Red sea urchins lining the seafloor can “see”….

Sea urchins may use the entire surfaces of their bodies—from the ends of their “feet” to the tips of their spines—as huge eyes.

Scientists had already known the marine invertebrates react to light without any obvious eye-like structures—raising the question of how the animals see.

Previous genetic analysis of the California purple sea urchin had revealed that the animals possess a large number of genes linked with the development of the retina—the light-sensitive tissue lining the inner eyeball in people and other vertebrates.

This and other research suggested that sea urchin might rely on light-receptor cells randomly scattered across their skin, which collectively function like retinas.

Scientists had theorized the animals’ spines simulate the light-blocking pigmented cells found in most animals’ eyes. Because light-receptor cells in the retina can soak up light from every direction, pigmented cells work to block light from the back and the sides so animals can “see” what’s in front of them.

Now, however, the scientists have found two distinct groups of bristly, light-receptor cells concentrated at the bases and tips of the purple sea urchin’s 1,400-plus tube feet. These long, suction-tipped tubes, located on the undersides of sea urchin bodies, help the organisms move.

The team suspects that sea urchins use their tube feet as retinas and the rest of their bodies to shield against the extra incoming light, said researcher Maria Ina Arnone, a developmental biologist at Anton Dohrn Zoological Station in Naples, Italy.

Prior studies did find the number and placement of spines on a sea urchin could affect how sharp its vision might be, and this new find “might well be part of the picture,” Arnone added.

Sea Urchins..what you need to know..

Sea urchins (class Echinoidea) are animals with a round, rigid skeleton (test) made of interlocking calcite plates. The test is hollow inside, containing its various organs, and covered with lots of spines on the outside. They belong to a bigger group of animals called the spiny-skinned animals (phylum Echinodermata – “echino” roughly means “spiny”; “derma” roughly means “skin”). Examples of other echinoderms include sea stars, sea cucumbers, and feather stars.

long-spined sea urchin (Diadema setosum)

The spines can come in various forms – long or short, smooth or rough, sharp or blunt. They not only help the sea urchin to move, but deter predators as well. Some sea urchins are venomous, and hence it’s a good habit not to pick up any of them. The venom may be delivered by the spines or tiny stalk-like structures with biting jaws called “pedicellariae”.

Like other echinoderms, sea urchins generally have a five-part body plan with radial symmetry (i.e. pentaradial symmetry), at least in some stage of life. In other words, you can divide a sea urchin into 5 equal parts. Also, they are able to regenerate lost body parts – such as spines lost to predators. Echinoderms are brainless, but despite that, they can still perform their daily functions – they can move, they can eat, they can shit, and they can reproduce – all these without a brain! Also, instead of blood vessels, echinoderms have a water vascular system. This system is essentially a network of water-filled vessels used for internal transportation of oxygen, food and waste.

Salmacis

The mouth of a sea urchin is on its underside, comprising five elongated vertical jaws held together in a structure known as the Aristotle’s lantern. Sea urchins generally feed on algae and seagrasses, though some may scavenge. The anus is on the top side.

There are two main groups of sea urchins: the regular sea urchins with spherical tests; and irregular sea urchins with more flattened tests that are bilaterally symmetrical. The former generally lacks the Aristotle’s lantern as well. Interestingly, the regular sea urchins are usually found in seagrass meadows and coral reefs, while the irregular sea urchins are typically burrowers in sandy substrates. In Singapore, more than 20 species of sea urchins have been recorded.

If you step on one of these animals, be sure to have along our Sea Urchin First Aid Kit..it’s not just hot wax any more..Our kit has everything you need to provide first aid for an urchin wound..

Can Sea Urchins see you???

Researchers have known for a long time that sea urchins respond to abrupt changes in light. But they’ve been unsure about how they do it, because there are no structures that even remotely resemble eyes.

In 2009, though, researchers discovered that urchins have the same genes as those found in the retinas of humans and other creatures. The retina is the part of the eye that perceives light.

And two years later, they found bundles of light-sensitive structures on the bases and tips of their tube feet. Since a sea urchin has more than a thousand of these feet, it means they could have a couple of thousand “eyes.” The urchin’s vision isn’t very sharp, though — it reacts to big objects, but not to small ones. So it’s unclear whether it forms actual images of what’s around it, or just perceives changes in light.

Of course, the sea urchin does use its feet to clamber around the bottom of the ocean. But it doesn’t use all of them at the same time. So it’s possible that it uses some to get around, and some to keep an eye out for food, shelter, and predators.

Those bristly spines may also play a role in the sea urchin’s vision. They may shade some of the “eyes” from bright light — helping turn the entire creature into one big, prickly eyeball.

