A Wee Bit Dangerous, a Whole Lotta Funny…

I recently spent the afternoon on a beach adventure with a friend, her daughter (also a friend), and her three girls. These girls have gone on a number of beach adventures with me and are growing up to be fine beach nerds, my protégés making Miss Mary so very proud.

We were walking alongside a series of deep tidal pools with the girls trailing behind when, hearing a bit of commotion, we turned around to see only the head of Protégé K sticking out of one of the pools. The first frightening thought for the three adults was that K had dropped into an exceptionally deep pool, but it was quickly obvious, with a huge sigh of relief, that she was just “swimming” in the pool.

We watched as her sisters, Protégés C and L were dancing around, cheering her on. But then the cheers and laughter became screams for her to get out. K  (and we) were momentarily confused, but then K was also screaming and running from the pool. We rushed forward, and peering into the water could see that the pool K had been swimming in, in fact, all of the tidal pools, were teeming with Blue Crabs, some of them VERY LARGE. K could have easily been the victim of the fierce claws of crabs just acting to defend themselves.

Once the hearts stopped racing, the laughter set in and we busied ourselves counting crabs and trying to scoop some up in our buckets for closer inspection. We even found what appeared to be a mating pair (the male was cradling the female). As the water settled and cleared in the pool K had been in, we saw that not only had she been swimming with Blue Crabs, but there was also unbeknownst to her, a fairly large Horseshoe Crab.

With the excitement done, when continued our adventures, and even catalogued a few new critters like Sea Pansies and a Sea Anemone different than what I have seen here before.

Now I have to share the VERY disappointing aspect of our day’s adventure- the TRASH. I always make it a habit to pick up trash while walking the beach, a habit the girls have also picked up (YaY!), and although some days I come back with more beach garbage than beach treasure, this day set a record for the amount collected, not a record we were happy to set.

I Knew Blue Crabs Were Fierce, but…

Pine Island in Hilton Head Plantation. This is the northeast corner of the island looking across the marsh to the sound. To my back was the mouth of Skull Creek.

I was walking the beach on Pine Island in Hilton Head Plantation this morning when I noticed a large Blue Crab just off shore. I stopped to look, because I always stop to check out the critters, and I could see that my friend was a female because of her lovely painted nails (claw tips). Next thing I knew a fin broke the surface and there was a small shark circling the lady crab. And this in water not much more than ankle deep- I know because I had stepped into the surf for a closer look. I thought she was a goner for sure…

The Amazing Horseshoe Crab

These amazing creatures predate the dinosaurs by millions of years. Although we refer to them as “crabs,” they are not crustaceans, and are more closely related to spiders than crabs. Because Horseshoe Crabs live in protected coastal waters, all photos were taken along Port Royal Sound on the north end of the island.

Horseshoe Crabs spend most of their lives moving along the ocean floor like a small tank, eating whatever lay in their way- fish, shellfish, worms, dead and decaying matter, and even algae. These animals have five pairs of walking legs and, a pair in the front, and one pair of pusher legs in the back used for swimming. (Did you know that they swim upside-down?). They have external book gills (so named because they sorta, kinda look like the pages of a book) that are used for breathing, but also assist with swimming.

This video is of the crabs swimming in the pooled water around the jetty at the heel of the island. You’ll notice smaller males clinging to the backs of the larger females. For more about the spawning of the Horseshoe Crabs, visit my post from May 7, 2016.

A New Page!!

The long promised page about our wonderful Atlantic Bottlenose Dolphin is finally live. Just scroll over Critters in the top bar and they will be the first in the drop down menu. Did I touch on everything you wondered about dolphins? Please let me know in the comments what you think, but be kind.

Horseshoe Crab Tagging Program

018

I found this live tagged female May 15, 2016 on Mitchelville Beach, just west of the sign marking the public shellfish grounds.

Horseshoe crab eggs provide an important food source for shorebirds, the crabs themselves are important to medical research and pharmaceutical companies, and they are harvested by commercial fishermen to be used as bait. The status of horseshoe crab populations along the Atlantic coast is poorly understood, but the crabs continue to be harvested. Although it is believed that horseshoe crabs are abundant, a decline in the population could severely impact shorebird populations that depend on the eggs for survival and severely impact medical uses of the crabs.

Each animal is tagged with a unique number and the tag includes both the phone number and website for reporting.

In 1999, the U.S. Fish and Wildlife Service initiated a coast-wide tagging program. Currently horseshoe crabs are tagged and released by researchers along the Atlantic and Gulf coasts as part of several on-going studies. This program provides data on distribution, movement, longevity, and mortality of horseshoe crabs. Data are used to inform management decisions about maintaining sustainable horseshoe crab populations. Proper management of horseshoe crab populations will benefit shorebirds, the biomedical industry and the commercial fishing industry.

The U.S, Fish and Wildlife Service views public involvement as an important factor in this program. If you see a Horseshoe Crab with a tag such as this, please call the phone number on the tag and report the tag number, or easier yet, just go online and fill out the Horseshoe Crab Resighting Form. Taking a picture as I did or writing down the numbers will aid you. A certificate of participation containing release information is sent to those who report horseshoe crab tags. You will also receive information about horseshoe crabs and shorebirds, and the first time you make a report you get an awesome pewter horseshoe crab pin.

My certificate and pewter pin came about two months after I reported the tag. I think maybe the release and recapture dates got swapped, but they still tell me that this particular lady was tagged almost a year ago to the day on the same stretch of beach.

The information sent with my certificate and pin. I had to laugh that the original address was Hilton Head Island, OHIO.
