Magnetic Island!

G'Day Mates,

There's an island off the coast of Australia named Magnetic Island. I went there yesterday to collect some samples of seaweed (macroalgae). I collected 5 different samples of seaweed, with the help of my snorkeling skills, and brought them back to the lab.

At the lab I shook the samples of seaweed in water and placed that water in a filter. The material left over are thousands and thousands of little cells that live on the seaweed. We analyze these cells (microorganisms) to see if any of them can be harmful to certain fish. Some of these cells release deadly toxins into fish.

After we collected the cells off of the seaweed we placed the seaweed on a piece of paper and created a herbarium (see picture).

Next we used a key to identify the species of seaweed that we collected. Pretty cool stuff.
Ok now for the question. Remember first to answer this question wins a prize. Who named the island "Magnetic Island?"
