Here to Stay!

Since the discovery of the Thrush Cowrie, Naria turdus, in Florida in December 2022*, several other findings of the species have been informally reported for the east coast of Florida, most between Palm Beach County and Key West in the lower Florida Keys. The Thrush Cowrie originates from the Red Sea and western Indian Ocean, and had been introduced to the Mediterranean and Caribbean seas. One of the most recent sightings of the species took place in the same general area as that of the first fi

Shell of the Week: The Jupiter Dondice

At 10 mm in length (a little less than 0.5 inch), the Jupiter Dondice, Dondice jupiteriensis García-Mendez, Padula, and Valdés, 2022, is one of the smallest (and most attractive) local species of nudibranchs (shell-less gastropods). The Jupiter Dondice has “moustache-like,” oral tentacles (left on image.) These tentacles can reach more than half the slug’s body length! The rhinophores, sensorial projections behind the oral tentacles, have irregular arrangements of rings on their upper half. The

Giant Squid Body Lift

One of the first tangible results of our renovation efforts at the National Shell Museum was the makeover of our Giant Squid model. The reduced-size replica of Architeuthis dux was hanging from the very tall ceiling of the Great Hall of Shells, probably too high for proper enjoyment, as visitors had to bend their necks to see the squid in its full glory. The model was restored by exhibit designer Raymond Rawls, of Gainesville, Florida. Raymond repaired arms and tentacles, applied new coats of (m

New Snail Named After Jimmy Buffet’s Song!

Very fittingly, a new marine snail was named this week after Jimmy Buffet’s best-known song, Margaritaville. Cayo margarita is a new species of worm snail from the Florida Keys reported by Rüdiger Bieler and collaborators that made the national news, including a nice article on CNN “Space + Science” online news. The bright lemon-yellow color of the snail’s “skin” provided the initial inspiration for the scientific name of the species. (And the genus name Cayo—low island, or key, in Spanish—honor

Shell of the Week: The Smooth Flame Scallop

The Smooth Flame Scallop, Ctenoides mitis (Lamarck, 1807), is not a true scallop, but a member of the file clam family Limidae. It can can reach in excess of the 70 mm (about 2.76 inches). Its shell is relatively thin, bears a large number of fine radial ribs, and a thin brown periostracum. The Smooth Flame Scallop can be distinguished from the generally similar Rough File Clam, Ctenoides scaber, by the larger number of ribs. The species can be found off the coast of Florida, the Florida Keys, a

She’s Got Giant Squid Eyes!

As part of the National Shell Museum renovation process, our Giant Squid model will be receiving a facelift. The squid was added to the Museum’s Great Hall of Shell in the late 1990s, there is inevitable wear and tear, and so much more has been learned about the species (Architeuthis dux) in the last two decades. The model will receive a new paint job, arms will be re-attached, and new, more realistic eyes will be added. Giant Squids may attain 40 feet in length, and their complex, vertebrate-li

Green Mussels on Marco Island

National Shell Museum collaborator Amy Tripp recently sent this great photo of a few Green Mussels, Perna viridis, on a dock piling at the south end of Marco Island. Young Green Mussels have a brilliant green color, and adult shells, reaching as much as 4 inches, are brownish with bright-green margins.The Green Mussel originates from the Indo-West Pacific region, but was introduced, probably via ship hulls and/or ballast water, to the western Atlantic Ocean and other coastal waters of the world’

Shell of the Week: The Dwarf Planaxis

Hinea lineata is a small gastropod that reaches only about 10 mm (0.4 inch). The shell is smooth, and typically with narrow, brown spiral bands set against a cream-colored background. The species is found intertidally (between low and high tide lines) from East Florida, Bermuda, Bahamas, throughout the Caribbean south to Venezuela, and mid-Atlantic oceanic islands.

Shell of the Week: The Giant False Coquina

Iphigenia brasiliensis belongs to the coquina family, the Donacidae. Its shell reaches 66 mm (about 2.6 inches) and resembles a larger version of the local (in Florida) Variable Coquina, Donax variabilis. Its shell has a thin, smooth, light-brown periostracum (the outer layer). The wedge-shape of coquina shells help during quick burrowing in the sand. The species inhabits estuarine areas in Florida, teh Gulf of Mexico, and the Caribbean south to southern Brazil. #iphigeniabrasiliensis #iphigenia
