2 Odd Things I Just Learned About Fish

When I'm not blogging for mental_floss, I can usually be found wearing bright orange rubber pants and gutting, cutting and selling fish at the local Whole Foods. Sometimes, these two worlds collide and I find some scientific research involving my finned friends that needs blogging about. Recently I learned two things about fish that may seem like throwaway trivia at first, but provide us with some useful information once you get past the "gee-whiz" stage. (Note: That's not me in the photo. But it is Charlize Theron. Picture courtesy of Hollywood Back Wash.)

1. Odd thing I learned #1:
Vulnerability to being caught by fishermen is a heritable trait in largemouth bass

After tracking catches during four years of experimental fishing, researchers at the University of Illinois segregated largemouth bass in a lake into groups of high and low vulnerability (HV and LV groups, respectively) to being caught. The offspring of these two groups were reared, tracked and segregated into HV and LV groups. Their offspring, the third generation of fish in the experiment, went through the same process (there's a slightly more detailed explanation of the study at my website). The researchers recently published the results of the 20-year experiment* and conclude that, one, vulnerability to being caught by fishermen is a heritable trait in the bass, and two, recreational fishing can cause evolutionary changes the same way commercial fishing can.

The takeaway:

Male largemouth bass are single dads, staying with the eggs and guarding their offspring for the first month after they hatch (the females leave the eggs after laying them). Aggressive HV males have more success mating and are great dads, protecting their fry from predators, but they're also more likely to go after fishermen's lures, get caught and leave their offspring vulnerable to predators. The combination of the bass' reproductive strategies and the pressure of recreational fishing during spawning season may affect the bass' reproductive success and continuation, so the researchers recommend that wildlife management agencies create bass spawning sanctuaries and limit or restrict bass fishing during spawning season.

Odd thing I learned #2:
Fish get seasick

German zoologist Reinhold Hilbig put an aquarium containing 49 fish on a plane, which, during its flight, went into a steep dive to simulating the loss of gravity. Eight of the fish began turning around in circles, and exhibited other signs of having lost their orientation and sense of balance. Hilbig told the Telegraph that the fish behaved "like humans who get seasick," and "looked as if they were about to vomit." (What that looks like I don't know.)

The takeaway: This was an experiment on the effects of weightlessness in water as part of Hilbig's research on how humans are affected in space. The eight seasick fish were later killed and their brains were examined, revealing that many of them had asymmetric inner ears. Some fish have an inner ear system that helps them stay upright, like the inner ear balance system in humans. Asymmetric inner ears in humans, and apparently, fish, make one more susceptible to motion sickness. Hilbig hopes to use the results of the experiment to draw conclusions about how humans might react in similar situations. (That's sort of vague, I know. I wish there were more, but the news stories on this are all short on info and no amount of Googling seems to turn up the name of a paper associated with the study or even background info on Hilbig. Alas.)

13 Fascinating Facts About Nina Simone

Nina Simone, who would’ve celebrated her 85th birthday today, was known for using her musical platform to speak out. “I think women play a major part in opening the doors for better understanding around the world,” the “Strange Fruit” songstress once said. Though she chose to keep her personal life shrouded in secrecy, these facts grant VIP access into a life well-lived and the music that still lives on.

1. NINA SIMONE WAS HER STAGE NAME.

The singer was born as Eunice Waymon on February 21, 1933. But by age 21, the North Carolina native was going by a different name at her nightly Atlantic City gig: Nina Simone. She hoped that adopting a different name would keep her mother from finding out about her performances. “Nina” was her boyfriend’s nickname for her at the time. “Simone” was inspired by Simone Signoret, an actress that the singer admired.

2. SHE HAD HUMBLE BEGINNINGS.

There's a reason that much of the singer's music had gospel-like sounds. Simone—the daughter of a Methodist minister and a handyman—was raised in the church and started playing the piano by ear at age 3. She got her start in her hometown of Tryon, North Carolina, where she played gospel hymns and classical music at Old St. Luke’s CME, the church where her mother ministered. After Simone died on April 21, 2003, she was memorialized at the same sanctuary.

3. SHE WAS BOOK SMART...

Simone, who graduated valedictorian of her high school class, studied at the prestigious Julliard School of Music for a brief period of time before applying to Philadelphia’s Curtis Institute of Music. Unfortunately, Simone was denied admission. For years, she maintained that her race was the reason behind the rejection. But a Curtis faculty member, Vladimir Sokoloff, has gone on record to say that her skin color wasn’t a factor. “It had nothing to do with her…background,” he said in 1992. But Simone ended up getting the last laugh: Two days before her death, the school awarded her an honorary degree.

4. ... WITH DEGREES TO PROVE IT.

Simone—who preferred to be called “doctor Nina Simone”—was also awarded two other honorary degrees, from the University of Massachusetts Amherst and Malcolm X College.

5. HER CAREER WAS ROOTED IN ACTIVISM.

At the age of 12, Simone refused to play at a church revival because her parents had to sit at the back of the hall. From then on, Simone used her art to take a stand. Many of her songs in the '60s, including “Mississippi Goddamn,” “Why (The King of Love Is Dead),” and “Young, Gifted and Black,” addressed the rampant racial injustices of that era.

