In the video you’ll see its bright orange body as it roams the seagrass beds of the Forgotten Coast. And you’ll see it eat another large predatory snail, the lightning whelk.
A listing of the animals seen in the slideshow is at the end of this post.
March is Seagrass Awareness Month, so it seems a fitting time to share some photos we took last fall. Seagrass beds are an under-appreciated habitat; they’re very productive and are more important than meets the eye (here I admit that neither seagrass beds or salt marshes seemed all that interesting to me until I actually went into them and took a closer look). Here are a few quick facts: Continue reading →

Most of my blog posts have revolved around my research in salt marsh habitats, with mention of seagrasses only in the context of their role as wrack in the salt marsh. However, I’m also interested specifically in seagrasses and the community of animals that they support, and particularly in understanding why seagrasses are experiencing declines in so many regions of the world. First, a little background on the plants themselves:
