10 Tasty Fish You Don't Want to Eat

The Monterey Bay Aquarium Seafood Watch offers a list of fish you can enjoy and those you can't. Many on the list you may or may not enjoy depending on where and how they're caught. However, there are some you just don't want to touch. Check out 10 of these tasty fish that you want to let swim in peace.

The Freshwater Eel
It is better known as Unagi among the sushi lovers, where you can see it draped over the top of a tasty roll covered in a sweet sauce. However, while tempting, you'll want to skip ordering a roll that features Freshwater Eel. Young eel are caught in the wild and raised on farms, and significantly decreasing the number of young animals in a wild population has sent the species into decline. Not only that, but the method of farming eels pollutes the surrounding areas. This is one sushi option you always want to avoid, but there are sustainable options. (crap, unagi rolls are my very favourite...!)

Salmon
It is known to have some great health benefits and is a wonderful option but only if you're ordering wild Alaskan. You never want to indulge in farmed Salmon. No matter what your restaurant server says about the farming practices, if they don't simply say "It's wild Alaskan," don't order it. Farming salmon, as with farming eel, causes pollution in the surrounding environments due to waste and parasites leaking out into the waters next to the farms. Plus, the feeding methods are less than desirable, using fish stocks that put pressure on wild populations or corn, which leads to a paler meat that is then died the pink color consumers recognize. Until more sustainable farming practices are developed, farmed Salmon is on the No list.

So You Think You Know? : Wildlife

To switch from male to female and back again without the help of surgery is a feat that only a handful of organisms can accomplish, including some types of fish, shrimp, snails and worms. Now, a new study adds mushroom corals to the list.

It is the first study to show that any coral can change sex in either direction, let alone both.

Understanding why and when some corals make the switch may eventually help scientists protect them from the stresses of a changing environment. For now, the study remains a fascinating window into the biology and evolution of these corals.

Mushroom corals belong to a family called Fungiidae. They are solitary, mobile species that live throughout the Pacific and Indian Oceans. Mushroom corals are abundant and diverse, but how they reproduce is something scientists haven't known much about.

The transition from male to female seems to be a natural progression with growth, van Woesik added. But the fact that the corals sometimes switch back from female to male, might be a sign that they are in distress and need to conserve resources.

The oceans face a lot of stressors these days, from pollution to climate change. If environmental pressures push too many mushroom corals towards maleness, a skewed sex ratio could threaten their future.

Told You We Look Like Animals!

This “Napolean Dynamite” guy here is one weird-looking dude.

Tina Turner got a lot of attention for her legs and ability to perform. She deserves some attention for how much she looks like a chow, too.

Both Black and the dog look like they walk around on their face.

Ever notice how Josh Hartnett has those weird, stoned eyes that dogs always have too?

Aww look, they both have little vests. And they probably both spend a lot of times just shivering.

No more comment needed.

Gay Ducks Give an Extinction to Their Own Species

Keepers at a bird sanctuary in West Sussex hoped that the last remaining female Blue Duck in the country - called Cherry - might mate with either of the drakes, Ben or Jerry.

But neither male duck appeared interested and are now inseparable at the Arundel Wetland Centre, leaving Cherry to her own devices.

Centre warden Paul Stevens said he was disappointed that efforts to produce new Blue Duck offspring had failed but said the two male birds made "a lovely couple".

"They stay together all the time, parading up and down their enclosure and whistling to each other as a male might do with a female he wants to mate with," he said.

"People who visit the centre think they're a fantastic couple, without really coming around to the idea that they are two males.

"They both have very big personalities and people come from all over the country to come and see them.

Cherry doesn't seem bothered by it, she's just happy to keep herself to herself."

Blue ducks originate from New Zealand but there were thought to be just three birds in the UK.

Keepers initially introduced Ben to Cherry, but neither seemed keen. They then brought Jerry down from a sanctuary in London.

Mr Stevens said: "Cherry showed some interest in him. She displayed typical mating behaviour - she approached him and called to him, she even looked like she was nesting.

"We thought it was great and it was all going to happen but nothing ever did."

Mr Stevens said the male ducks were then placed in the same enclosure: "To our surprise the two males really took to each other and it was obvious that they really liked each other.

"It would have been nice to get a last clutch of eggs from Cherry but Ben and Jerry do make a lovely couple."

So You Think You Know? : Wildlife

Check out the fish Macropinna microstoma. It has tubular eyes and a see-through head.


The common name for the fish is "barreleyes." Monterey Bay Aquarium Research Institute investigators recently figured out why this species has such an unusual head. Its eyes can actually rotate within its "skull," so the transparency allows the wary swimmer to keep a literal eye on happenings above it, as well as to the sides and directly in front.
