NOSTALGIA: A look at Cumbria's love of the sea on World Jellyfish Day
For this Nostalgia edition, we take a look at World Jellyfish Day, celebrated on November 3.
The jellyfish, an invertebrate that has been on Earth for millions of years, isn't actually a fish because it doesn't have a spine.
- Jellyfish don't have gills, a brain, heart, bones, or blood.
- They are made up of 95 percent water and have skin through which they absorb oxygen.
- Their body is called a bell, and they swim by contracting and relaxing the muscles around it.
- Their tentacles contain stingers that protect them from prey.
Photos show how people in Cumbria have shown their fascination for aquatic life.
