Lobster Potato Discovered by Emmetts Expeditions

Lobster Potato – What is That?

Today is all about our Lobster Potato discovery.

Welcome to What is That Wednesday –  a blog series where Emmett and I share the strange and unusual species, we come across. We study it, take a photo, research it, and share it on the blog. If or when Emmett and I learn what the species is, I will add a link to the bottom of the What is That Wednesday post so you can click through to our discovery.

Bonus points if you know what it is and leave a comment! What are bonus points for? Nothing actually. Still, you’re awesome and I will give you a shoutout in my follow up post.

Discovering the Lobster Potato

Do you like my headline: “Lobster Potato?. The name probably makes this post sound too news worthy. Emmett and I were walking on Beverly Beach in Florida during low tide, collecting seashells and such, when we came across something strange. At first glance it looked like a lobster had been washed up on the beach. As we got closer I didn’t know what to think. I’m fairly certain it was not an animal. Unless it is similar to coral (more on coral in another post).

Observing the Lobster Potato

Next onto the description of the lobster potato. The subject is mostly red with purple and orange tints. It had many branches – for lack of a better word – and fuzzy hairs coating the surface. Brownish-black stick-like objects protrude out sporadically on those colored branches as well. When using a shell against it’s exterior, the skin peeled away very thinly. The center was hard and white. Much like a potato.

Our Hypothesis

Finally, while I imagine it to be some sort of sea root (if that is a thing, I’m not sure yet), Emmett is convinced it is a mutated cooked spiny lobster with a dead worm and two rotten apples fused to it.

    Not sure… but it does remind me a little of galangal though it doesn’t exactly fit that classification either and being washed up on the beach doesn’t fit with galangal either! But perhaps some kind of ocean rhizome related to the ginger/galangal family?

      Hello Elizabeth,
      Thanks so much for sharing about the galangal! It does look an awful lot like one. Emmett and I will start researching and see if we can find one like this. It’s possible this “root” did not grow in the ocean. It may have been lost in the ocean before washing back up on the beach.
      If we find a match I’ll be sure to give you a shout out in my follow-up post 🙂
      Thanks again,

what do you think?
