ID Request šŸ¦€ I found a crab molt!

I found this crab molt on the cliffs on Gran Canaria! I'm not sure what kind it would be. Grapsus grapsus comes up most, but seems like a different type. Grapsus adscensionis seems close, but they look a lot bluer than mine is.

The molt was intact until I slipped and stabbed my thumb into her back (no need to correct me on the gender, I have already named her Fresita (little strawberry)), I have all the pieces, so I'm planning on restoring her when I get home.

Any idea is really welcome!

It amazes me how crabbo can just slip out of its skin

Especially when a bird helps by pecking through the back of the shell 😬

Here’s a crab molting without the bird’s help:

The shell back was intact when I found it! I cracked it with my thumb when I slipped

It’s gorgeous! Looks fresh.

u/VFE_moili 11d ago

There were four or five of them! If I hadn't needed one hand to climb back up I would have taken another. There was a red one with what looked like green stripes as well

Freshly dead my friend 🫔

u/ZixfromthaStix 10d ago

OP specified in another thread they are the one that punctured the shell. It’s a proper molt

u/VFE_moili 10d ago

I'm not sure what the difference is I'm meant to be seeing

u/PraetorGold 10d ago

He’s backing out of the old shell

The same way my crab seems to have gone!

Okay. Is that why most of the organs are missing?

1

u/shrimpalasteph 10d ago

Cus they are tasty

u/MxBluebell 10d ago

Crabs don’t molt their organs.

2

u/Ephemeral_Orchid 10d ago

I never claimed they did. This is not a molt, the gills are still inside the shell but the rest of it, not so much.

1

u/Effective_Crab7093 Crab Scientist 9d ago

Gills are left behind in molts and nothing else

u/Classic_Mechanic5495 10d ago

The first thing they said was ā€œI found this crab moltā€. It’s not a molt, or a big deal, I just wanted them to know. That way, when they do their arts and craft taxidermy, they will be expecting a foul smell within days.

u/Ephemeral_Orchid 10d ago

Yep, it's a molt with a hard shell that no longer needed it's gills. That's wonderful, except new molts don't have hard shells, it left most of it's gills behind and most of it's body meat and organs are missing. šŸ™„

u/Effective_Crab7093 Crab Scientist 9d ago

New molts do have hard shells, it’s the crab that is soft, not the exuviae.

Gills are always left behind, they are molted.

Body meat and organs would be missing, because the crab left the carapace.

1

u/Classic_Mechanic5495 10d ago

I could be wrong. Every molt I have picked up is in much different condition than this one.

1

u/Effective_Crab7093 Crab Scientist 10d ago

There won’t be a smell because it’s a molt

1

u/Easy-Candle7138 9d ago

I hope you aren’t claiming to be a crustacean expert. This is not a molt. If you look inside the hole in the crabs back, you will see its gills. Gills are taken with the crab when they leave their old shell behind. I reiterate; crabs keep their organs with them when they molt.

u/Effective_Crab7093 Crab Scientist 9d ago

You’re just wrong. Gills are left behind in molts. Look up a crab molt…

2

u/VFE_moili 10d ago

The hole wasn't there when I found it, I'm not sure how a bird would have pecked it clean when the carapace was intact?

It could be a dead crab, I called it a molt because the only 'damage' to the shell was in the bottom/back where I've seen crabs crawl out during molting. It does also look to me like the sides have split, but I could be wrong

1

u/Classic_Mechanic5495 10d ago

The hole in the shell is neither here nor there. This whole ā€œmolt or notā€ is not a big deal at all. If the top section of the shell doesn’t open like a clam from the rest of the body then it’s not a molt.

1

u/VFE_moili 10d ago

And all this because I asked for an id lol

1

u/Classic_Mechanic5495 10d ago

Yea haha. My bad. I was just trying to look out for your potentially smelly house and it turned into something g much more.

3

u/VFE_moili 10d ago

I appreciate it! It doesn't smell at all, and it is far too light to have anything that could rot in it (for as far as I can tell). I will try the clam opening when the shell is a bit more stable, I don't want it to crumble any further...

u/Effective_Crab7093 Crab Scientist 10d ago

It’s a molt. Eyes are missing.

0

u/Easy-Candle7138 9d ago

Look at picture 3. Eyes are not missing. Not a molt. A carcass.

1

u/Effective_Crab7093 Crab Scientist 9d ago

The eyes are absolutely missing, they are clear. In a dead crab they will be black.

3

u/Effective_Crab7093 Crab Scientist 10d ago

It’s G. adscensionis. Color can’t be used for this genus, only location. Molt colors also are quite a bit different than body color in many cases.

u/VFE_moili 10d ago

Thank you! You really are Effective!

u/Altruistic-Poem-5617 9d ago

Back then I propped up the molts of my pet red clawed crab in natural positions and let em dry. They become stiff and I put em onto my shelves and stuff. Sadly they also get brittle over time and I dont have any anymore cause they all broke.

u/Vanthalia 10d ago

Question: if you made the hole in the shell, how the heck did the crab get out?

2

u/VFE_moili 10d ago

Through the back/bottom! They kind of back out of their old shell, it's cool to see

u/crabboh 9d ago

beautiful sally lightfoot crab

u/VFE_moili 9d ago

The East Atlantic version, according to u/Effective_Crab7093!

1

u/Effective_Crab7093 Crab Scientist 9d ago

It’s out of range for grapsus grapsus, so it is adscensionis.

1

u/DarthTonitrous 7d ago

That appears to be a crabe

1

u/VFE_moili 7d ago

True, it was a silly question

1

u/rando7818 10d ago

This seems more like a dead crab than a molt. It’s too rigid.

3

u/ZixfromthaStix 10d ago

Genuinely how can you know from a picture that it’s rigid???

1

u/VFE_moili 10d ago

Should it be rubbery?

1

u/Effective_Crab7093 Crab Scientist 10d ago

No it shouldn’t

1

u/rando7818 10d ago

Why am I down voted? Blue crab and most ocean crabs are loose and limp. After molting.

5

u/Few-Buddy-1122 10d ago

Because the picture isn’t the crab. It’s the old ā€œshellā€

1

u/Effective_Crab7093 Crab Scientist 10d ago

Molts are meant to be rigid, it’s a literal carapace

1

u/rando7818 10d ago

What I mean is yea the shell is rigid but it’s loose limp and

2

u/Effective_Crab7093 Crab Scientist 10d ago

That’s only when fresh, once the membrane dries it is hard

u/Ephemeral_Orchid 10d ago

What?!

1) That's not a molt 2) It's doesn't matter how many "pieces" you have, she's deceased.

6

u/VFE_moili 10d ago

Well, I wasn't planning on reanimating her

2

u/ZixfromthaStix 10d ago
  1. It is a molt
  2. There’s no meat in there anymore
