Swatting Bugs

October 18, 2020

Well, it's that time of year again, time to renew the web hosting. And for those of you that don't know, that has become a lot more expensive than it used to be. Fifty dollars a year is now several hundred. Not to mention the price of domain names has gone up ten-fold.

And I just found out that the nice folks at PayPal disabled all my Support buttons, and I never got a notice (although that may be my fault.) In any case, it is all working again now, so if you would like to make a small donation to help defray these costs, it would be greatly appreciated.

I turned on the strictest and most verbose error reporting in both WordPress and PHP, and got a pile of non-critical error messages. It was pretty ugly. So I spent a while and fixed them all; actually, it didn't take that long. I don't like to be sloppy, just because the system can tolerate an error doesn't mean you should leave it.

Stubbed-in all the remaining extra files in Dive Sites and Artificial Reefs, and organized them, with Contents pages listing everything. Then I did the same for the Home section. Now up to 660 (blank) pages. Next - Biology.

True Jellyfishes

Jellyfishes

Jellyfishes are free-swimming relatives of corals, anemones, and hydroids. In fact, in many cases, they are the same species, just in a different stage of life! Not all medusas ( as jellyfishes are called ) have a corresponding polyp stage, and likewise, not all polyps have a corresponding medusa stage, but most alternate generations in each form. Small jellies ( up to 1" across ) are most likely the medusa stage of some hydroid, while large jellies are usually the dominant stage of a species in which the polyp stage is almost absent. Even anemones have a periodic medusa stage, although it is infrequently observed.

Although jellyfish can swim slowly, they are largely at the mercy of the tides and currents, and at times large numbers are concentrated into bays and may be stranded on beaches.
