Stygiomedusa gigantea was discovered around Antarctica, and has been spotted about once per year over the past century. It’s one meter in diameter, and its tentacles are up to 10 meters long. It’s apparently sometimes known as the “guardian of the underworld”. Image from a Monterey Bay Aquarium Research Institute ROV.
I wrote two research summaries for the organization Sentience Politics.
The Sentience Politics research agenda (plus supplementary documents for my pieces) is here.
Sentience Politics describes itself: “Sentience Politics is an antispeciesist political think tank. We advocate for a society in which the interests of all sentient beings are considered, regardless of their species membership, and we rigorously analyze the evidence to assess and pursue the most effective ways to help all sentient beings. Among other activities, we organize political initiatives, publish scientific policy papers, and host conferences to bring forward-thinking minds together to address the major sources of suffering in the world.” I think their work is valuable and recommend checking them out.
You may not be aware that I have an about page. If you want to commission me to do some research for you, or have suggestions for future posts, let me know.
If anyone has suggestions for ways to make an online dichotomous key, let me know. (Workflowy has been suggested, but I don’t think it’s flexible enough to make a nice-looking large dichotomous key with a lot of options.)
I’m planning on looking through old posts and updating them factually, or at least adding a disclaimer on top to reflect any information I no longer suspect is accurate.
