This clip is a short segment on one of the predators featured in this program: the horse conch. It’s practically an ecosystem onto itself, as you can see in the video’s poster frame above. Barnacles, crepidula, bryozoans, and other marine creatures that affix themselves to hard surfaces settle on its shell. 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.
It kind of looks like one of those vintage ’80′s jackets adorned with mirrors and sequins- mollusk style. This horse conch’s got a little bit of everything on it, the result of an interesting reversal of roles in this seagrass bed on Bay Mouth Bar.
If you’re a regular reader of the blog, you’ll realize that we often talk about similar research questions or ideas in the context of different projects. As David mentioned in his description of the Baymouth Bar project, this overlap is usually intentional: as ecologists, we’re interested not only in the specific habitats that we study, but also in the underlying factors that affect these habitats and the valuable services that they provide to we humans.
It may appear at times that we’ve been covering a diverse array of topics, and while this is true, all of these topics are interconnected- a web of topics centered around a couple of central themes. The diagram below is the map that shows where every post-topic fits into these central themes. Even the artists, writers, and photographers we occasionally feature have their place amongst ecological processes like sedimentation and the non-consumptive effects of predators. Every post from here on out will have one of these icons on it- if you don’t know what the icon means, just click on it and you’ll be back at this figure with an explanation:
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 →
A local crustacean (hiding in a snail shell) makes a snack of epiphytic algae.
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:
