Intro: Documentaries about Bears
Jellyfish (the name applied to medusae) may be some of the oldest creatures on Earth, but they are still mysterious and fascinating to this day. With their graceful, ethereal movements and various colors, jellyfish have been a source of wonder since time immemorial. While these marine animals have captivated the public's imagination for centuries, scientists are still learning more about them every day.
Jellyfish are incredibly diverse in size, shape, color, and behavior, making them one of the most interesting species to study in the natural world. In addition to their beauty and grace, jellyfish play a vital role in the oceanic ecosystem. They are keystone predators that help to regulate the populations of their prey, such as krill and plankton. They also provide valuable food sources for larger species, such as turtles and other fish. With so many fascinating facts about jellyfish, it's no wonder that documentaries have been made about them. From the history of jellyfish to their current environmental impact, these documentaries offer an in-depth look into the lives of jellyfish.
1. Vicious Beauties - The Secret World Of The Jellyfish - Documentaries about Jellyfish
Ready for a thrilling adventure across the globe, delving into the mysterious and fascinating world of jellyfish? Renowned scientist Gerhard Jarms, from the Zoological Institute of the University of Hamburg, takes us on an intriguing exploration. No ordinary journey, this is a voyage to encounter some of the most captivating and venomous creatures beneath our ocean’s surface - medusae.
Beginning in the icy waters of the northern Atlantic, we meet our first enigmatic specimen: the elusive periphylla. With a habitat reaching as deep as 8300 meters, these jellies are not just extreme divers but also vital cogs in our oceans’ machinery. Without them, large migrations of fish and mammals would come to a standstill and disrupt nature’s balance.
Next stop: The Azores! In these rugged Atlantic waters, we scout for shelter-seeking XY jellies who use cave systems as haven during turbulent seas. We then venture far east to Jellyfish Lake in the Pacific, where we’ll have an opportunity to swim among these ethereal creatures. Imagine threading water while being surrounded by countless pulsating forms!
Our expedition doesn’t end there: Western Papua awaits with its stunning coral reefs that rival any artist’s palette with their vibrant colors. Finally, we turn towards Australia’s coast - a place where beauty meets danger. Here lies one of nature’s most paradoxical creations – the fatal sea wasp. A creature so mesmerizingly delicate, yet it holds a deadly secret as one of the ocean’s most poisonous inhabitants.
So buckle up, fellow adventurers! Our journey across earth’s underwater universe promises wonderment at every turn.
2. Jellyfish predated dinosaurs. How have they survived so long? - Jellyfish Documentary
For over 500 million years, jellyfish have flourished in the depths of our ocean, possessing extraordinary genetic capabilities that enable them to exploit their environment like no other species. From those upwards of 30 feet long down to almost microscopic creatures, these unassuming wonders are behind some of the most remarkable advances in biology. Even more intriguing is their formidable toxin, a weapon of immense potency that this ancient species has evolved to ensure its survival.
Follow marine biologist David Gruber as he undertakes an intrepid journey to unlock the hidden powers of jellyfish, and gain unique insights into a species that remains largely misunderstood.
3. The Incredible Way This Jellyfish Goes Back in Time - Documentaries about Jellyfish
In the late 1980s, two lab students accidentally discovered a special jellyfish species called Turritopsis dohrnii. This jellyfish can become young again by going back to an earlier stage of its life cycle, similar to “Benjamin Button”. It was a remarkable finding because it means that the jellyfish is immortal.
Turritopsis dohrnii spends most of its life as a hydroid. Its life cycle begins when adult jellyfish release eggs and sperm. The most mature clone transforms into a smaller version called an ephyra. If this small jellyfish experiences stress or damage, it can revert all its cells back to a younger state. It becomes a cyst and settles on surfaces like the ocean floor.
The immortal jellyfish achieves rejuvenation through cellular transdifferentiation, where one type of cell directly transforms into another without an intermediate form. Specifically, cells on the top layer of the jellyfish’s dome shape and canal system can undergo this change. Through transdifferentiation, specialized medusa cells can become polyp cells. Unlike other animals that have irreversible sexual maturation, Turritopsis dohrnii can reverse its cells at any point in its life cycle.
4. Jellyfish 101 | Nat Geo Wild - Jellyfish Documentary
It is time to unlock the secrets of the jellyfish kingdom. With its perplexing ancestry and remarkable qualities, these soft-bodied organisms proudly display an astonishing variety of forms and functions. From tiny and translucent to large and luminescent, explore the splendid diversity of jellyfish—from their curious anatomy and physiology to their captivating behaviors—and marvel at the brilliance of this complex creature with no brain.
5. Lion's Mane Jellyfish: The Biggest Jellyfish In The World
Marvel at the formidable Lion's Mane Jellyfish, the largest of its kind in the world. This immensely diverse collection of species can be found across all oceans - but none are quite so captivating as the Lion's Mane Jellyfish (Cyanea capillata). Originally discovered off the coast of Massachusetts in 1870 by startled fishermen, who were awed by its gargantuan dimensions of 121.4 feet, the creature was dubbed a 'marine monster'. Truly remarkable, this apex predator stands out from the rest with its impressive size and beauty.
6. Relax for 10 minutes watching jellyfish swimming in Borneo - BBC - Jellyfish Documentary
On the grand stage of Southeast Asia, Borneo stands tall amidst its peers; a verdant utopia that boasts a plethora of life unlike any other island on Earth. Spanning an impressive area twice the size of the British Isles, the third-largest island offers boundless opportunities to explore diverse ecologies—from bustling coral reefs and lush jungles' oasis, to towering mountains, and more. Such varied terrain is home to over sixty-thousand species of plants and creatures, some of which only exist in this tropical paradise.
As if that were not enough, Borneo's coastline is blanketed by some of the most vibrant and biodiverse coral reefs in the world. Incredibly, even a single reef can host more varieties of marine life than the Caribbean Sea! To top it off, one of Borneo's lakes provides a feeding ground for an unprecedented million jellyfish -that have adapted to photosynthesize using algae, granting them a reliable and seemingly infinite food source.
