SHELL OF THE MONTH JULY 2012

When B.C. Burgess wrote his monumental book “The Living Cowries” in 1970 little was known about the South African endemic cowries. In fact according to Burgess there existed no live collected specimens of either Cypraea fuscorobra or Cypraea edentula. In the years that have passed, SCUBA has become much more prevalent and live specimens of all the South Africans are available. Still they are anything but plentiful on the market. At the Cape of Good Hope the Atlantic and the Indian Oceans converge. All the major mollusc families have members indigenous to the area. Cypraea fuscorobra and Cypraea edentula are members of the genus Cypraeaovula, Gray 1824. Both belong to the “algoensis” group. Cypraeaovula are noted for ecological variations and hybridization. Some are quite difficult to identify, even with a guide book. Cypraea edentula, Gray 1825 lacks teeth and is called, as to be expected, the Toothless Cowrie. It is commonly between 18 and 24 millimeters in size. Small specimens are more available than large ones. Cypraea fuscorobra, Shaw 1909, has the boring common name of “Reddish Brown Cowrie.” It is rather globular in shape with a large callous and larger in size, the average being between 30-36 millimeters. Both retail in the $15 to $25 range. Choice specimens, especially of Cypraea edentula are hard to find. Both are prone to stress marks across the dorsums. Our two specimens both collected this year are donated by Richard Kent. They were acquired direct from a South African dealer, are of superior quality and fine starters for a South African collection. Many of the closely related and similar looking species are considerably more expensive and very difficult to acquire without a direct South African source.

SHELLERS JAMBOREE OF 2012

The Shellers’ Jamboree was held this past Memorial Day weekend. As always, the Clearwater club, worked very hard and we had an interesting weekend.

 Beginning on Saturday morning there was a 4 hour flea market where registrants could sell items. While we were getting settled in, there was Shell ID, Shell measuring and the silent Auction.

There were old acquaintances to greet and in our packet two word searches and a word Scramble. A packet of cartoons where we were asked to provide the captions was also included.

The festivities began after lunch with a spoof on shell collectors from different clubs, with our own Bob and Alice Pace donning fishing gear and “fishing” for shells. After that we had lunch.

The first program was Rick Batt speaking about Sand. Different beaches were explored including glass sand. That was followed by Dennis Sargent on “The Discovery and Description of a New Conch Species”.

After the first two programs we had a game called the BEACH Shell Hunt. We had teams based on our name tag colors and had to come up with as many names as possible using only Genus or Common Names. Anne Joffe was captain of a team, consisting of Jose Leal, Bill Lyons, Jim Cordy, Rick Batt and myself. We came up with 67 names for the highest score. Yea TEAM!!!

After the game, Dr. Jose Leal gave his program “Cowries: Natural History, Diversity and Cultural Impact.”

A game was played involving small bottles of sand with 40 items buried in them. We had to see if we could find all 40 items. It was quite interesting as objects would show themselves and then hide again.

Shortly after that the Silent Auction ended and we had a Happy Hour and our dinner buffet.

After dinner Anne Joffe, gave a program “Shelling in Guaymas, Mexico.

At that, our first busy day ended and we all retired to our motel rooms.

Sunday everyone who wanted to entered the Snail Parade, Coastal Creations and Treasures of the Sea. Another Silent Auction began. The first program was Morums A to Z, by Dr. Harry Lee. We then had a verbal auction with any extra monies going to Bailey-Matthews Museum. At 12:30 we had a BBQ lunch.

After lunch, Carole Marshall gave a program “Micro mollusks of South Florida.” That was followed by “Shelling in the Philippines” by Doug Jeffrey.  We then had the show awards given out and the end of the Silent auction.

That evening there was a banquet with a program “Living Shells” by Charles E. Rawlings, who also had his book for sale.  As a table favor we each had a lovely poem at our place setting, and then the Raffle tickets were pulled.

A high point of the banquet was that Linda Sunderland and I both won a raffle prize. Linda won a huge Melo and I won a lovely diorama made by the late Bob Pierson.  That was the end of a very busy Jamboree and an enjoyable reunion with many friends I don’t get to see enough.

I was sorry that not more Broward Shell Club members did not attend.  I hope if there ever is another Jamboree, more of our members will attend.

SHELL OF THE MONTH JUNE 2012

Clanculus puniceus (Philippi, 1846)  –  “The Strawberry Shell” – set of 6. Collected in Madagascar.

The Strawberry Top is one of the most “collectible” of the top shells, mainly for its wonderful, rich red coloring. Not many shells have a color like this! As a matter of fact, this shell was featured in our newspaper article show publicity a few years ago….and by the first day all of the dealers who had the shell in stock were sold out! The Clanculus are part of the Top-Shell Family, Trochidae. It is a very large worldwide family with numerous genera and hundreds of species. Most are top shaped (hence the name), but many are also “button” shaped and some even resemble Abalones. They have an iridescent interior and a round, many-whorled horny operculum. They occur from tidal rock pools to the deepest portions of the oceans. Most feed on seaweeds but many eat bryozoans and sponges.

GAINESVILLE FIELD TRIP

WHAT: A trip to Gainesville to see behind the scenes in the Department of Invertebrate Zoology. The second largest collection in the United States is housed here. We will meet with John Slapcinsky and tour the section. Later we will go behind the scenes of the Paleontology section. A trip to the Forida State Museum and their exhibits, for a slight extra fee, you can tour their Butterfly Garden.
WHERE: The weekend of July 27, 28 and 29. Leave Friday night, come back Sunday.
WHEN: Stay at the Paradise Motel on Hwy 441, just 1 1/2 miles from the Museum. The rates are really excellent, less than $50 per night, rooms with 2 queen beds. Lounge and Restaurant in the motel. Swimming Pool, balcony for poolside rooms. Poolside is a little extra. I will have a menu from the Restaurant at the next meeting.
Plans are a little sketchy as it will depend on who wants to go and what the majority want to do. Here is the bare bones:
Leave Friday July 27, meet or carpool or rent a van, depending on the majorities wishes. Stay at the Paramount Plaza Motel, which is about 11/2 mile S. of the turnoff to the Museum collections on 441. There is an ad in the Florida Roomsaver magazine for one King or 2 double beds room at $42.99 per night, plus taxes etc. That is still pretty reasonable. Plus there might be an even better rate as it is off season.
I have never stayed there, but they let me look at one of the rooms and it is very nice. Saturday morning go to the collections Department for a tour. Depending on the timing, we will go to lunch. Also we should have time to either go to the fossil collections department or to the actual public museum with butterfly gardens. Sunday we will possibly do again, either the fossil collections or the museum, whichever we did not do the day before. Depending on the time we can either leave for home or try to go to Blue Springs or Ginnie Springs for a short while. Again, it is up to the participants to determine.
The variable factors are: how many people want to go by themselves or want to chip in and rent a car. Let me know at the next meeting if you wish to go.

JETTY REOPENS TO PUBLIC

On Monday, April 16th, 2012, the rock jetty on the North end of John U. Lloyd State Park has been reopened to visitors. They have also opened the northernmost 200 feet of beach, which has been closed to the public for at least 7 years. Maybe some good shelling on untouched beaches? This also means that snorkeling along the South side of the rock jetty is allowed for the first time in years, if there aren’t too many fishermen there. If you have your Salt Water Fishing License, you might be able to collect live shells (as the fishermen are collecting live fish from the park). I heard in the past that Trivia nix (now named Niveria nix) – the little solid-colored Trivia – are found live there. -submitted by Tom Ball

DANIA BEACH—
For more than seven years, a lack of money and a lot of bureaucratic wrangling left one of Broward County’s best sightseeing spots off-limits to all but crabs and laughing gulls.

Clare Frost, a Dania Beach native, felt the loss of the 1,000-foot rock jetty at John U. Lloyd Beach State Park. “Standing out there is as close to going to sea as you can get without having a boat,” said Frost, 54.

At 2 p.m. Monday, it opened once more, fresh from a $700,000 makeover that includes a new paved walkway on top, stainless steel railings and six designated fishing spots for the disabled.

The reopening comes just in time for the 23rd annual Fleet Week, which begins April 25, and the Air & Sea Show, which returns April 28 after a 5-year hiatus.

“Being able to stand 50 feet or so from a moving ship, a warship or one of the largest cruise ships in the world, like the Oasis of the Seas, is pretty awesome,” said Carmelo Duesler, a park ranger for 28 years.

The jetty, jutting into the Atlantic Ocean to form the south side of the Port Everglades Inlet, was deemed unsafe and closed in October 2004. Repeated bashings from storms, including hurricanes Frances and Jeanne, had caused some of the underwater rocks to shift and the blacktop walkway to crack.

Although it lies within a state park, the jetty is owned by theU.S. Army Corps of Engineers, and the number of state, federal and local agencies with an interest in the rock pile made deciding how to fix it, and who should pay, a nightmare to figure out.

“It was very frustrating to tell people the jetty was closed and that there was no money to fix it,” Duesler said. “They would get angry. I just tried to explain that we had to do whatever we could to keep it safe.”

