Most chromodorid nudibranchs lay a typical dorid egg mass in which one edge of the flattened ribbon is attached to the substrate in a spiral. A few species have been reported to lay an egg mass in which one side of the ribbon is stuck to the substrate. This may be an interesting clue to phylogenetic relations in the family or it may have some function. This page is a place to record any records of this type of egg mass, preferably with photos. See Nerida Wilson's list below.

Listed below are observations on the Forum to photos of this type of egg ribbon with a link to relevant messages.