If you step on one of these animals, be sure to have along OCS Sea Urchin First Aid Kit..this isn’t hot wax and a burning candle; our kit is effecitive, medically proven first aid…

Planning a trip to Florida? Check out beachhunter.net

In the early 1990’s , David McRee set out to explore the beaches in southwest Florida. Since he was unable to find an up-to-date guidebook at that time, David decided to create one. He set out, every weekend, exploring and recording his experiences until July 2005 when he self-published his guidebook and created a website, BeachHunter.net, to help promote his book.

What started out as a web site with a few pages and a handful of daily visitors has turned into hundreds of pages with more than a million visitors annually.  Beachhunter.net provides an up to date, fact based information and photography of Florida islands and beaches to help visitors to Florida plan their beach vacations and explorations.  David’s Blog the beach feature is well worth the visit…Here’s a recent post:

http://www.blogthebeach.com/2012/nature/jellyfish/photo-portuguese-man-of-war-on-new-smyrna-beach

Along the way, David has accumulated more than 500 photographs of jellyfish and jellyfish injuries, sent primarily from people trying to identify the animal species or looking for information on treatment for jellyfish sting injuries or simply reporting a jellyfish sighting along the expanse of Florida beaches.  In our book, this makes beachhunter.net an invaluable resource for any one planning to visit Florida beaches.  The sight also provides an e book download feature about beach safety that has recorded tens of thousands of visitor downloads.

David served—2007 to 2009—as the “beaches and surf expert” for VisitFlorida, Florida’s official source for travel planning so I would strongly encourage any one planning a trip to Florida to check out beachhunter.net.  You will be glad you did..

Speaking of glad you did; when you go to the beach in Florida or any where else, be sure to take along one or all of our proven effective marine sting products.  Don’t let getting stung ruin your vacation.  Available at select Walgreen’s, local surf, dive and retailers.

Fire Sea Urchin can be lethal…

Fire Sea Urchin

Fire Sea Urchin

The fire sea urchin not only has venom; it can also bite. The size of a baseball or smaller, it is still one of the deadliest creatures in the ocean. It injects its venom in two ways: its spines contain venom sacs, with the venom able to be injected directly into the wound through the spine; but it also has dozens of tiny jaws that snap shut on prey and inject the paralyzing toxin into its victim. These attractive but deadly urchins have killed humans before, and there is no antivenom.

Ocean Care Solutions is a company specializing in the development, distribution and sales of marine sting first aid kits and jellyfish sting relief spray designed to provide safe and proven effective pain relief supported by medical and marine science first aid protocols for marine envenomations. Kevin Freeman, OCS President and a dive enthusiast, immediately realized his company was in an ideal position to actively support our nation’s disabled veterans through product support and sales profit donations.

“My family has always supported our veterans in some form or another over the years since my brother first served with the 101st Airborne in Viet Nam in 1967-68. He spent 23 years in the service and retired as a Sargent Major, U.N.Command, 8th Army, Seoul, Korea so veteran’s affairs became a way of life for our family. I can think of no better way for our company to show our appreciation to disable vets than to support such an incredible organization like S.U.D.S.”.

Soldiers Undertaking Disabled Scuba (SUDS) at Walter Reed National Military Medical Center (WRNMMC) in Bethesda, MD is designed to help improve the lives of injured service members returning from Iraq & Afghanistan. By training the warriors in a challenging & rewarding activity it can help facilitate the rehabilitation process & promote mobility. Offering this venue provides the service member with a sport they can enjoy throughout their life. S.U.D.S., established in 2007, is a Charitable and educational nonprofit corporation formed for the purpose of bettering the lives of disabled veterans through participation in SCUBA diving ( SUDS is a 501 (c) 3 non-profit organization & a chapter of Disabled Sports USA ).

S.U.D.S. honors our disabled vets by sharing their passion for the sport of SCUBA diving and to enable our participants to experience the challenges, exhilaration, and sense of accomplishment and wonder that they may find in an aquatic environment. We encourage our participants to enjoy life, to share in the camaraderie that SUDS has to offer while developing a lifelong interest in diving. “Our participants can accomplish extraordinary things regardless of their disabilities and the SUDS program gives them an opportunity to prove it to themselves,” according to the SUDS mission statement.

“Our plan is pretty simple,” according to Freeman, “we will donate $1 from the on-line sale of any of our fine marine sting products this year while providing the organization with the product they need.” Freeman went on to say, “we hope to expand this program for years and eventually to retailers but for now, anything we sell from our site, we will be honored to donate to this worthy cause. I would also like to encourage any and every one to support this organization directly at http://www.suds.org whether you need our product or not. Anything helps and your support brings a great deal of joy.”
