I've been seeing a lot of "well I guess this is the way things are now" "ah another line of evidence that we are a fallen empire", attitude that I am begging people to shake off. There are people working their butts off to make things better. Please don't give up. Join us.

graneledone will scavenge mermaidfalls just as readily as whalefalls. the real interesting question is whether or not there are osedax worms specialized to mermaid corpses, as they are often specific to the animal they scavenge (no this is not real, i’m just riffing on one of eduardo’s works)

A midweek montage from the July 2026 #DeepWonders expedition to Trinidad & Tobago w/ @divaamon.bsky.social. The team located over 25 active cold seeps, discovered 20 suspected new species, and mapped approximately 13% of the country’s marine territory.

🚨Not one, but two Magnapinna squid! 🚨 the #doldrums team observed 2 elusive Magnapinna sp., commonly known as bigfin squid, at approximately 4,300 m (about 2.7 miles). Magnapinna is the deepest-dwelling squid. Sightings of these animals are extremely rare — seeing two in one dive is extra exciting!

Ohhh I love this. Winteria telescopa, a species of barreleye - incredibly cute and simultaneously beautiful animal, paddling about in the mesopelagic without a care. (Also, good evidence for my hot take that it's a shame Macropinna is the poster child of the family 💅)

In my interpretation I pair the octopus with the giant ammonite Parapuzosia, these animals aren't known from the same localities but their time ranges overlap which makes it plausible to me that these guys, or close relatives, could have met.