After years of inaction, Jeff Raley, coastal project manager for the state’s Department of Environmental Protection, led the push to break through what he called “the quagmire of having so many parties involved.”

He helped find a $350,000 grant from the Florida Inland Navigation District, $200,000 from Broward County’s Department of Environmental Protection & Growth Management and Port Everglades, and $150,000 from his own agency.

The work was done in less than four months. Pac Comm Inc., a Miami marine contractor, packed the underlying rocks with sand, hauled in granite fill from Tennesseee and Georgia to plug leaks, and then capped the structure with a smooth concrete walkway.

The contractor also built two groins south of the jetty to slow beach erosion.

“This is a flagship project for us,” said David Juelle, Pac Comm’s director of operations.

The jetty’s importance to the park was plain to see in attendance figures. Visitors dropped by more than 100,000 a year after its closure, said Duesler. The reopening now will mean up to 150,000 more park visitors, with an annual economic impact of $5.9 million, according to state estimates.

Frost, her husband Clive Taylor, 69, and other local residents plan to join a host of public officials Monday for the ceremonial ribbon-cutting.

“When we were kids, there was no walkway on top,” said Frost. “You had to jump from rock to rock and you always got wet. Now the jetty is perfect for families, for children, picnics and fishing. And when the big ships come by, it’s great enterTainment.”

PADI Project Aware:
6 – 9pm (Tuesday, May 8)

Description:
This is a formal, but fun, introduction for divers and non-divers alike to the plight of the world’s aquatic ecosystems. It is offered to anyone who wants to learn more about, and take responsibility for, marine and freshwater environments. Although diving and snorkeling offer the best avenues to appreciate the aquatic world, you do not have to be a diver to participate in this Project Aware presentation – it’s open to everyone. The only requirement is an interest in learning more about the 70% of the earth covered in water. A knowledge review will be administered at the end of the class and all participants will receive a resource CD-ROM of images from the course for future reference. A PADI certification for the Project Aware Specialty course will also be available for a fee of $20.00 to cover the cost of the materials, but will not be necessary for participation in this seminar.

Marine Invertebrate Identification:
6 – 9pm (Tuesday, May 15)

Description: The most common sea sponges, octocorals (soft corals), crustaceans, echinoderms and mollusks that you are likely to encounter while diving or snorkeling on southeast Florida’s coral reefs will be introduced in this course. A knowledge review will be administered at the end of the class and all participants will receive a resource CD-ROM of images from the course for future reference.

Stony Coral Identification:
6 – 9pm (Tuesday, May 22)

Description: This course will introduce you to thirty species of stony corals found offshore Miami-Dade, Broward, Palm Beach and Martin counties. A knowledge review will be administered at the end of the class and all participants will receive a resource CD-ROM of images from the course for future reference.

REEF Fish Identification:
6 – 9pm (Tuesday, May 29)

Description: This is a beginner course that teaches the basics of “fish watching”, including how to identify 50 commonly sighted species in the tropical western Atlantic. All materials are provided. An evaluation will be conducted at the end of the training. Anyone scoring 80% or better and who goes on to complete two fish surveys can become an Experience Level 2 volunteer for the Reef Environmental Education Foundation (REEF). The REEF Fish Survey Project is a volunteer fish monitoring program that enables volunteer SCUBA divers and snorkelers to collect and report information on marine fish populations. The data are collected using a fun and easy standardized method, the Roving Diver Technique (RDT), and are housed in a publicly accessible database on REEF’s website. Data collected by REEF volunteers are used for public education and by a variety of resource management agencies and researchers. For more information on REEF, go to: http://www.REEF.org.

SHELL OF THE MONTH – MAY 2012

Pterynotus miyokoae, Kosuge, 1979
Tangle nets at 100-150 m deep
Olango Island, Cebu, Philippines.
2009  SIZE about 60mm

It sure is a mouthful to pronounce the name! Pterynotus miyokoae is one of the most spectacular of the murex with elegant “wings” and marvelous delicate sculpturing. Scholars debate how it ended up a Pterynotus, with some saying it should be a Chicoreus. Other Pterynotus shells are awkward in appearance, misproportioned with their wings irregularly developed. Miyokoae are brown banded while Pterynotus are solid white or pastels. Pterynotus are very variable whereas the miyokoae are amazingly consistent. This was a very expensive shell when Kosuge described it in 1979 but prices have greatly declined. As all miyokoae look exactly the same, the lack of variety has reduced the value. It is indigenous to the Philippines where recently albino populations have been discovered.
