Sandpipers & Plovers

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.

Sandpiper

The Spotted Sandpiper Actitis macularia is the most common member of a large family of long-legged shorebirds.

They are commonly seen teetering about on beaches and salt marshes, although they may also be found in disused parking lots and other places. The breast is spotted only during the breeding season; in winter it is plain white.

Plovers are similar.


Horned Salp

Thalia democratica

Although they may superficially resemble swimming siphonophores, salps are actually free-living tunicates. There are 6 genera of salps and all are transparent.

Tunicates are much more advanced in the evolutionary scheme of things than jellyfishes, having, for example, a circulatory system. The larvae actually even have several features in common with vertebrates, including the precursor of a spinal cord, but these are lost in the sac-like adults. Salps do not sting.
