Nudibranch and Sea Slugs Identification

To make it easy for you in identifying a sea slug or nudibranch and make the best use of Nudi Pixel nudibranch photographs collection, it is recommended to follow these steps:

  1. Go to genus list of nudibranch and sea slugs
  2. Observe each species within that genus
  3. If you can not find any similar species, go to the bottom of the page, and find links to another genus. Click on one of it and again, observe each species within that genus. If after you review all genus list and you still can not find a proper identification, check through unidentified nudibranch list, your species might be one of them.
  4. In many cases, a casual photographer often mistakenly identifying polyclad flatworms as opistobranchs, so check our Polyclad Flatworms Photo Gallery. Furthermore, you can take a look at Nudi Pixel non nudibranch photos where some species often mistakenly thought as a nudibranch such as cowries, ovulids, shells are displayed.
  5. Lastly, if you still can not find it, submit your nudibranch photos with detail information about it, we would be glad to help you identifying it by sending the pictures to some nudibranch experts. Please note that by submitting you also give us the permission to publish your photo in Nudi Pixel (we keep the copyright notice to you, though). And if it doesn't meet our quality, we could NOT identify and publish it.
