Marine Life and Jellyfish Exploration

Study Notes

Jellyfish are often perceived as shapeless and disgusting creatures, but underwater, they transform into graceful beings with clever skills to protect themselves, including dangerous weapons.
The box jellyfish and the Portuguese man-of-war are among the most dangerous jellyfish species.
Medusa is a more appropriate term for jellyfish, evoking a sense of mysterious and dangerous beauty.
Medusa's have been evolving for 500 million years, developing fascinating shapes and lifestyles, living in both deep sea and coastal waters like the Baltic Sea.
The life cycle of Medusa's involves a shift between sessile and free-swimming states, with separate males and females reproducing unique young that go through various stages before becoming large Medusa's.
Medusa's have sensory organs for seeing, tasting, and controlling their position in water, consisting of 98% water and can live from 1 to 30 years depending on the species.
Basking sharks feed on jellyfish like Aurelia, with the lion's mane Medusa being a potential prey. The crowned Medusa is considered one of the most beautiful jellyfish species.- Marine researchers work around the clock due to the high cost of marine research.
An ROV went to 300 meters during a marine research expedition.
The team was excited to discover living specimens during their expedition.
A mass invasion of certain fjords by 12 different life Perri filament users remains unexplained.
Each member of the international crew onboard wants a specimen for their own research.
A crab was observed eating the gelatinous outer skin of a Medusa, causing it to dissolve rapidly.
The Azores, a volcanic archipelago in the Atlantic Ocean, is teeming with marine mammals and large fish due to the warm waters from the Gulf Stream.
Pico, an island in the Azores, attracts 24 different whale species between March and April.
Various marine creatures like sunfish, whale sharks, and mobula mantas thrive in the waters off the coast of Pico.
The text explores marine life in various locations worldwide, including Canada, Indonesia, and Australia.
Researchers in Australia study the highly venomous box jellyfish and its life cycle, behavior, and impact on swimmers.- Research vessel c-word Johnson is anchored off Cape Hatteras in North Carolina to search for deep-sea jellyfish as the Gulf Stream heads towards Europe.
The Johnson Sea Link submarine can dive down to 1200 meters, revealing various deep-sea creatures like comb jellies with bioluminescence.
Deep-sea creatures in the Gulf Stream exhibit bioluminescence as a form of communication, prey attraction, and identification of species.
The deep-sea environment features animals like viperfish that can produce up to 1500 biological light bulbs for various purposes.
The exploration also encounters deep-sea squids and octopuses with unique defense mechanisms and adaptations for survival in the dark depths.