Unfortunately, her activism wasn't always welcome. Her popularity diminished; venues didn’t invite her to perform, and radio stations didn’t play her songs. But she pressed on—even after the Civil Rights Movement. In 1997, Simone told Interview Magazine that she addressed her songs to the third world. In her own words: “I’m a real rebel with a cause.”

6. ONE OF HER MOST FAMOUS SONGS WAS BANNED.

Mississippi Goddam,” her 1964 anthem, only took her 20 minutes to an hour to write, according to legend—but it made an impact that still stands the test of time. When she wrote it, Simone had been fed up with the country’s racial unrest. Medger Evers, a Mississippi-born civil rights activist, was assassinated in his home state in 1963. That same year, the Ku Klux Klan bombed a Birmingham Baptist church and as a result, four young black girls were killed. Simone took to her notebook and piano to express her sentiments.

“Alabama's gotten me so upset/Tennessee made me lose my rest/And everybody knows about Mississippi Goddam,” she sang.

Some say that the song was banned in Southern radio stations because “goddam” was in the title. But others argue that the subject matter is what caused the stations to return the records cracked in half.

7. SHE NEVER HAD A NUMBER ONE HIT.

Nina Simone released over 40 albums during her decades-spanning career including studio albums, live versions, and compilations, and scored 15 Grammy nominations. But her highest-charting (and her first) hit, “I Loves You, Porgy,” peaked at #2 on the U.S. R&B charts in 1959. Still, her music would go on to influence legendary singers like Roberta Flack and Aretha Franklin.

8. SHE USED HER STYLE TO MAKE A STATEMENT.

Head wraps, bold jewelry, and floor-skimming sheaths were all part of Simone’s stylish rotation. In 1967, she wore the same black crochet fishnet jumpsuit with flesh-colored lining for the entire year. Not only did it give off the illusion of her being naked, but “I wanted people to remember me looking a certain way,” she said. “It made it easier for me.”

9. SHE HAD MANY HOMES.

New York City, Liberia, Barbados, England, Belgium, France, Switzerland, and the Netherlands were all places that Simone called home. She died at her home in Southern France, and her ashes were scattered in several African countries.

10. SHE HAD A FAMOUS INNER CIRCLE.

During the late '60s, Simone and her second husband Andrew Stroud lived next to Malcolm X and his family in Mount Vernon, New York. He wasn't her only famous pal. Simone was very close with playwright Lorraine Hansberry. After Hansberry’s death, Simone penned “To Be Young, Gifted and Black” in her honor, a tribute to Hansberry's play of the same title. Simone even struck up a brief friendship with David Bowie in the mid-1970s, who called her every night for a month to offer his advice and support.

11. YOU CAN STILL VISIT SIMONE IN HER HOMETOWN.

In 2010, an 8-foot sculpture of Eunice Waymon was erected in her hometown of Tryon, North Carolina. Her likeness stands tall in Nina Simone Plaza, where she’s seated and playing an eternal song on a keyboard that floats in midair. Her daughter, Lisa Simone Kelly, gave sculptor Zenos Frudakis some of Simone’s ashes to weld into the sculpture’s bronze heart. "It's not something very often done, but I thought it was part of the idea of bringing her home," Frudakis said.

12. YOU'VE PROBABLY HEARD HER MUSIC IN RECENT HITS.

Rihanna sang a few verses of Simone’s “Do What You Gotta Do” on Kanye West’s The Life of Pablo. He’s clearly a superfan: “Blood on the Leaves” and his duet with Jay Z, “New Day,” feature Simone samples as well, along with Lil’ Wayne’s “Dontgetit,” Common’s “Misunderstood” and a host of other tracks.

13. HER MUSIC IS STILL BEING PERFORMED.

Nina Revisited… A Tribute to Nina Simone was released along with the Netflix documentary in 2015. On the album, Lauryn Hill, Jazmine Sullivan, Usher, Alice Smith, and more paid tribute to the legend by performing covers of 16 of her most famous tracks.

Watch the First-Ever Footage of a Baby Dumbo Octopus

Dumbo octopuses are named for the elephant-ear-like fins they use to navigate the deep sea, but until recently, when and how they developed those floppy appendages were a mystery. Now, for the first time, researchers have caught a newborn Dumbo octopus on tape. As reported in the journal Current Biology, they discovered that the creatures are equipped with the fins from the moment they hatch.

Study co-author Tim Shank, a researcher at the Woods Hole Oceanographic Institution in Massachusetts, spotted the octopus in 2005. During a research expedition in the North Atlantic, one of the remotely operated vehicles he was working with collected several coral branches with something strange attached to them. It looked like a bunch of sandy-colored golf balls at first, but then he realized it was an egg sac.

He and his fellow researchers eventually classified the hatchling that emerged as a member of the genus Grimpoteuthis. In other words, it was a Dumbo octopus, though they couldn't determine the exact species. But you wouldn't need a biology degree to spot its resemblance to Disney's famous elephant, as you can see in the video below.

The octopus hatched with a set of functional fins that allowed it to swim around and hunt right away, and an MRI scan revealed fully-developed internal organs and a complex nervous system. As the researchers wrote in their study, Dumbo octopuses enter the world as "competent juveniles" ready to jump straight into adult life.

Grimpoteuthis spends its life in the deep ocean, which makes it difficult to study. Scientists hope the newly-reported findings will make it easier to identify Grimpoteuthis eggs and hatchlings for future research.
