Ask Aly: Ecosystems and Escape Artists

You asked and Aly answered!

On behalf of blogopus, I’d like to welcome back guest blogger Aly Busse, the very busy director of school and public programs at Mote Marine Laboratory in Sarasota, Florida. Aly jets by to answer readers’ questions about our favorite cephalopod in periodic Ask Aly postings, so keep them rolling in!

I realize this is a question that may be a bit much for a blog Q&A, but I was wondering if there’s anything that can be done, at this point, to protect the ocean’s ecosystem or help it bounce back before more damage is done?

Aly: This is a big question, but I think it is an incredibly important one! It is very easy to see what is happening in our oceans and on our planet and think the problems are too many and too big and it is too late. The honest answer is that no one really knows for sure if we’ve reached a tipping point.

However, personally, I believe that it is absolutely not too late and many, many scientists and researchers who are much smarter than me agree. The oceans are an incredibly resilient system and can heal if we let them. There are great success stories about damaged areas rebounding once they have been protected. We are in a critical time now, though, for sure. If we don’t all make these changes, at some point it will be too late.

I think being informed about how your actions impact the ocean (and land—it is all connected!) is essential to making needed changes. Simple things like using your powerful consumer dollars to support companies and products that use recycled or reduced packaging or green practices (and even writing to those that don’t!), choosing seafood that is sustainably caught or farmed—a great resource for this is the Seafood Watch Seafood Recommendations from the Monterey Bay Aquarium—and supporting conservation, research, and education efforts.  Those are some small actions and changes that create a big impact.

Can you have an octopus as a pet?

Aly:  The short answer is yes. However, these animals are quite a bit of work to keep happy and healthy. You wouldn’t just be able to plop one in a fishbowl and feed him some flake food like a goldfish!

First of all, they are incredibly intelligent animals. Octopuses are notorious for being escape artists! As long as their beak fits, they will break out through the smallest of holes. Here is one of my favorite videos demonstrating this:

 
As for diet, octopuses are very demanding! They need to eat fresh fish, shrimp, crabs, and other pricey seafood—so frequent trips to the fish market would be part of life with a pet octopus.

Octopuses also are not very social and don’t get along with most other creatures (including other octopuses), and would simply eat many other common aquarium animals. You may notice during an aquarium visit that an octopus is put in a tank all alone with lots of rocks and hiding places. In the ocean, they are solitary animals and prefer to be by themselves, hiding under rocks and among the corals.

Octopuses are also very picky about the water they live in—it has to be the perfect temperature, have a precise mixture of nutrients and chemicals in it, and must be tested very often.

Finally, as with any purchase of an animal, you need to make sure you know what exact species it is, where it came from, and if it is in good health before making the decision to buy it!

    Ask Aly

    You asked and Aly answered!

    We welcome back our first guest blogger: Aly Busse, director of school and public programs at Mote Marine Laboratory in Sarasota, Florida. Aly will jet by once or twice a month to answer readers’ questions about our favorite cephalopod, so keep them rolling in.

    What is a cephalopod anyway?

    Aly: In organizing living things, scientists use a system of classification to make sense of how everything relates to one another. It is organized from big groups (kingdoms) all the way down to each particular type of animal (genus and species). Cephalopod is the name of the Class that all octopuses are put in, along with squid, cuttlefish, and nautilus. It translates from the Greek to mean “head foot.” Don’t you think that is a perfect name for these animals?

    The best part of this system is that if you discover a new organism, you get to choose the name yourself, although not after yourself—that is not allowed! Here is a great article about some really creative species naming: “What Goes into Naming a New Species? A Lot” (there is even one named after a certain Star Wars villain!).

    This scientific classification isn’t finalized by any means and it changes all of the time as new critters are discovered and scientists learn more about them. For example, when I was in school I learned there were five Kingdoms of living things. Now there are six!

    I really like science and I really like organization, so, of course, I love scientific classification and could go on about it for way too long!

    I know that an octopus has three hearts. Can an octopus survive if one heart is injured, defective, or dies?

    Aly: This is really interesting question. Let’s back up and think about why octopuses have three hearts. They do have three hearts, but it isn’t like they have one main heart and two back-up hearts!

    Our one human heart does several things as it beats—it pumps blood to the lungs, where it gets rid of carbon dioxide (which we eventually exhale) and picks up oxygen (which we get from breathing in). It then distributes the freshly oxygenated blood to the rest of the body. Getting blood to the lungs is critical, since this is where it makes the exchange from waste (carbon dioxide) to good new stuff (oxygen). Two of the four chambers in the human heart do just this—make sure the blood gets to the lungs.

