Are you managed or monitored?
Shiny things collected by an easily distracted marine biologist. Here you may find fish and other marine critters, land and aerial critters, fannish things, especially of a science fishin' -y, Sherlock-y or cartoonish nature, art and fanart by other people (and very rarely by myself), tea oddities, occasionally my offspring, neurodiversity, cats, and other oddments. Enjoy!
The ask is open, and while I may bite, my teeth are pretty dull.
I am a biologist. That means I find creepy crawlies fascinating. There will be occasional spiders, bugs, and other invertebrates. I do try to tag liberally for those who screen - but if there's anything I need to add, just ask.

Saddleback Anemonefish (Amphiprion polymnus) - Dauin, Philippines
the next generation…so many eyeballs!
Freaked me out for a bit - what anemonefish looks like that?! Does it have some disease? Then the second line clicked, and I looked closer. Ah, eggs; about to hatch, maybe?

SO YOU SWALLOW YOUR WHOLE EFFING FRIEND WOW SOME FRIEND YOU ARE!!!11!
I kid - it’s an angel shark - the definition of an ambush predator - swallowing a much smalller swell shark.
(Angel shark at work)
I once cut out drawings of angel sharks, mounted little wings on their fins, added little tinsel halos and a hanging loop and gave them to people for holiday ornaments.
when the moon hits ur eye like a big pizza pie
when u swim in a creek and an eel bites ur cheek
thats a moray
im still laughing @ this
(if an eel bites your cheek in a creek, it’s probably just a regular eel, but I’ll excuse it for the pun)
We’ve tried lots of strategies for getting salmon over dams to their spawning grounds — fish ladders, fish elevators, fish trucks … even fish helicopters. But all of those methods are expensive and none of them are efficient.
Enter the salmon cannon.
(This reminds me of the old joke: What did the fish say when it ran into a wall? “Dam.”
Maybe they’ll have to change the punchline to “Shoot.”)
Really?! Wow. It says they’re not harmed by it, and the system was developed originally for fragile fruit. I dunno, man; apples and pears don’t have spines, and just because something swims away doesn’t mean it’s not injured. I’m sure they must have done mortality studies…
WHAT KIND OF WIZARD FISH IS THIS
DUDE THATS A BABY KAIJU
SCIENCE SIDE OF TUMBLR URGENT
This fish is not actually spitting bioluminescent spit…it’s spitting out its bioluminescent food! Some clever scientist has put some bioluminescent ostracods in a tank with some little fish. When agitated, these ostracods (tiny shirmpthings) secrete chemicals that, when combined, emit light.
You’re seeing why right here. Just before the fish spits it out, those light chemicals are filling up the belly of the fish. Now, it isn’t poisonous or anything…but the fish wants NOTHING TO DO WITH IT because the fish has predators too.
So yeah, if you’re a little fish and suddenly you’re FREAKING GLOWING, your lifespan has just gotten a lot shorter.
As soon as the fish realizes that there’s light emanating from its belly, it pukes out the glowing juices (and the little shrimp). You can actually see the ostracod in this gif swimming away down toward the bottom of the tank happy as a clam…or a shrimp.
Evolution is AWESOME.

Yet another El Niño sign… These guys (I’m including the remoras attached to the big fella) are way north of where they should be. This video was taken at San Clemente Island, off southern CA. Edit: Deep Sea News has a few more details on the encounter…
At least one sportfishing vessel has reporting catching wahoo (a sort of long skinny tuna, also found in warmer waters) 20 miles of Newport Beach.
Too Close for Comfort. A Great Wonderful Summer (GWS) experience
Local white shark encounter - divers working on removing net from a sunken purse seiner are investigated by (very pregnant-looking) female white shark while making a decompression stop while ascending. Not much place to hide if she decided she wasn’t hungry. However, this is not how whites take their prey usually; they generally ambush things at the surface from underneath - this one seemed to be curious.
Still, if that were me, the water would’ve probably gotten a lot warmer very quickly.

Northern snakeheads - Do you think a fish as invasive and ugly as the northern snakehead could be yummy to eat? There’s a grassroots movement to create a market demand to control the spread of this species.
Um, I thought I’d read that’s kind of how they got to the US in the first place. To eat. You’d think it would be a fine way to get rid of them, but once people start liking something, they tend to want to keep it around, and markets want a steady supply.
We have a similar problem with Chinese mitten crabs in the San Francisco Bay/Sacramento Delta area - not only invasive but they damage the flood-control dykes in the Sacramento River Delta by burrowing. They’re also a delicacy in their home range, but I believe they got here through larvae in ship ballast water. I think you’re allowed to take them recreationally (no limit), but not commercially, thus no incentive to create a fishery with a monetary value.

Some of my coworkers in La Jolla could see this from their office yesterday. Pretty amazing!
Loosing it, in fact.
Felt like drawing some tuna!lock, whoever invented this thing, THANK YOU ❤
