do you guys think it would be weird if I emailed a marimo scientist to ask what their upper survivable heat limit is

[osteichthyasss]

There was a study published in The Bulletin of Japanese Society of Phycology in 1965 (Heat Injury in the Marimo Aegagropila sauteri) that found cell death occurs within 24 hours at 35°C and 6 hours at 40°C.

[ID: A photo of a book page that reads

Some of these sex changers can flip with astonishing frequency. The chalk bass (Serranus tortugarum), a neon-blue Caribbean fish that's about the size of your thumb, has been known to switch sex up to twenty times a day. Chalk bass don't do this in order to play the field; quite the opposite - switching sex is their recipe for relationship success. Chalk bass are known to display unusual levels of sexual fidelity and are considered more or less monogamous. Their sex-change habits are a coordinated response with their long-term partner. Researchers believe that taking turns laying eggs, which are bigger and more energy-consuming to produce than sperm, keeps the reproductive investment fair. Each fish fertilizes as many eggs as it produces. Proving that even with fish you get what you give in a relationship.
