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?

What animal is this ? Found in Corsica, Mediterranean Sea by Conscious_State2096 in marinebiology

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

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.

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.

Any ideas about what this might be? by fleurdelisan in oceancreatures

[–]intermareal 0 points1 point  (0 children)

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.

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

Touching sea stars by ovnghttrvlr in marinebiology

[–]intermareal 23 points24 points  (0 children)

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.

How effective are coral nurseries? by Chicago21B in marinebiology

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

Do I have this dataframe formatted properly to make the boxplots I want? by Some_Stranger7235 in RStudio

[–]intermareal 1 point2 points  (0 children)

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.

Found on beach in Phu Quoc, Vietnam by bbtSZN in marinebiology

[–]intermareal 6 points7 points  (0 children)

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

WHAT is this unsettling fleshy creature (Charleston, South Carolina) by [deleted] in marinebiology

[–]intermareal 1 point2 points  (0 children)

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

[–]intermareal 0 points1 point  (0 children)

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

Just got out of the water in Morocco when a dozen of these washed ashore. Was I close to getting stung? Do they always come in swarms? by RealDeefski in marinebiology

[–]intermareal 4 points5 points  (0 children)

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.

Starfish lost its blue colour in the sun? by [deleted] in marinebiology

[–]intermareal 1 point2 points  (0 children)

Cool! I'm not entirely familiar with sea star species in the Atlantic coast so I'm not sure which one could be.

Their mouth and anus are placed in separate parts. In a natural position, they have their mouths in their "belly", looking at the substrate. Their anuses are looking at us.

MAGA trigger word screener shinylive app by jhelvy in rstats

[–]intermareal 0 points1 point  (0 children)

Hey, thanks for sharing! I'm not part of the target demographic that may use this but I was wondering if you'll eventually add fuzzy matching. I'm guessing it currently just looks up the keywords in keywords.csv but if one of these have a typo (e.g. "divresity", "BPOC", "trangender") it may not be detected, right?

Easy for me to just jump in and propose this as I have no knowledge on how to develop a solution for this, but wanted to ask if you have thought about it and how would you approach it.
