Q: What is Sargassum?
A: Sargassum is a brown algae which floats (due to attached gas bladders) in large mats that will cover miles of ocean. These huge expanses of algae are a unique habitat which is inhabited by many types of juvenile fishes and invertebrates. Some fish, like the Sargassum fish, spend their entire lives with this algae.
We learn about this habitat by collecting Sargassum in a small mesh frame which is pulled through the top of the water column.
