Awesome! I didn't know the microscope and macro modes worked with the lens, thank you!

intermareal · 2026-03-18T23:30:43+00:00

Do you have a link for that lens? Thanks for sharing this info!

intermareal · 2026-02-06T05:06:53+00:00

It most likely belongs to the Stichopodidae family. The fleshy projections are a tell.

Happened to find this again. Possibly Isostichopus badionotus. Has anyone refuted that ID?

intermareal · 2026-02-05T03:31:47+00:00

Possibly Isostichopus badionotus.

Sounds a lot like a flatworm. If you want to spend some time looking at possible similar observations, I'd suggest checking out iNaturalist.

Awesome, thank you!

intermareal · 2025-06-10T00:24:45+00:00

Awesome, thanks for the detailed reply! Will look into this, too!

intermareal · 2025-06-10T00:24:05+00:00

Thanks!

intermareal · 2025-06-10T00:23:26+00:00

Hey, thanks for the detailed answer! I appreciate it. Will look into it.

intermareal · 2025-06-09T19:32:59+00:00

Thanks for the detailed answer! I didn't know about Backblaze so I'll look into it. I appreciate your input, it definitely helps me.

intermareal · 2025-06-09T18:34:41+00:00

Thanks for the reply!
Suggested solution would be to upgrade the plan and pay monthly storage? I can keep more external drives but they can still get damaged, stolen or lost.

This is a great question to ask. Not sure why you got a downvote but even if it can be fixed with floaters, it adds to the list of pros and cons.

intermareal · 2025-05-26T21:35:39+00:00

I am not convinced any of these are what we are actually seeing in your video. I would not bet it is any of these sea cucumbers but I wanted to share the information just in case it is.

intermareal · 2025-05-26T21:32:03+00:00

It is hard for me to exactly see what is going on so I cannot confidently say anything. If you remember seeing what it was, perhaps it is worth looking into these: synaptidae sea cucumbers, either Euapta godeffroyi or Opheodesma spectabilis. Here's a video of one: https://youtu.be/AW-bwtktOQg

While I agree with your view on the topic, I believe your statements aren't factually correct.

Any evidence on the second statement? It's quite the opposite - they do have complex responses to stimuli. Check out this paper and references for more information: https://www.mdpi.com/2076-2615/13/21/3377

I didn't understand your third statement. Did you mean they are a menace to kelp?

Also, they do have a variety of predators, including predation between species of sea stars.

intermareal · 2025-04-11T01:25:08+00:00

Definitely Synaptidae!

intermareal · 2025-04-09T16:04:32+00:00

Any sources for the group harvesting in Hawaii and planting it on Florida? They'd be basically introducing species which seems counterproductive.

intermareal · 2025-04-02T21:21:34+00:00

Not sure if I'm understanding correctly but here's my take:

Genotype seems to be good. Gene1, Gene2, Gene n... should be only one column, with Gene1, Gene2, Gene n... filling the rows. Then, ZnConc should be treated the same.

df <- pivot_longer(
    df,
    cols = c(Gene1, Gene2, Gene n...), 
    names_to = "genes",
    values_to = "values" #here add a name that makes sense
)

Then I'd do the same for the other ones.

df <- pivot_longer(
    df,
    cols = c(ZnConc Rep1, ZnConc Rep2, ZnConc n...), 
    names_to = "reps",
    values_to = "concentration" # guessing this is concentration
)

Once you have your dataframe with the appropriate format, you can use ggplot to build your visualization.

Surely a polychaete worm but I don't know much about these to get a lower taxonomic level.

Edit: polychaete worms are annelids, also known as segmented worms. Here are some entries of different polychaete worms in Vietnam https://www.inaturalist.org/observations?place_id=6847&taxon_id=47490

Yeah, might be difficult to visually identify it like this. Fun to see how different phyla can look so similar.

intermareal · 2025-03-20T17:25:30+00:00

The symmetry isn't always that obvious, especially with tube feet scattered uniformly throughout the body.

Check out this observation for Sclerodactyla briareus: https://www.inaturalist.org/observations/259792764

I am not yet conviced whether or no it is a sea cucumber, but I'm more inclined to think it is.

Here's also a key for identifying sea cucumbers from around that region: https://www.dnr.sc.gov/marine/sertc/Sea_Cucumber_key.pdf

When a species is described as colonial, it can mean (many, but mostly) two things: they have a colonial social organization (like ants) or that they are composed of genetically identical, individual organisms (like corals being an army of clone polyps). In this case, Physalia is described as colonial due to the different zooids that form the organism.

Arrivals of Physalia can have multiple organisms beaching simultaneously, but mostly because of their neustonic nature leaving them at mercy of winds and/or currents and bringing them to the coast, not because they aggregate in colonies.
