The key to successful kayak rescues for 8-10 year olds is making it FUN and having them feel comfortable with their gear…..jump on!
