Green Sea Urchin Fact Sheet

Green Sea Urchin Fact Sheet With its sharp-looking spines, the green sea urchin may look frightful, but to us, it is mostly harmless. Sea urchins arent poisonous, although you might get poked by a spine if youre not careful. In fact, green sea urchins can even be eaten. Here you can learn some facts about this common marine invertebrate. Sea Urchin Identification Green sea urchins can grow to about 3 across, and 1.5 high. They are covered in thin, short spines. The sea urchins mouth (called Aristotles lantern) is located on its underside, and its anus is on its top side, in a spot that is not covered with spines. Despite their immobile appearance, sea urchins can move relatively quickly, like a sea star, using their long, thin water-filled tube feet and suction. Where to Find Sea Urchins If youre tide pooling, you might find sea urchins underneath rocks. Look closely - sea urchins may camouflage themselves by attaching algae, rocks, and detritus to their spines. Classification Kingdom: AnimaliaPhylum: EchinodermataClass: Echinoidea Order: CamarodontaFamily: StrongylocentrotidaeGenus: StronglyocentrotusSpecies: droebachiensis Feeding Sea urchins feed on algae, scraping it off of rocks with their mouth, which is made up of 5 teeth collectively called Aristotles lantern. In addition to his work and writings on philosophy, Aristotle wrote about science, and sea urchins - he described the sea urchins teeth by saying they resembled a lantern made of horn that had 5 sides. Thus the urchins teeth came to be known as Aristotles lantern. Habitat and Distribution Green sea urchins are found in tide pools, kelp beds, and on rocky ocean bottoms, to areas as deep as 3,800 feet. Reproduction Green sea urchins have separate sexes, although it is difficult to tell males and females apart. They reproduce by releasing gametes (sperm and eggs) into the water, where fertilization takes place. A larva forms and lives in the plankton for up to several months before it settles on the sea floor and eventually turns into an adult form. Conservation and Human Uses Sea urchin roe (eggs), called uni in Japan, are considered a delicacy. Maine fishermen became huge suppliers of green sea urchins in the 1980s and 1990s, when the ability to fly urchins overnight to Japan opened an international market for urchins, creating a Green Gold Rush, in which millions of pounds of urchins were harvested for their roe. Overharvesting amid a lack of regulation caused the urchin population to bust. Regulations now prevent overharvesting of urchins, but populations have been slow to recover. The lack of grazing urchins has caused kelp and algae beds to flourish, which in turn has increased crab populations. Crabs love to eat baby urchins, which has contributed to the lack of recovery of urchin populations. Sources Clark, Jeff. 2008. After the Gold Rush (Online) Downeast Magazine.

Ashley Flores missingIt only takes 2 seconds to forward this.If it was your child, you would want all the help you could get. Analysis: This is a hoax, circulating since May 2006. Neither the Philadelphia Police Department nor the National Center for Missing Exploited Children lists (or has ever listed) a missing child by the name of Ashley Flores. No Amber Alert has ever been issued in her name. Moreover, the viral message contains none of the critical details one would expect to find in a real alert for example, a physical description of the missing person, the time and place of disappearance and contact information. Another giveaway is the presence in the body of the message of several sentences copied word-for-word from previous missing child hoaxes (see Penny Brown and C.J. Mineo). The Ashley Flores / MySpace Connection Though she never really went missing, it appears that Ashley Flores does exist and lived in Philadelphia when these alerts first started going around. By following hyperlinks embedded in a version posted on MySpace.com, I found an exact match (long since deleted) for the image above in a photo gallery on Photobucket.com, along with several others (long since deleted) that were uploaded by the same user and featured a young woman named Ashley who bore more than a passing resemblance to the girl pictured above. The images were posted by someone using the screen name Vixter609, whom I found blogging under the same alias on MySpace.com with her given name listed as Vicki, her age as 17 and her city of residence as Philadelphia. When I contacted Vicki to ask what, if anything, she knew about Ashley Flores and her status as a missing person, I received the following reply (reproduced verbatim): ashley flores is not missing it was a merly a joke that got completely out of hand please imform everyone that e-mail that she is NOT missing it was a joke im sorry about any confusion Subsequent inquiries went unanswered. That this little joke caused confusion is putting it mildly. 2009 Update After a version of the Ashley Flores email containing the contact info of the Rolla, Missouri police department circulated in 2009, said police department was forced to change its telephone number because it was receiving up to 75 calls per day on the matter. The citys online FAQ page still contains a reference to the hoax. The Flores alert is listed on the U.S. Department of Justice Amber Alert website as a known hoax.
