Public coordinates shown as a random point within 10KM of the true coordinates. True coordinates are only visible to you and the curators of projects to which you add the observation.
private
Coordinates completely hidden from public maps, true coordinates only visible to you and the curators of projects to which you add the observation.
open
Everyone can see the coordinates unless the taxon is threatened.
Description
We have a couple moon snails here, and two that are this large, so I can't be sure. Next time I'll check the book in the field!
WoRMS says Natica didyma is from Mozambique, and this snail was in Madison, Connecticut, USA, so I'm thinking it's not that. The limited field guide I had for intertidal inverts in the eastern US listed two moon snails, Polinices duplicatus and Lunatia heros, so I'm guessing it's one of those, but telling them apart apparently requires inspecting the shell aperture, which was kind of, uh, filled with snail in this case.
The size of the dish here was about 10 cm in diameter, so I guess the shell was around 4cm?
The data quality assessment is a summary of an observation's accuracy. All
observations start as "casual" grade, and achieve
"research" grade when
the iNat community agrees with the observer's ID, where an "agreeing"
identification is one that matches exactly or is of a child taxon of the
observer's ID. For example, if Scott says it's a mammal and Ken-ichi
says it's Homo sapiens, then Ken-ichi agrees with Scott.
the observation has a date
the observation is georeferenced (i.e. has lat/lon coordinates)
the observation has a photo
Observations will revert to "casual" grade if the above conditions aren't met or
the community agrees the location doesn't looks accurate (e.g. monkeys in the middle of the ocean, hippos in office buildings, etc.)
the community agrees the organism isn't wild/naturalized (e.g. captive or cultivated by humans or intelligent space aliens)

looks alike to Natica didyma
