Trump's about to make a bunch of whales, turtles, and dolphins go deaf.
The Trump administration is about to take a preliminary step toward oil and natural gas drilling off the Atlantic shore, by approving requests from energy companies to conduct “deafening seismic tests that could harm tens of thousands of dolphins, whales and other marine animals,” reports the Los Angeles Times.

As a result of noisy ship engines and the racket of ocean mining, bottlenose dolphins have slowly reducing the complexity and changing the frequency of their calls. According to new research from the University of Maryland Center for Environmental Science and published in the journal Biology Letters
, "the noise-induced simplification of dolphin whistles may reduce the information content in these acoustic signals and decrease effective communication, parent–offspring proximity or group cohesion." From YaleEnvironment360
“It’s kind of like trying to answer a question in a noisy bar and after repeated attempts to be heard, you just give the shortest answer possible,” Bailey said. “Dolphins simplified their calls to counter the masking effects of vessel noise.”
Dolphins are highly social animals and use their calls to stay together as a group, talk as they feed, and call out their names when they meet new members of their species. Each animal has a distinctive whistle, which typically uses complex sound patterns with variations in pitch and frequency.

Andrew Hill was stand-up paddleboarding off Gracetown, Western Australia when a pod of dolphins interrupted his fun.
“Eight or nine of them decided to catch that wave and surf straight at me, which has happened lots of times in the past to me and generally they just take off to one side left or right,” Hill told PerthNow. “It's good to see dolphins. Surfers like seeing dolphins, but obviously I'd prefer them to stay a little bit further away than they did yesterday.”
I'm sure they'd prefer the same of Mr. Hill.

Using a black plastic comb and a simple wooden toothpick, a girl beckoned some captive dolphins from the other side of their windowed prison.
Her dad, Brad Meszaros, writes:
My daughter tried several different ways to have the Seaworld dolphins come to her. She tried different toys, a cell phone, tapping the glass, and different movements, none of these worked consistently for her. She did some online research and found the comb method and thought she’d give it a try. The next time she went to SeaWorld, she played the comb for the dolphins and they loved it!
Clever, but SeaWorld? Seriously...? Are we still taking our kids there?

Spectrograms of dolphin calls are closer to written English than the signatures I'm able to scrawl on credit card machines in grocery stores. We really should stop messing with these people—who knows what they might be up to?

Team dolphin all the way, you guys.
A woman at SeaWorld Orlando was trying to take a photograph of the marine mammal show with her iPad, when a dolphin popped up out of the water and grabbed it from her.

In 1964, Margaret Howe Lovatt, working with psychedelic dolphin researcher John Lilly, began to live with one of the animals full-time as part of a NASA-funded study about interspecies communication; a new documentary about Lovatt, titled "The Girl Who Talked to Dolphins," airs on BBC4 later this month. Above, a clip of Lovatt talking about how she developed a deep intimate relationship with Peter the dolphin that veered into the sexual. At the time, a sexploitative article in Hustler, the high weirdness of the experiments itself that included giving LSD to dolphins, and myriad other unpleasant issues, brought the project to a very sad end.

Check out Scicurious' report on a recent research paper entitled "Spontaneous Ejaculation in a Wild Indo-Pacific Bottlenose Dolphin (Tursiops aduncus)" — in which we learn that dolphins can masturbate (yes, even without hands), but, frankly, they don't always need to. That's because male dolphins can have what amount to wet dreams ... sudden, unexpected orgasms that happen in their sleep. And, um, there's video. If you're into that kind of thing. Read the rest

Along the Gulf Coast, people are killing (and sometime gruesomely mutilating) dolphins in record numbers. At National Geographic, Rena Silverman goes in-depth on the killings, which investigators now believe are the work of multiple people who are not connected to one another. Xeni wrote about it last year, when that was apparently less clear. Is it less or more disturbing that this isn't likely to be an isolated dolphin serial killer? Read the rest
