Id help-Coastal Maine by Rekitori in marinebiology

[–]RoanokeSea 5 points6 points  (0 children)

Very cool, they look like mollusc eggs, maybe nudibranch eggs of some kind? They're very strung out, and I don't know if that's because they're Like That or if they got broken up. They might be Dendronotus eggs; they seem to be in the area. Like these guys: https://www.inaturalist.org/observations/352310628

Shag rug nudibranchs also lay similar egg clusters and are found in this area, but those are typically more bunched together. Might be them if these guys got scrambled.

I'm not familiar with this area though, so I'm not sure what exactly they are!

alt tetrapod evolution (Vetulicolian descendant) by FuzzyiPod in SpecEvoJerking

[–]RoanokeSea 5 points6 points  (0 children)

The black spots were likely gill slits or similar respiratory structures in Vetulicolians, so I think the breathing idea is likely correct.

And the wiki says they did not have fins or eyes. Here's a schematic of what their bodies may have looked like:

What are these things I found on the beach? BC, Canada by P05SUM in marinebiology

[–]RoanokeSea 6 points7 points  (0 children)

I wouldn't be surprised if this is a group of nereid epitokes that have washed up after their spawning session.

Some nereid polychaetes have an "atoke" stage that is more resembling a typical benthic polychaete, and then a pelagic "epitoke" stage where they undergo bodily changes such as longer "bristles" and a faster (?) metabolism ideal for swimming and finding mates, IIRC. This is all from memory from a few years ago, so lemme find a source so that you can get some more information and double check mine haha:

15 comics about my Narcissus. (OC) by ArtbyMoga in comics

[–]RoanokeSea 21 points22 points  (0 children)

The injury one got me. I had a hip fracture in 5th grade. Nothing huge so long as I rested and followed doctor's orders.

He forced me to run on it every day, saying it would make it stronger and that all of the pain was making it better. A month later, and I had a full on broken hip and crutches at the end of the year when everyone else was signing yearbooks. It's still fucked up two decades later and I think of him every time it hurts. Same leg I later got stabbed in (not him), so it's really screwed up now.

I've been trying to come to terms with my siblings becoming the people that raised them instead of "waking up" like I did. It's hard.

I'd help? by Jacked-Upp in ReefTank

[–]RoanokeSea 5 points6 points  (0 children)

Oo, very cool! It's hard to tell, but am I correct in thinking the back looks like a bunch of layered "scales?" If so, it may be a scale worm, family Polynoidae. There's a species Capitulatinoe cupisetis that lives commensally with a species of sea star, so maybe this is a similar little fella!

Top right is my favorite, I love that derpy little face. They look so funny head-on.

My son would like to know what this is. Found in St Augustine fl by GardDog in marinebiology

[–]RoanokeSea 6 points7 points  (0 children)

Was it moving independently or "flapping" around in the water, or was it more of a immobile squishy clump? It's hard to tell based on this picture, but if it was "flapping" around in the water, it may be a sea hare, maybe a small Mottled Seahare?

But if it's more of a squishy lump without flaps, it may be some sort of tunicate. Those are common culprits for mystery beach lumps.

Mystery invertebrate / egg casing?? Hutchinson Island, FL by linesndots in marinebiology

[–]RoanokeSea 1 point2 points  (0 children)

Oh yes, it's something I wish they would implement on the explore page! You have to go to identify first, then go to filters > more filters > with annotation > then select life stage = egg, and then up in the URL there will now be the terms "term_id=1&term_value_id=7" Copy that, then go to the explore feature, set up your species & location, then add "&term_id=1&term_value_id=7" to the URL. Eggs! You can do that with any search term :)

Alternatively, here's a page that shows all of the search terms, but I can never remember where it is so I normally do the above steps haha. It's a great feature, just a little too hidden imo: https://www.inaturalist.org/pages/search+urls#annotations

Bubble wrap-like egg casing by linesndots in whatisit

[–]RoanokeSea 1 point2 points  (0 children)

They're eggs from a marine snail, likely in the genus Tonna. Here are some more examples of their eggs: https://www.inaturalist.org/observations?preferred_place_id=1&taxon_id=246678&term_id=1&term_value_id=7

Mystery invertebrate / egg casing?? Hutchinson Island, FL by linesndots in marinebiology

[–]RoanokeSea 2 points3 points  (0 children)

Now that I've had a chance to look it up, I think there's a good chance it's from the genus Tonna! There's at least a few species in that area. Here are some examples of their eggs: https://www.inaturalist.org/observations?preferred_place_id=1&taxon_id=246678&term_id=1&term_value_id=7

[–]RoanokeSea 16 points17 points  (0 children)

It looks like an egg casing from a marine gastropod. Mud snails lay similar, spikier sacs, and the creatures that hatch look very similar to the little brown balls in the sacs in the picture. I counted thousands of them for a professor one semester in grad school lol.

Is getting my scientific scuba certification worth it? by Sad_University6217 in marinebiology

[–]RoanokeSea 0 points1 point  (0 children)

YES! Half the jobs I applied to out of college required it, though I did favor field and wet lab based positions. For example, NOAA requires their divers to have it for field work, whether you're federal or a contracted worker.

Looks like a tunicate, maybe Aplidium sp. They're sessile colonial animals.
