The Blobfish


Yesterday, The Ugly Animal Preservation Society voted the blob fish the ugliest animal in the world. In honor of the blobfish, I'm reposting this blog from a little over a year ago.

Today, the Smithsonian came up with a rebuttal, In Defense of the Blobfish. The article includes a picture of what the blobfish would look like if we saw it swimming, supported by the ocean's buoyancy. Be sure to take a look if you'd like to see the blobfish in its full and true glory!

From June 2012: My Tribute to the Blobfish

If you've seen "Men in Black 3" the animal in this picture should look familiar. It's a blobfish. Yes, there really is a fish that looks exactly like Jimmy Durante swimming around, or more accurately, floating around, in the ocean.

The blobfish only grows to about 12" in length. It lives 2,000-3,000 feet below the ocean surface in the waters south east of Australia. That's the same depth that fishermen have to go to catch lobster, crabs, and some of our other favorite seafood that we've fished out from shallower waters. The blobfish has no commercial value: it's inedible.

Blobby has no way to escape the fishing nets because, just like he(she?) looks, he's basically a glob of Jell-O. His body is buoyant and he floats in the water column at a depth of about 800m. He doesn't need muscles or oxygen to swim because he doesn't have to swim.

According to Dr. Callum Roberts, one of the world's most respected experts on marine conservation, the blobfish is in danger of becoming extinct because of overfishing: "The Australian and New Zealand deep trawling fishing fleets are some of the most active in the world so if you are a blobfish then it is not a good place to be."

It's sad that, to satisfy our demand for seafood, we're willing to eliminate animals that most people don't even know about. This isn't a case of "people are starving so we have to do this to feed them." These are high-end seafood products going to feed people who all ready have too much protein in their diets. It's even sadder to think, given the vast ocean, that we're unwilling to protect even small areas of it to ensure ocean resources are around for future generations.

Those grumbling loudest about "traditional values" might want to remember back to the day when saving was a prized value. People delayed gratification, foregoing something now for something better in the future. I hold little hope that the marine environment will improve in the future--not with a world population of 7 billion and growing--but maybe by saving some of it now, we can at least have something left for the future.

If you're worried about the blobfish, or any other animal we might be destroying with poor fishing practices, here are some things you can do:

  • Before you order that lobster, crab, or other seafood item on the menu, find out where it's from. Only order, buy, eat sustainably harvested seafood. http://www.nrdc.org/oceans/seafoodguide/
  • Eat lower on the food chain.
  • Support the establishment and management of marine protected areas.
  • Use birth control. (Seriously. Don't you think 7 billion people on the planet is a little ridiculous? You don't really need more than replacement children, i.e. 2 kids per couple?)

Jellyfish Lovers' Paradise!

Thanks to a Facebook post by my friend Dave Jenkins from Down Under, I've discovered a dream destination for jellyfish lovers, like myself! Jellyfish Lake in Palau is a marine lake on the island of Eil Malk. The lake is connected to the ocean by fissures and tunnels through the limestone from reefs that built the island.

Photo from To-Travelling - visit their website for more on the
lake and other fun things to do and see in Palau.


Not only is Jellyfish Lake a cnidarian-lovers' dream, but a chemical oceanographers' fantasy playground, too! The lake is stratified into oxygenated and anoxic layers, the deeper layer, devoid of oxygen, is also a toxic pool of hydrogen sulfide, ammonia, and phosphate due to a combination of conditions that prevent mixing of the two layers.

From Wikipedia


Wait! There's more! This is also a playground of fun discoveries for marine microbiologists: the first three meters of the anoxic zone is laden with bacteria, including at least one species of a purple photosynthetic sulfur bacterium. The bacterial population is so dense that this layer absorbs all sunlight so the anoxic layer below the bacterial plate is pitch dark, but transparent. Sadly, the hydrogen sulfide can be absorbed through a person's skin--and kill them--so you and I won't be able to dive down and see that for ourselves. SCUBA diving isn't allowed in the lake, only snorkeling, in an effort to keep tourists from dying.

Want to see what it looks like to swim through a lake filled with jellies? Click here to watch a YouTube video of the experience. While the video caption says these guys are non-stinging, that's not quite accurate. The golden jellies do sting, but their nematocysts have little effect on humans. We  hardly notice them unless you're allergic, in which case, you'll know they sting!

I've added yet another destination to my always-growing list of places to visit. Other people have bucket-lists of things to do before they die, my list is a travel itinerary. So many fabulous places left for me to explore. Finding one that is the ideal destination for a biogeochemistry loving island girl, well, that's the epitome of "must-see" places. Thanks for sharing, Dave!
