Here are some key characteristics of the Black Sea Nettle:
- Size: The Black Sea Nettle is known for its large size. Its bell can reach a diameter of up to 1 meter (3 feet), making it one of the largest known species of jellyfish.
- Appearance: The bell of the Black Sea Nettle is dark brown to black in color, which gives it its common name. It has long, trailing tentacles that can extend several meters below the bell. The tentacles may also have a dark coloration.
- Sting: The Black Sea Nettle has stinging cells, or nematocysts, on its tentacles that it uses for capturing prey. While its sting is not typically life-threatening to humans, it can cause mild to moderate discomfort, including skin irritation, redness, and a stinging sensation. It is advisable to avoid direct contact with the tentacles to minimize the risk of stings.
- Feeding: Black Sea Nettles are carnivorous and primarily feed on small fish, plankton, and other small marine organisms. They use their tentacles to capture prey, and once captured, they bring the prey close to their mouth for digestion.
- Behavior: Black Sea Nettles are capable of both horizontal and vertical movement in the water. They have a pulsing motion that propels them through the water and helps them capture prey.
The Black Sea Nettle is an impressive jellyfish species due to its large size and distinctive dark coloration. While encounters with this jellyfish are relatively rare, it’s important to exercise caution and maintain a safe distance to minimize the risk of stings.
