Jellywatch

Explore the mysteries of jellyfish - and help ocean science too!

Have you seen a jellyfish, red tide, squid, octopus, shark or other unusual marine life recently? If so, tell us about it with the Jellywatch app! Marine biologists need your help to develop a better understanding of the ocean. If you’ve been on the beach or in the ocean lately, you can contribute to a long-term dataset by telling us about the animals you saw or the conditions of the beach. You can help us even more by submitting a picture of what you saw!

The JellyWatch project is working with NASA to better understand the effects of toxic algal blooms, also known as 'red tides'. Please submit sightings of red tides and sick or dead marine mammals.
