WHAT THE HECK IS A SALP?
When we entered the Sea of Cortez, we started seeing lots of sea life. We noticed many small to medium size jellyfish going past the boat as we sailed north.
There was one ocean critter floating near the surface we had never seen previously. That’s saying something because we sailed around the world on Exit Only, and we thought we had seen pretty much everything there was to see floating on the surface of the ocean.
This new animal looked like jelly fish in a chain. And so the debate began.
Was it a jelly fish? Was it the eggs of some pelagic species that was found only in this new area of the world?
I favored jelly fish living in a colony linked together to create a long chain. Some of the chains were more than a meter long.
The definitive answer would not come until a week later when we could go on line and identify the nature of the beast.
It turns out that it is a SALP.
None us had ever heard of Salps, so we did not know that such creatures existed.
It turns out that Salps are very common in certain areas of the world, especially in the Artic regions.
You can read about Salps in wikipedia at the following link: https://en.wikipedia.org/wiki/Salp
A salp (plural salps) or salpa (plural salpae or salpas) is a barrel-shaped, planktic tunicate. It moves by contracting, thereby pumping water through its gelatinous body, one of the most efficient examples of jet propulsion in the animal kingdom. The salp strains the pumped water through its internal feeding filters, feeding on phytoplankton.
Salps are common in equatorial, temperate, and cold seas, where they can be seen at the surface, singly or in long, stringy colonies. The most abundant concentrations of salps are in the Southern Ocean (near Antarctica), where they sometimes form enormous swarms, often in deep water, and are sometimes even more abundant than krill. Since 1910, while krill populations in the Southern Ocean have declined, salp populations appear to be increasing. Salps have been seen in increasing numbers along the coast of Washington.
Salps have a complex life cycle, with an obligatory alternation of generations. Both portions of the life cycle exist together in the seas—they look quite different, but both are mostly transparent, tubular, gelatinous animals that are typically between 1 and 10 cm (0.4 and 3.9 in) tall. The solitary life history phase, also known as an oozooid, is a single, barrel-shaped animal that reproduces asexually by producing a chain of tens to hundreds of individuals, which are released from the parent at a small size.
The chain of salps is the 'aggregate' portion of the life cycle. The aggregate individuals are also known as blastozooids; they remain attached together while swimming and feeding, and each individual grows in size. Each blastozooid in the chain reproduces sexually (the blastozooids are sequential hermaphrodites, first maturing as females, and are fertilized by male gametes produced by older chains), with a growing embryo oozoid attached to the body wall of the parent. The growing oozoids are eventually released from the parent blastozooids, and then continue to feed and grow as the solitary asexual phase, closing the life cycle of salps. The alternation of generations allows for a fast generation time, with both solitary individuals and aggregate chains living and feeding together in the sea. When phytoplankton is abundant, this rapid reproduction leads to fairly short-lived blooms of salps, which eventually filter out most of the phytoplankton. The bloom ends when enough food is no longer available to sustain the enormous population of salps. Occasionally, mushroom corals and those of the genera Heteropsammia are known to feed on salps during blooms.
So there you have it. You now know that Salps exist, and that they are sequential hermaphrodites - whatever that means.
If reincarnation turns out to be true, I don’t want to come back as a salp.
On the other hand, I have the feeling that many Salps have been reincarnated as humans who live and act as if they do not have a brain.
Awesome music video that captures the essence of what it's like to sail offshore in a catamaran around the world when conditions are less than perfect. David Abbott from Too Many Drummers sings the vocals, and he also edited the footage from our Red Sea adventures. This is the theme song from the Red Sea Chronicles.
Sailing up the Red Sea is not for the faint of heart. From the Bab al Mandeb to the Suez Canal, adventures and adversity are in abundance. If you take things too seriously, you just might get the Red Sea Blues.
If you like drum beats, and you like adventure, then have a listen to the Red Sea Chronicles Trailer.
Flying fish assault Exit Only in the middle of the night as we sail through the Arabian Gulf from the Maldives to Oman. And so begins our Red Sea adventures.
Sailing through Pirate Alley between Yemen and Somalia involves calculated risk. It may not be Russian Roulette, but it is a bit of a worry. Follow Team Maxing Out as they navigate through Pirate Alley.
Stopping in Yemen was just what the doctor ordered. We refueled, repaired our alternator, and we made friends with our gracious Yemeni hosts. We also went to Baskins Robbins as a reward for surviving Pirate Alley.
After you survive Pirate Alley, you must sail through the Gate of Sorrows (Bab Al Mandab) at the southern entrance to the Red Sea. The Gate of Sorrows lived up to its name with fifty knots of wind and a sandstorm that pummeled Exit Only for two days. Life is good.
Captain Dave and his family spent eleven years sailing around the world on their Privilege 39 catamaran, Exit Only. During the trip, the crew shot 200 hours of video with professional cameras to show people what it's like to sail on a small boat around the world.
The Red Sea Chronicles is a one hour and twenty-two minute feature film showing their adventures as Exit Only sails through Pirate Alley in the Gulf of Aden and up the Red Sea. The professional footage documents their experiences in Oman, Yemen, Eritrea, Sudan, Egypt, and the Suez Canal. It chronicles the rigors of traveling in a remote section of the world rarely visited by cruisers. Exit Only dodges Yemeni pirates, fights a gale and sand storms in the Bab al Mandeb at the southern entrance to the Red Sea. The crew explores deserted islands on the western shores of the Red Sea, and learns to check the cruising guides for land mines before venturing ashore.
The Red Sea Chronicles also has outstanding Special Features including an Instructional Video on Storm Management that tells sailors how to deal with storms at sea.
The Red Sea Chronicles is a first class adventure that stokes the sailing dreams of both experienced and wannabe sailors alike.

Although I like the feel of a paper book in my hand, I love trees even more. When people purchase an eBook, they actually save trees and save money as well. Ebooks are less expensive and have no negative impact on the environment. All of Dr. Dave's books are available at Save A Tree Bookstore. Visit the bookstore today and start putting good things into your mind. It's easy to fill your mind with positive things using eBooks. No matter where you are or what you are doing, you can pull out your smart phone or tablet and start reading. You can even use electronic highlighters and make annotations in your eBooks just like paper books.
