OMS Taken Over by DUI

This website has a link checker, and it just informed me that the OMS link was bad. Sure enough, the website is gone. But it looks like DUI has taken over OMS - the full line of OMS stuff is in the 'OMS' section of DUI's site. So it's probably a good thing, especially in this economic environment. DUI will be around for a long time - they make most if not all of the military's drysuits. Now they have a full line of tech gear; as I recall, I was never too impressed with their own BC designs. Just checked on Dive Rite - they're still there.


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.
