Oceanographers suggest that the appearance of this jellyfish could be due to warming of the ocean or possibly due to
an increase in the populations of plankton which these jellyfish feed upon.
(see the article: "Rare dark jellyfish species showing up in San Diego Bay "
at the website:
"The black sea nettle (Chrysaora achlyos), sometimes informally known as the "black jellyfish"
due to its dark coloration, is a giant jellyfish, with its bell measuring up to 1 m (3 ft) in size, and its
oral arms extending up to 6 m (20 ft) in length.Despite its size and occasional proximity to Pacific
coastal cities, the Black sea nettle was only recognized and scientifically described as a
separate species in 1997, though misidentified pictures of the jellyfish had been taken in 1925.
It has the scientific distinction of being the largest invertebrate discovered in the twentieth century."
According to an article at the following website:
"The black sea nettle, rarely seen along the county coastline,
began its latest surprise visit (in San Diego Bay) a few weeks ago,
when the ocean water topped 70 degrees."
"Mystery surrounds the black sea nettle because it has appeared in local waters
just five times since 1926. The last visit was in 2005.The species typically thrives in

Here is an educational video about these jellyfish which I found at Youtube:
Thank you to Youtube member hdvdiva for allowing me to use this video:
"Jellyfish are viewed as barometers of ocean health and possibly a powerful force
affecting seawater itself.Scientists remain cloudy about the role of jellyfish in the ocean
ecosystem, but the creatures are undeniably hardy. Unlike sharks, orcas and other
aggressive carnivores, jellyfish thrive in ecosystems damaged by human activity.
From the Gulf of Mexico to the Sea of Japan, oceanographers have found a common
symptom among places where overfishing, chemical pollution and rising sea temperatures
have killed off other species: more jellyfish."

Thoughts worth thinking about
Laws alone can not secure freedom of expression; in order that every woman and man present their views without penalty, there must be spirit of tolerance in the entire population.- Albert Einstein Too often we underestimate the power of a touch, a smile, a kind word, a listening ear, an honest compliment, or the smallest act of caring, all of which have the potential to turn a life around. - Leo Buscaglia
A person's true wealth is the good he or she does in the world. - Mohammed
Our task must be to free ourselves... by widening our circle of compassion to embrace all living creatures and the whole of nature and its beauty. -Albert Einstein
The best way to find yourself, is to lose yourself in the service of others. - Ghandi
The unselfish effort to bring cheer to others will be the beginning of a happier life for ourselves. - Helen Keller
Aim for success, not perfection. Never give up your right to be wrong, because then you will lose the ability to learn new things and move forward with your life. Remember that fear always lurks behind perfectionism. Confronting your fears and allowing yourself the right to be human can, paradoxically, make yourself a happier and more productive person. - Dr. David M. Burns
Life is as dear to a mute creature as it is to man. Just as one wants happiness and fears pain, just as one wants to live and not die, so do other creatures. -His Holiness The Dalai Lama
Mankind's true moral test, its fundamental test (which lies deeply buried from view), consists of its attitude towards those who are at its mercy: animals. And in this respect mankind has suffered a fundamental debacle, a debacle so fundamental that all others stem from it. -
Milan Kundera, The Unbearable Lightness of Being
The worst sin towards our fellow creatures is not to hate them, but to be indifferent to them. That's the essence of inhumanity. -George Bernard Shaw
Ego's trick is to make us lose sight of our interdependence. That kind of ego-thought gives us a perfect justification to look out only for ourselves. But that is far from the truth. In reality we all depend on each other and we have to help each other. The husband has to help his wife, the wife has to help the husband, the mother has to help her children, and the children are supposed to help the parents too, whether they want to or not.-Gehlek Rinpoche Source: "The Best Buddhist Writing 2005 pg. 165
The hostile attitude of conquering nature ignores the basic interdependence of all things and events---that the world beyond the skin is actually an extension of our own bodies---and will end in destroying the very environment from which we emerge and upon which our whole life depends.
