Worldwide Jellyfish Watch website

May 30th, 2010 by Richard Lord

The Monterey Bay Aquarium Research Institute (MBARI) has created a jellyfish sighting database on the web.  If you find a jellyfish on a Bailiwick of Guernsey beach or in the sea you can submit the record to the MBARI.  Go to the Create new sighting web page where you will see a map. A red marker will be positioned over Monterey.

This is a screen shot of the map. Go to the website and drag the red marker from California to the Bailiwick of Guernsey to pinpoint the location of the jellyfish sighting

Drag the red marker all the way across the world to the Guernsey location where you saw the jellyfish and fill in the information in the boxes provided.  You do not have to subscribe to the website to fill in the information.  You can zoom in and out of the map.  The zooming feature will allow you to pinpoint the location of your jellyfish sighting in the Bailiwick of Guernsey.

The Jellyfish watch page allows you to upload up an image of the jellyfish you saw (up to 2 mb).

The jellyfish watch website will help oceanographers develop an understanding of jellyfish distribution.

The Guernsey Biological Records Centre also collects information for all species found in the Bailiwick.  Any jellyfish records submitted to the Jellyfish Watch website should also be submitted to the Guernsey Biological Records Centre as well.

If you require help with identification of Guernsey jellyfish please email fishinfo (at) and replace the ‘(at)’ with @
