I think a good approach that uses the exclusion of taxa as mentioned by @thebeachcomber would be:

~ Go to Your observations and use the Project filter with the [**Worldwide Marine Life**](https://www.inaturalist.org/projects/worldwide-marine-life) project (one caveat is that it will only show Research grade observations, but you can use the [**Worldwide Marine Lifee Needs ID**](https://www.inaturalist.org/projects/worldwide-marine-life-needs-id) one for the rest)

~ Then you can exclude fish (Actinopterygii = 47178) or vertebrates (Vertebrata = 355675), adding their corresponding taxon IDs to the URL using **&withouth\_taxon\_id=** (or &withouth\_taxon\_ids= for two or more taxa).

Here, I looked up all of my obs that meet the requirements of the Worldwide Marine Life project and excluded the Actinopterygii.  
(You can use the link and just change the user\_id by your username: [https://www.inaturalist.org/observations?project\_id=worldwide-marine-life&user\_id=roysh&verifiable=any&without\_taxon\_id=47178](https://www.inaturalist.org/observations?project_id=worldwide-marine-life&user_id=roysh&verifiable=any&without_taxon_id=47178))

You can look up the IDs by searching the group(s) you want to exclude with the Search bar; it will be in the URL.
