TOLWEB is no longer; in the medium to long term it is being replaced by CephRef: cephref.org

however, until cephref is fully populated, you can view the archived version of the TOLWEB page here:

slide from a presentation on the SERPENT project, which contains a framegrab showing the side view of a peculiar, dull pink squid. the squid is bent in a shallow 'V' shape, with the tip of the V being where the head of the squid meets the mantle. the squid has its arms outstretched with the tips very loosely curled backward toward its body. the long secondary fin is very narrow from this perspective, and appears to be broken or bent just past the halfway point of its total length.

an ROV affiliated with the SERPENT project observed one at an unknown location and date prior to 2009:

framegrab from an ROV dive showing an odd squid. the squid is very narrow and its arms are arranged in a series of odd curls, with two short tentacles hanging downward. instead of a typical mantle fin, the squid has one very small circular fin with ruffled edges and a narrower, feather-like secondary fin extending nearly the length of the mantle again from the end point of the first fin.

an ROV pilot with the energy industry observed one at the Thunder Horse platform in 2017:

People keep telling me they're "not good enough to submit" - I say, we don't gatekeep skill levels.

Sure, I use the books to scout for artists to hire/forward projects to, but our goal is to *encourage people to celebrate nature*.

This is why I insist on having kid & amateur artists each season.

White House to pause $259M in Minnesota Medicaid dollars in fraud crackdown It’s the latest in a growing list of fraud-focused threats and probes from the Trump administration.

This is about political retribution.

Trump is weaponizing the federal government to punish states like Minnesota that didn’t vote for him — ripping away funds from pregnant women, seniors, and people with disabilities.

You don’t fight “fraud” by hurting the most vulnerable.

Former Microsoft executive’s relationship with Jeffrey Epstein comes under scrutiny Seattle Times business reporter Alex Halverson has written about connections between Epstein and former Microsoft executive Nathan Myhrvold.

If the paleo community is going to be serious about Horner’s connection to Epstein, we also have to be serious about Myhrvold’s, because guess who contributed photos of animals mating to Epstein’s birthday book and has been appearing in new paleo papers this year - including the new Spinosaurus.

if you’re used to seeing physonect siphonophores, this will confuse the hell out of you. chuniphyes is still a siphonophore, but a different suborder - calycophoran siphonophores

i was an unradicalized college student at the time and even THEN i remember thinking the department name had really unpleasant authoritarian undertones. the creation of DHS and the patriot act really got the ball rolling for the shitshow we’re at today

the bomber sequence was my white whale, i saw it randomly on MTV's liquid television without any accompanying information back in the 90's. finally figured it out a couple years back. something about zombies chasing after you in a WWII era bomber flying through space apparently captivated young me.

4 valentines in a grid, a pelican eel with the words "You make my jaw drop", an anglerfish that says "You're my light in the darkness", a grimalditeuthis that says "I find you a LURE ing" and two octopuses and a snailfish on the skeleton of a whale that says "I've Whale Fallen for you" lmao. The octopuses are making a heart with their arms together.

Everything is really scary and horrible, and on the utter flipside, we made these really adorable valentines.

The dissonance of seeing horror, then posting "hey buy some cute valentines" is making me feel loopy.

But also nice things persist despite terror? Ugh idk.
