Scallop Shells Collected on the East Coast

While photographing my newly collected shells the other day, I decided to re-photograph my pretty scallop shells. Florida waters can contain a variety of types of scallops, but the shells I find over here on the east coast are mainly the Atlantic Calico Scallop.

Ponce Inlet, Florida’s central east coast

While beachcombing in my area of Florida, the best shells are often found around Ponce Inlet and the jetty area. Because of the rough surf and strong currents many of the shells are broken, worn, or have turned black. When I say “best shells” I mean the most unusual or rarely seen while I search the sand. I sometimes find olive shells here, big angel wings, scallops, and bits of coral. On this day, I found a pretty little pink scallop and a couple that were blackened from being buried in the sediment for a long time.

Photographing Scallop Shells

Sometimes photos can show a clearer picture of the intricate details of a seashell. The calico scallop, when found before it’s colors fade or turn black or orange, is quite pretty. I have a few of those and you can see the color variety in my photo below. Colors tend to be off-white, cream and yellow with blotches of maroon and pink.

Notice that some of the “ears”, or protrusions at the front of the shell, have worn down or off completely on some shells.

I’ve taken some macro photos to show the ribs on the shells a bit better. Other types of scallops that can be found in Florida waters are the Zig Zag and Round Ribbed, Rough Scallop, Scaly Scallop and famous Lion Paw (very rare). The Bailey-Matthews Museum on Sanibel Island has come good photos Florida’s scallops. See the set under the Family Pectinidae on their site.

The Round Ribbed and Zig Zag scallop have flat tops so as a bivalve each side looks different. You may find the colorful flat piece or the bottom, less colorful part. The Scaly scallop is more elongated and one of it’s “ears” is much longer than the other.

Bay scallops are now rarely found, according to the Living Beaches book (affiliate link to Amazon, new book version). Their ribs are more squared, but when I look at photos I can’t really see much difference between the Bay and Calico as far as shape. Because the Bay Scallop is now rare, I assume my shells are all Calico varieties.

Collecting the Popular Scallop Seashell

One of my favorite seafoods is scallops.  I never used to think much about their shell, until I began to find them along the beach.

The scallop is rounded in shape with protruding flaps at the hinge area (they are bivalves).  Sometimes the flaps are similar in size and sometimes one is much larger than the other (Scaly Scallop). Sometimes they are worn and barely visible.  Ridges fan out from that front point and can be thin, wide (Lion’s Paw), rough (Rough Scallop), or flat (upper part of the Zig Zag and Rough Ribbed scallops).  Sometimes each half of the shell can look entirely different.

Here in Florida there are a few varieties of scallops.  Probably the most common type is the Atlantic Calico Scallop (Argopecten gibbus).  Shells are colorful in shades of pink and purple with other possible colors like yellow and orange.  The entire shell can be colored, or it may have splotches or patterns of color over the shell.  This type is what I find on the East coast where I beach-comb. Size is usually around 1-2 inches.

One of the most unique looking scallop is the Kitten’s Paw (Plicatula gibbosa).  It’s a tiny shell which is a bit thick and bumpy with more irregular ridges.  The ones I have collected came from the Sanibel Island area.  They are off-white with orange, or sometimes yellow, coloring with cross-hatch type markings.  I have never found one on the East coast of Florida where I live, but my reference book claims this scallop lives all around the state.

The Atlantic Calico Scallop (Argopecten gibbus) is probably the most commonly found scallop shell in Florida. I’ve collected them on the west coast and east.

The brightly colored calico scallop shells in my photos above were collected on the West / Gulf coast of Florida. In comparison, the shells in my photo below (Calico shells only) were collected on the East coast. Shells in the Gulf area tend to be more well preserved as they are not churned up in the waves like on the Atlantic side.

The black scallop shell was collected from the Ponce Inlet area. I’ve written a post about black shells, because black is not the normal color for seashells.

Links to Other Types of Scallops Mentioned Here


  • Atlantic bay scallops (Argopecten irradians) – can be larger than the calico and will reach 4 inches across.  They are less colorful than calico also, and will be white, orange or grayish brown.  These used to be very common all around Florida and now are not.
  • Scaly scallops (Caribachlamys sentis) – are small (1.6 inches) and more pointed.  Their outstanding characteristic is that one of the front flaps is very large.  (The link also shows other types of scallops which I mention in this post.)
  • Zigzag scallops (Euvola ziczac) – are flat shells (top valve) with colorful zig-zagging colors of purple, pink or orange. They can be up to 4 inches wide.  The bottom part of the shell is rounded like a regular shell. (See a good photo in that link.)
  • Round-rib scallops – look similar to the Zigzag and also flat, but their ribs are wider. They are smaller than the Zigzag at max 2 inches.
  • Rough scallops – This type is rarely found on beaches. Usually they are solid colored and only grow to 1.5 inches. They have rough ribs, with tiny bumps, hence the name.
  • The coveted Lion’s Paw is a scallop shell with extra wide ridges.  It is not commonly found anywhere here in Florida, but it is possible to find one.  Your best chance of finding a Lion’s Paw would probably be over by Sanibel Island on the Gulf.
