 Tagged Horseshoe Crab (Limulus polyphemus)

“Horseshoe crabs are evolutionary survivors that have remained relatively unchanged in appearance for 350 million years,” begins the U.S. Fish and Wildlife Service information fact sheet on “The Horseshoe Crab (Limulus polyphemus) — A Living Fossil.”  As youngsters summering on Cape Cod, the Turtle Journal team remembers swarms of thousands of mating horseshoe crabs on beaches from Falmouth to Provincetown.  Wading in the tidal flats was transformed into an obstacle course as we stepped over myriad pairs of horseshoe crabs approaching the beach.  Today, populations have dwindled by orders of magnitude as these gentle critters have been harvested for conch and whelk bait, have been bled for medical research, and have been hunted and killed for bounties.  These inter-tidal roto-tillers provide a critical service for the estuarine ecosystem, and as you will learn in the fact sheets below, horseshoe crab eggs are a critical factor in some of the longest shorebird migrations on record.

Turtle Journal encourages you, too, to participate in these worthwhile research programs.  Whenever you find a tag in the wild, record the tag number, make a note of the telephone number, remember the location, and give U.S. Fish  and Wildlife a call.

In our hearts and memories, horseshoe crabs are a quintessential Cape Cod symbol.  And, between turtles at 300 million years old and horseshoe crabs at 350 million years old, we are fortunate to study living fossils that may actually have something important to teach their big brained yet less capable successors about LONG term survival.


Good News Sea Turtle Report from Florida Gulf Coast

Loggerhead Sea Turtle Deposits Eggs on Florida’s Gulf Coast

Turtle Journal received a sea turtle report from our colleagues in Southwest Florida this weekend, and we’re excited to share this good news durng a year that has witnessed unrelenting bad news about the Gulf environment and sea turtles.  We thank our friend, Ranger Randy Sarton of the Ritz Carlton in Naples, for thinking about his chilly turtle comrades up here in the Great White North as we patrol Cape Cod’s frigid beaches for sea turtles during our fall-winter stranding season.

Cold-Stunned Loggerhead on Vanderbilt Beach in February

Speaking of cold-stunning, Turtle Journal remembers that only last winter (2010), thousands of Florida sea turtles were caught in a miserable cold snap that sent them into hyp0thermic stupor.  This event called on naturalists, environmentalists, conservationists, scientists, researchers and willing volunteers to find these precious animals tossed randomly along Florida’s wide-spread gulf and ocean beaches.  In fact, Turtle Journal’s Sue Wieber Nourse contributed her share when she discovered this cold-stunned loggerhead sea turtle on Vanderbilt Beach in Naples, Florida in February 2010.

Of course we all remember that the Gulf Coast experienced an unprecedented ecological tragedy with the drilling platform explosion and leak this past year.  The effects of this disaster on sea turtle populations will not be fully measured for a generation.  Not only were mature, breeding animals affected, but oil drenched sargassum, which provides early nursery habitat for the most endangered sea turtle hatchlings in the world, was burned to remove oil residue from the sea.

Ranger Randy Sarton of Ritz Carlton’s Nature’s Wonders

Ranger Randy (Sarton) leads the Ritz Carlton’s Nature’s Wonders, one of Turtle Journal’s favorite stops whenever we visit the Southwest Coast of Florida.  Spending time in Nature’s Wonders and joining Ranger Randy for one of his many entertaining and informative programs makes a stay at the Ritz Carlton that much more pleasurable.  Once the stranding season ends here on Cape Cod, and the snows begin to pile into the Northeast from massive Arctic cold fronts, you can bet that Turtle Journal will be scanning Expedia for airline tickets to Southwest Florida.

Loggerhead Sea Turtle Crawl and Nest

Randy reports that for the 2010 sea turtle nesting season in Collier County, they had 765 nests compared to 510 last year (2009).  That’s a 50% increase in sea turtle nests in Collier county!

2010 Loggerhead Sea Turtle Nest on Ritz Carlton Beach

On Vanderbilt Beach, where Randy’s Ritz Carlton is located, he reports 111 sea turtle nests this year compared to only 60 last year (2009), which includes this wonderful nest pictured above directly in front of the Ritz Carlton.  (See Loggerhead Nest at Naples Ritz-Carlton Hotel.)  That’s an 85% year to year increase!  In addition to the nests, Randy reports 88 false crawls (abortive nesting runs) in 2010 against only 67 discovered in 2009.

