A mesmerizing aerial video has captured a huge swarm of jellyfish off the coast of Israel. The country’s marine authorities inspected the waters of Haifa Bay during the annual jellyfish migration last month when the boat was surrounded by the mass of tentacled creatures, the Times of Israel reported.
The video shared by the National Parks and Wildlife Authority shows the giant swarm of jellyfish making the water look speckled white from above.
Watch the video below:
The Parks and Nature Authority said pollution and climate change are increasing the intensity of the jellyfish swarms. In a press release, the officials said the many things people are doing help spread jellyfish, including digging the Suez Canal, polluting the sea with sewage, climate change and harming jellyfish predators such as angelfish and sea turtles.

According to the Times of Israel, most jellyfish that visit Israel are migratory, invasive species. They originate from the Indian Ocean and are said to reach the eastern Mediterranean via the Suez Canal. The tentacled creatures pose a threat to Israel’s power supply as they are sucked into the country’s power plant, which uses seawater for cooling.
Jellyfish were among the first inhabitants of the planet. Today they live in all the seas and oceans of the world at every depth. The invertebrates have no brains and consist of 95-98% water. Their tentacles can sting and inject venom into humans, usually resulting in mild to severe discomfort. In some rare cases, their sting can also lead to extreme pain or even death.
