Science as Leisure

Liz Marchio

I am a trained ichthyologist interested in what gets people interested in natural history, biological sciences, and science careers. My passion is to find out what fuels curiosity for the natural world.

Biology-related serious leisure activities can impact people's interest in ecology, biology, and natural history. Do these activities promote biological understanding? If so, how does that progress and to what level does it progress to? 

If you're interested in a starting a dialogue, please feel free to contact me. If you're curious about how I got here, my story can be found on the About Me page.

Amateur Hour: Fish Drawings Desired

I'm creating an online collage of people's renderings of fish! 

So, if you have a spare few minutes:

  1. Think of fish. What do image pops into your mind?
  2. Attempt to portray that image on paper or an app (whatever works for you).
  3. Send me your fish image and...
  4. Send me any information regarding your familiarity with fish. For example, do you study them? Keep them? Fish them? Eat them? Whatever helped you think of an image of a  "fish", let me know!

Killing Animals for Decoration

Ever look at a hunter's wall and think how unnecessary that wall of death is?

That's a lot of dead animals...

That's a lot of dead animals...

Well, as gross as that may be to some people, I have an even bigger beef to talk about- people who keep dead animals in their homes and don't even know it! 

I'm talking about the Curio trade. You know, dead starfish, coral, and fish like pufferfish and seahorses! 

Googly eyes are like my favorite thing on earth, but it seems a bit disrespectful on a dead animal decoration!! 

Googly eyes are like my favorite thing on earth, but it seems a bit disrespectful on a dead animal decoration!! 

I googled "dead puffer" images and no curio puffers showed up on the first visible page. This lends support to the idea that people do not understand a dried puffer is actually a DEAD puffer. 

This is a trade that permits collectors to collect namely marine animals for decorations. It's not illegal, but it is almost completely unnecessary and definitely tricks people! I don't know how many people I've talked to or seen online that are confused when they learn a dried starfish from the $1 store at Mission Beach is actually a REAL DEAD animal! Some even try to put these DEAD ANIMALS into their AQUARIUMS!

No, you cannot stick a dead animal into your aquarium!

Not only are consumers unaware of the dead nature of these "decorations" they are fully unaware of the process of  making them dead. People who collect these animals are collecting LIVE specimens, and many times allowing them to suffocate slowly in order to keep their shape and color. How do you think a dried seahorse is in that cute seahorse shape? It's dying and molded into an attractive pose.

Avenge me, brother!

Avenge me, brother!

Other times animals, especially those with shells, are simply bleached alive. I remember I was looking for shells on one of the beaches in South Carolina and saw a man with a HUGE beautiful shell. It was a conch-type animal and it was very much still alive. He was a stranger but still openly stated, "I'm going to keep it for it's shell". RIP you poor, and probably decade-old, thing. 



So, is the killing of sea animals, especially in the face of extinction and loss, really necessary? Do you need some sea shells sitting in some sand on the toilet? Do you really need to buy your kid that googly-eyed pufferfish that they will forget about in a week?

Probably not. 

So what do you do? Well, (1) spread the word that these animals actively die for the curio trade. They aren't washing up on beaches, they are collected and systematically killed for decoration; and (2) stop buying these things. As I said in my Walmart fish post, if you don't want to promote the consumption of something, stop buying it yourself.

What could be any easier than NOT buying something?

Disclaimer: if you are purchasing shells that were collected for meat and done so appropriately, fine. And yes, there are cultures that eat and use seahorses as food or medicine. Maybe those things are fine, maybe not, but what we can do here in the States is at least stop the consumption and thus the collection of live animals only to be killed for decor. Please pass this information along!


New Aquarium Talk for 2015: "Species. What's in a Name?"

Attention Aquarium Clubs!

I am interested in producing and presenting a new aquarium club talk on species and species concepts. In this talk, I will go through aquarium fish-related information covering:

  • Taxonomy and binomial nomenclature; its importance and use (see this blog post).
  • Introduction to species concepts
  • The "Species Problem"
  • Implications for the hobby

I want to offer a new, interesting, and thought provoking talk that not only informs but also gets aquarists (marine or freshwater) interested in asking questions and thinking about a concept most people don't question.

If you are interested in hearing "Species. What's in a Name?", please pass this post on to your club's members and president or contact me directly (
