SE made an error when they named this family. They clearly based the creature on the sea angels known as clionidae, but rather than properly calling the creature a clione, they named it clionid, which is a name for sponges that are members of the clionidae family of sponges rather than the clionidae family of sea angels.
"Clionids" is an acceptable plural form for the sponges, but not the sea angels.
"Clionidae" is an acceptable plural form for both the sponges after which these creatures are named AND the sea angels on which they are based. Using this rationale, I've selected Clionidae as the middle ground as it's an acceptable plural form in either situation. --Blue Donkey Kong (talk) 02:07, March 2, 2014 (UTC)
