Curious Microscope Finds

[saltyarmreef]

Hi Everyone! I've been sampling different parts of my newly-cycled aquarium for fun and found some curious creatures. Does anyone have an idea as to what I've found?

1. Located in the sump attached to the glass. Maybe some sort of anemone? Responds to movement.

2. What looks to be some sort of worm. This sample was taken from a scraping of live rock.

3. Scraping of coral tissue that had RTN'd.

Welcome to Reef2Reef!

1 - I'm not entirely sure. Possibly a Brachionid Rotifer? My first thought was a hydroid polyp, but it seems each tentacle is covered in cilia.

2 - Again, I'm not entirely sure, but I'm leaning toward a Dinophilid worm like Dinophilus taeniatus.

3 - Some sort of Ciliate (I really need to learn more about these at some point).

Thanks for the reply!

I thought hydroid too when I saw it on the glass. I suspect you are right after doing some more research. I've used rotifers in the past for clownfish breeding but I've never looked at one under a microscope. Pretty neat!

1. Agree it's one of the rotifer types that is attached.
2. I don't know what that kind is called.
3. that is a ciliate likely in the euplotes family. It's a larger member of that group.

the top - a goblet worm (Entoprocta spp.)?
middle no idea
bottom - could be an ostracod depending on what mag we're at
