| Sea urchin Egg SEM 1030X |
| Sunday, July 31, 2005 |
This is an image from work. What you see here is a sea urchin egg, but just the egg (never met a sperm so to speak). The big grid it is on is really very fine mesh, four times as small as a window screen would be.
It is a pretty funny story, but when you mate urchins in the lab, you have to stimulate them into producing the sperm and eggs. You do this by injecting them with a small amount of, basically, salt water. And this puts them in the mood, as it were, and in a few min. you get either orange or milky ppt. And the rest is history. In a few min, the microscopic stork comes and you have a developing sea urchin embryo. |

This is so strange, I had sushi last night but have never been adventurous enough to order sea urchin.
I keep imagining a drowned Victorian child.

Hey Alex, thanks for your comment on my blog!
I love sea urchin sushi, in fact it's one of my favorite types, and never once (until now) stopped to think about how their procreation worked (in lab or otherwise), lol.

Yeah I also like uni. It is expensive, but once a year I get uni at a really good place with a raw quale egg on top.
A side of Oshinko... And thats what sushi is about I think.

Hi Alex! In Buzios, Brazil, I used to dive with friends to catch sea urchins and eat them alive with lime and black pepper, on the boat. They're wonderful. best, Jorge

Will the salt water thing work with human females? You know, now that I think of it, being near the beach does cause some women to act mighty unusual...hmmmmm

Yeah, stabbing women in the abdomen with a needle of salt water will make them ovulate.
Frankly im shocked you didnt already know this.

Well, whatever floats their boat, I guess! LOL

Hola, Alex! gracias por visitar mi blog.
En mi universidad todos los años se hace una práctica de fecundación de erizos, pero como vivimos a 400 km del mar mediterráneo muchas veces llegan muertos y el profesor tiene que volver a por ellos! Por lo demás es un fenómeno fascinante, y se puede ver con un sencillo microscopio.
