ANDIE
ok so heres a little "about me" for all of my enthralled viewers Hobbies: art (all sorts), tennis (yes im planing on playing on the calverton team this year), Horseback riding (it is a sport for all you non believers out there), and Im really into music mainly Rock and Alternative. So I like most normal people like to laugh so heres a video that cracks me up every time, it's a song by OK GO so here: hmmm.... not sure if that uploaded correctly All right, now is the part when i tell you about my favorite part of Bio Class!!! fun stuff i knowBut really, the labs that we do are great. Lots of fun, just yesterday we did a lab on the effectiveness of cell shape/size. We used red agar cubes and we cut shapes out of them to see what would work best. After we got a shape we were happy with we put it in vinegar and then you waited for it to turn all yellow. We also have "class pets" which I think is awesome. We have two snakes (they are yet to be named!!!), Madagascar hissing cockroaches (many, im not positive how many though), and we also have a tarantula.

The Flagellum:
function: locomotion
Description: a whip like structure that protrudes from the cell(flagellum actually comes from the Latin root word for whip)
Structure: it has a core of 9 microtubules fused together

Im an avid snorkeler, and many times snorkeling I've seen a big spiny starfish, so I decided to find out what exactly it was. Turns out that starfish aren't really fish at all, there echinoderms. Now echinoderms is a big word so here's the definition for you: "Any of numerous radially symmetrical marine invertebrates of the phylum Echinodermata, which includes the starfishes, sea urchins, and sea cucumbers, having an internal calcareous skeleton and often covered with spines." The starfish that I was seeing the most of was called __the Cushion Starfish__.
They're generally found between South Carolina and Florida, and their ideal home is on coral reefs and rocks on the bottom of the sea floor. A cool thing about starfish is that if they loose a limb they can regenerate it. Also, they can generate a totally new starfish from a severed limb. However, thats not how they reproduce. To reproduce males and females release sperm and eggs into the water to be fertilized. When an egg is fertilized it sinks to the sea floor to develop.
Another really cool thing about starfish is the way they eat. They're carnivores, and their favorites include oysters, clams and sponges. So, when they eat their stomach comes out of their body and surrounds the unfortunate animal they fancy for lunch. Digestive juices start to eat at the prey till it's dissolved enough so the starfish can absorb it, then the starfish sucks back in its stomach. Yummy.

Here's some other starfish I've seen out and about, can you tell what species they are?
(There happens to be over 2,000 different species of starfish by the way, so good luck!)

Ian-approved this post, he thought it was informative, and interesting because he had never heard of the Cushion Star Fish and he learned about echinoderms

Jordan-This post is very interesting. To have your stomach come out of your body to eat food is amazing. It reminds me of the ball park franks commercial where the arm comes out of the guys stomach. Great Job Andie, I approve this post.

.edu and .gov
I can have my sources evaluated by my peers
I will properly site sources that i use in posts and comments
I sighted my sourced correctly in my Starfish post (above this chart) and in my comments on Sky's "Determine a Horses Age By its Teeth" post

I critiqued sources on the Credible sources page to help my peers use reliable sites
All my sources for my post were approved by peers
http://missbakersbiologyclasswiki.wikispaces.com/Credible Sources
