Do jellyfish have a capacity to heal from attacks like this? If so, can anyone describe how it might differ from mammals, or a description in the literature somewhere? I found this fascinating.

I was also curious so I looked it up lol... I only read a little bit but this is a short answer from th article "Many marine animals, including some jellyfish, can rapidly regenerate tissues in response to injury, and this trait is important for survival. If a sea turtle takes a bite out of a jellyfish, the injured animal can quickly grow new cells to replace the lost tissue."

In case you want to read the full article, https://www.caltech.edu/about/news/injured-jellyfish-seek-regain-symmetry-47020#:~:text=Many%20marine%20animals%2C%20including%20some,to%20replace%20the%20lost%20tissue.

Okay but how “quickly?”

They talk about it in the article linked in the linked story. But I’m working, not reading it, I swear.

Instead, within the first two days after the injury, the ephyra had reorganized its existing arms to be symmetrical and evenly spaced around the animal's disklike body. This so-called resymmetrization occurred whether the animal had as few as two limbs remaining or as many as seven, and the process was observed in three additional species of jellyfish ephyra.

I want to point out that ephyra are specifically juvenile jellyfish, so they are likely more resilient to attacks and/or have faster rejuvenation than adults.

wanted to know if the moon jellyfish would respond to injuries in the same manner as an injured hydra. The team focused their study on the jellyfish's juvenile, or ephyra, stage, because the ephyra's simple body plan—a disk-shaped body with eight symmetrical arms—would make any tissue regeneration clearly visible.

In the study they were simply testing if the hydra and the young medusa (ephyra) stages could regenerate.

Ooh, thank you! I’ll give it a read with my morning coffee now that my work’s done. I guess I still have some searching to do.

Since jellyfish life-cycles are typically on the time-scale of months (but varies a bit, a few species live for years), my best guestimate would be a time-scale of ~2 weeks.

Thanks so much! I will definitely read that when aim not trying to distract myself from my work.
