I would like to know if sea slugs lay eggs

Dear Emily,
The short answer is yes, sea slugs do lay eggs. They usually lay them in a long string, like a string of beads, which is coiled up in a jelly mass to protect the eggs from predators and bacteria. Many species have very elaborate egg ribbons, and often you can identify the slug that laid the egg ribbon just from its shape.

There is a lot of information and photos of eggs on the Forum in the Fact Sheets, and the many messages. The best way to find it is go to the SEARCH PAGE and type in egg. You will get a list of over 400 photos and messages to have a look at. If you are interested in other general information click on the GENERAL TOPICS Button at the top of the page and you will get an index of topics which may be of interest.

Best wishes,
Bill Rudman
