Fact Friday

Nudibranchs, or sea slugs, are colorful little sea creatures.  Their name literally means “naked gills” which refers to the feathery respiratory appendage you can see in the middle of this sea slug’s back.  Many species of nudibranch are able to ingest food toxic to most other organisms and incorporate those toxins into their skin.  Their bright colors warn that they are toxic.