    Now, do octopuses need oxygen like humans? The answer is yes—but they get it from the water instead of air. So, octopus circulation is set up differently. An octopus has one main heart, called the systemic heart, and two smaller hearts near its gills. The two smaller hearts pump blood to the gills, where they dump waste and load up on the good stuff, and then pump the oxygen-rich blood back to the main heart. The main heart then pumps this blood around the body. Each heart is crucial to maintaining the strong blood pressure that allows octopuses to be so active.

    So, do you think an octopus could live without one of its hearts now that you know what each one does?  Probably not, but just like with humans, sometimes amazing things happen!

      Meet Aly Busse, Our First Guest Blogger

      On behalf of blogopus, I’d like to welcome Aly Busse, our first guest blogger. Aly will answer our readers’ octopus questions in bi-monthly Ask Aly postings.

      I’d also like take this opportunity to thank Lauren Markham, who has done so much to help establish this blog on so many fronts that she might as well have eight arms. Most of her work lies deep within our depths, so I want to acknowledge her efforts. We receive wonderful feedback about her art and photographs, which complement and often inspire the daily postings. Thank you, Lauren!

      Blogopus is just a hatchling (Aly, is this the correct term for a baby octopus?), a work in progress. I look forward to sharing this journey as it unfolds. Thank you for returning to read—and for helping to make The Octopus Garden grow!

      Lauren recently sat down to videochat with Aly. Here’s the interview. Check back later this week for the inaugural installment of Ask Aly!

      Author’s Note: I recently had the pleasure of interviewing for blogopus my friend of over fifteen years, Aly Busse. While I’ve known since we were teenagers that Aly had a love of the ocean, it wasn’t until this conversation that I realized the “depths” of her passion. She is excited to be a part of blogopus as a guest blogger and looks forward to answering all of your questions!

      Aly graduated from the University of North Carolina Wilmington, with a bachelor’s of science in marine biology. She also holds a master’s in secondary science education from Old Dominion University. She is currently the director of school and public programs at Mote Marine Laboratory in Sarasota, Florida. Aly previously served as the senior program coordinator (Outreach) at Rutgers Museum, and was the associate director of the Rutgers Geology Museum. She brings a wealth of knowledge to the blogopus community.

      LM: When did you first realize you wanted to study marine biology?

      AB: My love for the beach developed early on during frequent visits to the Jersey Shore with my family and to South Carolina with my Grandma. When I found I could translate my love of the ocean into a career, I thought, why not?

      LM: Tell me about your work as director of school and public programs at Mote Marine.

      AB: I work with scientists to bring their current research findings to the public, in particular to children and their families. As part of my job, I seek out opportunities for expanding our impact in the community and beyond.

      We recently began working with SciGirls [a weekly public broadcast television series and educational outreach program for elementary and middle-school children based on proven best practices for science, technology, engineering and math education for girls designed to encourage girls to pursue STEM careers], a program I’m happy to be a part of.

      We also have a trip coming up in 2012 that will be amazing. I will be traveling with a Mote scientist to South Africa, where the focus will be on human interaction with sharks. This trip is open to the public and we will be offering more like this in the future. The point of these trips is to let people know what’s happening in the research world.

      LM: What is the best part about working at Mote?

      AB: The best part is working at an institution that has such a strong history and culture of discovery that is research-focused. The best perks include kayaking, snorkeling, and collecting critters in the water with kids as part of our outreach program.

      LM: What is your favorite aquatic animal and why?

      AB: Coral. It comes in so many varied shapes and colors. They all live together in colonies and those colonies form whole ecosystems in the coral reefs. They support a lot of other animals.

      LM: I have a couple of octopus questions for you. Are they found everywhere?

      AB: Not everywhere, for example, not in fresh water or in very cold water. They lack shells and so are in need of extra protection. They are found mostly in tropical and temperate waters.

      LM: Okay, is it octopi or octopuses? Also, I sometimes hear “fishes.” What is that all about?

      AB: It is “octopuses.” It is a common question and often the subject of debate.

      When we refer to “fishes” in the science world, we are speaking of different species of fish altogether. If we are referencing one type of species, we use “fish”—whether there are one or one-hundred.

      [Author’s Note: I found this video helpful: Merriam-Webster Ask the Editor—Octopus.]

      LM: Are you excited for blogopus readers’ questions?

      AB: I am! I love talking about marine animals and I love when people are interested in the ocean.

      LM: Where can we learn more about marine biology and the ocean?

      AB: One of my favorite science blogs is Southern Fried Science. The Smithsonian’s National Museum of Natural History’s Ocean Portal has lots of information and is a great resource. And of course, I spend hours just scrolling through the photos on the National Geographic website.
