Ahoy The Living Sailors Volunteers! Our Case Study of The Living Sailor Project is now online, read the paper here 🪼⛵🐦🥤 Thank-you all for studying the strange and beautiful jellies on the sea surface with us!

Help us understand how these living sailors navigate the vast global ocean
Learn moreLook at each subject set and determine if the living sailor(s) have left- or right-facing sail, alive or dead, and count them.

Floating life is a critical component of the ocean surface food web. Knowing how, where, and why this drifting community navigates the vast global ocean is fundamental to understanding the ecology of the ocean surface.
The Living SailorABOUT LIVING SAILORS
Living sailors travel the world's oceans. These beautiful and strange jellies float at the surface and harness the wind with a fleshy sail. Over 60 years ago a Soviet scientist hypothesized that left- and right-facing sails travel across different parts of the ocean. Was he right?
How you can help!
Using community-collected images from around the globe, we will count left and right living sailors to test this half-century-old hypothesis!
Please note:
We rely on images collected by community contributors to the GO-SEA Science project and iNaturalist. Images will include jellyfish, both alive and dead, that have washed ashore around the world.
