During the week I am trying to get back into doing a regular facebook post in the morning. Sometimes, it would be so easy to make the posts here a duplicate of the morning’s writings, but that would be lazy.
Sometimes, I would like to make this a follow on, or slightly deeper comment from the morning. Like tonight. I’ve been looking at the lifecycle of the moon jellyfish.
I have to say that Chat GPT has been very useful in breaking down the lifecycle into easy stages, explaining them in simple language.
One aspect I have been exploring is how the population is regenerated after each cycle. There is a stage in the life cycle called the polyp, these are fixed. Whilst they are vulnerable to events like the ponds being emptied there will be places where they would survive, and it wouldn’t take much to see the population rebuilt to what I see in the ponds. Also, polyps can survive for up to an impressive 25 years.
It seems likely, that the repopulation of the jellyfish population in the cockle ponds mostly comes from polyps that have survived the various draining, with some support from the small mobile stage being brought in.
It’s all fascinating stuff, but it was a real delight to see them back in the ponds. I must admit I don’t know if the model yacht club don’t like them, and I’m sorry for that, but it’s nice to see them back.
