Id/Whelk?

[Frigideus]

From TBS Live Rock. Is this a whelk or something else? It hasn't harmed any of my other snails but the snout looks patterned so sadly I think it is a whelk. What should I do with pests like this?

Never heard the term whelk, but looks like a nassarius snail to me. Good CUC member, burrows in the sand quite a bit and you can see the snorkel sticking out.

I got a few of these on my tbs rock a couple months ago. Haven't harmed anything that I can tell. They do seem to like tangoing with each other though.

May want to tag TBS. They are active here. It does look like a whelk to me with the mottled snout. They list this as undesirable on their critter id.

Looks like one to me; can you flip it and get a pic?

ok I don’t see the curl of the shell I was expecting- I’m sort of leaning towards nassarius now but definitely let some others chime in.

The tatttoed skin comment points to whelk

How do people dispose of pests? Watching it slowly die if I simply pull it out is kind of saddening, but I will hopefully wait for a couple more opinions before I send it to die.

Snout gives it away, whelk. Unlike nassarius you’ll notice it doesn’t go under the sand unless you feed like a nassarius.

Sump it?

Sump it?

i want to, but wont he just crawl back up to the display eventually? is it fine to keep him down there with copepods?

 

[billyocean]

Not sure....nothings impossible but probably quite improbable

You can put in in a bag then freezer, Vinegar bath, smash it, or 91% rubbing alcohol.

Great photos!
Whelks are very common hitchhikers and thankfully easy to remove.
Sump it, donate to a LFS or give to someone with a mantis shrimp.

I am almost certain it is a whelk! Sump it! Maybe @ISpeakForTheSeas can comment here!

Nassarius snails ARE whelks. Most whelks are predatory. Nassarius species are not. Nassarius is a genus, and there are like hundreds of different species of them.

Nassarius - Wikipedia

en.wikipedia.org

Nassarius, common name nassa mud snails (USA) or dog whelks (UK), is a genus of minute to medium-sized sea snails, marine gastropod molluscs in the family Nassariidae.[1] They are scavengers.

I saw this post earlier and didn't respond, because frankly given that there are so many different species of Nassarius, I am not qualified to tell you whether this one is one or not.

Definitely an undesirable whelk.
