Whelk or nassarius

[Tlonghorn]

Well I recently got 2 "nassarius" snails but now I'm questioning that labeling and was wondering if I could get some help finding out it if they'll eat my snails (excuse picture quality camera phone) and it should be noted they do bury

i'm leaning nassarius but its a close call. How quick are they across the sand? My nassarius were like race cars.

My personal opinion is definately nassarius. Maybe jedimasterben will chine in. I know he just went through this

im going whelk, just for the "tattooed" pattern on it.

Whelk vs Nassarius

 

 

I'd say Whelk based on the trap door you can see on it's tail.

I have both whelks and nassarius snails. The large foot of the nassarius is obvious to me. My whelks have a suttle snail shape difference and a much smaller foot much. It be a couple days before I can get pictures for you. JMB or amphipod need to chime in

Technically, nassarius are whelks, they just specialize in detritus. If you want to be sure if its nassarius or not, put something alive near the snail. A whelk will kill it. A nassarius must wait for it to die.

I found a video. 1:32 you can see my "chestnut" nassarius climb the glass and eat some mysis

I vote nassarius. Honestly, yours looks exactly like the black nassarius you can find on Ebay. I think they're cold(ish) water? The whelks I have are fuzzy and look just like this dude:

True. I don't trust any of them

 

I guess the other question is do you have any bivalves or clams? If not, its probably not a big deal anyway.

I have 2 whelks that look similar to this. Which have been model citizens. I'll post tonight when.I get home

[SunWyrm]

I've never noticed mine except when I find them in my sump or QT. But then again I haven't tried to keep clams in a while.

My snails were very much not photogenic last night
