Sea Urchin has no followers yet. Be the first one to follow.
In the 1960s and 1970s Sea Urchins became so abundant that they destroyed Kelp beds and other forms of algae and formed urchin barrens that leave very low biodiversity in their wake. Scuba Divers and the California Department of Fish and Game endorsed hammering and Quick liming Urchins to reduce their abundances in order to restore habitat. This historical footage shows the hammering of Sea Urchins in Southern California by diver clubs. PURP- Palos Verdes Underwater Restoration Project. Urchins are often referred to as a "pest" or "nuisance" species because of the damage and ensuing dis-equiblirium that they can cause when they over proliferate.

The "i-morley" studio is preparing a live broadcast in the studio. There is a large analog synthesizer alongside digital equipment here. Also, a Japanese style dinner is being prepared, featuring fresh sea urchin and a mushroom "nabe". "Sea Urchin Shepherd" is a team effort to divert the Korean government from culling wild sea urchins in its waters on a massive scale. We want to persuade the international market that sea urchins taste great, and that they are worthy of a regular place in the daily diet. For more information on Sea Urchin Shepherd, see this video: www.youtube.com
In a recent TV interview at the Blue Ribbon Task Force meeting in Long Beach,Ca., Charlotte Stevenson, a scientist for the Heal the Bay org. in Santa Monica, candidly statedWeve done it on land, now its the waters turn. This referring to the Marine Life Protection Act established in 1999.They are trying to tell you that if you leave the ocean alone, it will heal itself. This is unfortunately not true. Let us look at a quick comparison of the California Coniferous Forest and the Kelp Forest. The trees are infested with a devastating bug named the Western Pine Beetle (Dendroctonus brevicomis). It destroys large areas of coniferous trees. The outbreaks are believed to be spurred on by the lack of predators, namely the Three Toed Woodpecker (Picoides arcticus). Left unattended, this bug can and has destroyed forests. The Kelp forest is infested with a bug named the Red Sea Urchin (Strongylocentrotus franciscanus).This bug destroys large areas of Kelp Forest. These outbreaks or \"Urchin Barrens\" are spurred on by the lack of predators and if left unattended will and ARE destroying the Kelp Beds off the California coast. If we leave it to the current MPAs outline, there will be nothing to keep these bugs from devastating the bio-diversity necessary for a healthy ocean. We need to establish a case by case study for each fishery and each area proposed in this Act. The trees and kelp are each a necessary host to a bio-diverse ecosystem.
This is a movie of sea urchin egg fertilization (species: Lytechinus variegatus). Note that you can see the sperm fertilizing each egg, including both the head and the tail. Also note the formation of a fertilization cone around the sperm after initial contact with the egg. Sperm binding initiates a series of intracellular signaling events that result in the elevation of the fertilization envelope (clear membrane surrounding the fertilized egg). The fertilization envelope prevents the egg from being fertilized by more than one sperm (a fatal event) and protects the developing embryo during early development. It takes about 1-2 minutes for the fertilization envelope to rise completely after sperm binding.
AAtheory.com presents its web-series, "Weird Asian Eats." Founder, Ellie and friends go around to Asian restaurants to try some of the strangest foods to get in touch with their Asian side. In this episode, the crew find themselves at a Japanese sushi restaurant eating sea urchin sushi, which is the gonads of a sea urchin. Watch the hilarity ensue in the first installment of "Weird Asian Eats."

Off the Californian coast, giant kelp grow to gigantic sizes. They provide a good source of food to armies of industrious sea urchins, which attack them in force in a seemingly unending chase of life seeking food
Soon after fertilization, we watch as two new sea urchin zygotes divide (mitosis) through eight cycles of synchronized division right up to the point of gastrulation. One can see the nuclei as dark spots in the 'green' cytoplasm. Scale bars and times are included, along with some strange sounds recorded in the deep. Imaged via dark-field microscopy. I apologize for the shaking in the middle - we had to add more sea water to prevent the slide from drying out.
