Many people are stung by Lion's mane jellyfish during the summer, but encounters with this jellyfish in Norway are usually more unpleasant than dangerous.
The Lion's mane jellyfish contains a venom which consists of a mixture of substances. The venom is released from cells in the tentacles when they are stimulated either mechanically or chemically.
Symptoms of jellyfish stings in Norway can include:
Other signs such as nausea, muscle pain, breathlessness, allergic or hypersensitivity reactions may occur, but are rarer.
In the event of injury to the eyes, severe pain can develop rapidly. Such injuries will require medical attention more often than injuries to the skin.
Many different species of jellyfish live in warmer waters which can cause severe symptoms after stinging. Life-threatening reactions can occur in the worst case scenario.
To avoid unpleasant encounters with the poisonous creatures of the sea, it is important to follow the advice of the local authorities when swimming.