Loggerhead Hatchlings Emerge

The end product of all the fantastic work that the Collier County team invests in saving sea turtles is when tiny hatchlings emerge and scramble towards the brightest horizon, which is either the gulf or the closest fast food restaurant.  Thankfully, the Florida lights-out policy augmented by a lot of help from dedicated volunteers ensures that most of Florida’s sea turtle hatchlings catch the evening tide rather than a burger and fries.

Juvenile Loggerhead Female in SW Florida Conservancy

We couldn’t resist closing this post with an edited video clip from the Conservancy of SW Florida from last February.  The film shows an exquisite young juvenile loggerhead in rehab at the conservancy and reminds us of what all this saving the world, one turtle at a time really means.


Thousands of Mermaid Purses Wash Ashore in Sandwich

Mermaid Purses (Skate Egg Cases)

As Turtle Journal continued sea turtle patrols this week, Sue Wieber Nourse encountered an interesting phenomenon on Sandwich beaches just west of Sandy Neck.  Lying within the high tide wrack were thousands of mermaid purses, skate egg casings, and hundreds of natural sponges.

Thousands of Mermaid Purses Wash Ashore

While it’s not unusual to discover tens of mermaid purses scattered in the wrack, or perhaps even a hundred on a long stretch of beach, the discovery of thousands, perhaps tens of thousands, of skate egg cases densely mingled in the wrack is quite unusual.

These mermaid purses are the egg cases of a skate (Raja sp.).  Sue holds one in her hands for comparative sizing.

As she walked along the beach, the density of skate cases remained the same for nearly a quarter mile.  Spot checking the egg cases, she discovered none with a baby skate still inside.


Giant Ocean Sunfish Discovered on Lieutenant Island

Ocean Sunfish on Lieutenant Island

A 7-foot diameter ocean sunfish (Mola mola) stranded on Lieutenant Island’s north shore.  The relatively fresh specimen was discovered by Lydia Adler Okrent as she walked the island beach.  Lydia sent photos of the animal electronically to her mother and island resident, Becky Okrent, now in Manhattan.  Becky in turn notified Turtle Journal that the animal had stranded, so that we could document the incident and derive scientific data from this unfortunate creature.  The stranding death of ocean sunfish along Cape Cod Bay beaches is an annual phenomenon that remains a mystery to researchers.

Ocean Sunfish (Mola mola) in Lieutenant Island Salt Marsh

This morning Sue Wieber Nourse of Turtle Journal visited Lieutenant Island to document the ocean sunfish.  This specimen measured 6 foot 2 inches from snout to the trailing edge of its caudal fin and 7 foot 7 inches from the tip of its dorsal fin to the tip of its ventral fin.  Based on examinations of many stranded sunfish over the last two years, we believe that these individuals that succumb to Cape Cod tides each fall appear to be relatively young, perhaps juveniles.  A necropsy of this specimen will be conducted to determine its gender and to gather more information on potential causes of death for these magnificent ocean creatures.

Should you find an ocean sunfish or any other interesting fauna on the beaches of Cape Cod and New England, please call our Turtle Journal hotline at 508-274-5108 or email us at theturtleguy@comcast.net. 

ADDENDUM

Early Tuesday afternoon “Krill” Carson conducted a necropsy of this animal and determined that it was a young female.

Wild Turkey Gangs Invade Marion Village for Thanksgiving

Halloween Pumpkins Stand Guard Against Wild Marauders

Halloween’s over and now garish pumpkins stand sentinel over Marion’s precious garbage.  Yet nothing, not even these ghoulish masks, seems to dissuade roving gangs of wild turkeys from invading our gentle town.

Wild Turkey Gang Rumbles through Marion Suburbs

Toms and Hens; Jets and Sharks; they stormed through quiet side streets of Marion’s upscale “Village.”  Where else in America are trash cans decorated with pagan totems for Monday pickup?

Rival Turkey Gangs Clash

Feathers ruffled as rival rafters crossed paths in the middle of the road.  You can almost hear the driving rhythm of Bernstein’s West Side Story echoing in the autumn leaves.

 Turkeys Distracted

Then, as quickly as it flared, the clash subsided when turkeys caught the whiff of oily pumpkin seeds.  Toms and Hens clucked and cackled in ululating unison, building bird-brained courage to assault another totem guarded treasure can.  Turtle Journal asks, “Can Thanksgiving come too soon to rescue our gentrified towns from the horror of rampaging gangs of wild turkeys?  Bring in your garbage, suburbia; the turkeys are coming!”
