Seashell list from New Haven, Connecticut

On Friday, January 19th, 2018, a friend of mine (Charlie Whitman) drove Ed and I north from NYC to New Haven, Connecticut, to meet up with another old friend from Massachusetts (Jay Cordeiro), so that Charlie could give Jay a full set of "New York Shell Club Notes" to place in some deserving institution, since the NYC shell club is now, finally, defunct. It was a relatively nice day with temperatures in the 40s and a little sun, although there were still piles of ice around here and there, ice-covered ponds, slabs of ice on the beaches, and so on.

We all met up briefly in a small parking area not far west of the Long Wharf. Charlie and I noticed that on the shore below the rip-rap rocks there was a small sand beach with several very promising-looking full drift lines of mostly white shells. We could not spare any time to search the drift right then, because all of us except Ed and I needed to go eat at Pepe's Pizza.

However, when it was time to return to NYC, Charlie took a little detour back to Long Wharf Park, where he and I started combing the beach drift. It was now low tide and even more beach was exposed. The beach drift was far richer in species than we had imagined, so we spent almost an hour there. We also both took sediment samples home with us.

Here is what we found. The micro species are marked with an M.

Hydobia totteni -- numerous shells -- M
Littorina littorea -- several fresh shells
Littorina saxatilis -- one broken shell
Assiminea succinta -- one shell -- M
Bittium alternatum -- one broken shell -- M
Crepidula convexa -- several fresh shells
Crepidula fornicata -- live
Crepidula plana -- one shell
Neverita duplicata -- several shells
Eupleura caudata -- several shells
Urosalpinx cinerea -- several shells
Mitrella lunata -- one fresh shell -- M
Busycotypus canaliculatus -- four of them
Tritia obsoleta -- countless shells
Tritia trivittata -- some shells
Boonea sp. -- many shells -- M

Geukensia demissa -- live
Anadara ovalis -- a fragment
Anadara transversa -- one small valve
Argopecten irradians -- many fragments
Crassostrea virginica -- with flesh still inside
Mulinia lateralis -- one valve
Ensis directus --paried valves
Macoma balthica -- paired valves
Gemma gemma -- paired valves -- M
Mercenaria mercenaria -- paired valves
Petricola pholadiformis -- one valve
Mya arenaria -- paired valves

A total of 28 species of shelled mollusks! I am assuming that the drift on this little beach at Long Wharf Park is not normally so extremely rich in species -- perhaps this abundance of beach drift had something to do with the recent prolonged extreme cold snap as well as the snow storm / nor'easter that happened a couple of weeks ago.

We also found several other kinds of marine life:

Snail Fur
Atlantic Horseshoe Crab
Trumpet Worms
Bay Barnacle
Fragile Barnacle

Sea Lettuce -- Ulva lactuca

Two medium-sized juveniles. There were at least four on this beach and they were all the same size.

The shell at the top is the Convex Slippersnail.

The lower one is a very eroded Eastern Mud Snail.

These are really tiny - about 4 mm - but there were many thousands of them in the fine drift line.

This was found in a fine drift line. These tubes are quite fragile.

The "stubble" left over from a coating of the "snail fur" hydroid on the underside of this Neverita duplicata moon-snail shell.

That would indicate that it was inhabitated by a hermit crab after the death of the moon snail.

描述

This Eastern Oyster Drill shell has residue from the Snail Fur hydroid on it, and also a big notch on the columella, which indicates that a hermit crab lived in this shell for some considerable time.

I will try to see if I can take a photo that really shows the sculpture.

@kueda -- I thought you would find this interesting. There were no bubble shells or tiny tellins, but still we had a blast!

Neat, this looks a little more like the cast of characters I see at Hammo.

You mean Hammonasset State Park?

Have you looked on this Long Wharf Park beach ever?

發佈由 susanhewitt 超過 6 年 前

Such an enjoyable read! Thanks, Susan. :)

Yes, Hammonasset. Have not been to Long Wharf Beach (have been to the theater), but maybe next time I'm back in CT.

OK Ken-ichi, I hope you do well there when you do get to this beach.
