I'm an aspiring marine ecologist from Southern California with a specialty in identifying cnidarians and echinoderms, as well as a little bit of knowledge regarding Hawaiian reef fish. My main passion is the community ecology of reef organisms, especially the specific strategies used by individual species to secure an advantage over others. Here's a list of some guides that I've created or helped create...

- Echinoderms of the North Eastern Pacific (
- Cnidarians of the North Eastern Pacific - Anthozoans (
- Cnidarians of the Eastern Pacific - Pelagics (
- Chaetodontid Identification - (

***Hawaiian Reef Fish Guide is currently under revision. I plan to have it back up in a week or two.

Feel free to tag me in observations that you would like me to take a look at

More guides and plenty of IDs coming your way very soon!
