Seahorses have one of the coolest origin stories of all life on Earth
One of the ocean's worst swimmers has managed to adventure across the world.

How did seahorses spread across the globe if they can't swim well?
We all know that seahorses are some of the most unique and fascinating creatures that Mother Nature has to offer.
For one thing, they’re gorgeous. Who has ever looked at a seahorse, with all its vivid colors and delicate, otherworldly shapes and gone, meh? No one, I tell you.
Plus they’re basically the mascot for cool, supportive dads everywhere. Not every creature in the animal kingdom can say that.
Yet, for as much as we know about the seahorse, there are even more thrilling stories swimming around—particularly when it comes to how it got here in the first place.
A video published by PBS Eons explains that today, seahorses are found in all of the world's oceans. And yet, they are pretty terrible swimmers. So how on Earth could they have traveled such far distances to spread across the globe?
As it turns out, the answer is possibly hiding even further below the surface.
Throughout at least the last 55 million years, the ocean floor around southeast Asia has been whirling with tectonic plate activity, with the most important shift happening at the end of the Cenozoic era.
As deep channels between continents became more shallow and surfaces were thrust upward toward the sun, more aquatic plant life was able to grow and expand. Experts think that meadows of seagrass in particular helped ancient seahorses travel away from the waters of the Indonesian region (where they likely originated) and across the world. Yep, just like land horses, seahorses wildly gallop into unknown terrain. Actually, they prefer to simply hold onto traveling seaweed and raft into unknown terrain. Still majestic though.

The surge in seagrass might have even caused seahorses to trade in the long, horizontal shape of most traditional fish for their signature upright posture. As the video explains, the grass beds might have supported their ambush hunting technique, allowing them to obtain a longer reach and blend in with the grass blades before striking. Ambush hunting seems OK for a seahorse, but kind of terrifying if you think of land horses doing the same thing. Thank goodness the latter are herbivores.

There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.

Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
