Sea Butterflies

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.

Naked Sea Butterfly

Naked Sea Butterflies Clione limacina resemble angels. They have a spindle-shaped body up to 1 inch long that is bluish and transparent, with pink to red-yellow areas. The shell is absent. The head is well developed and clearly evident because of an indentation on the upper part of the body. The body has robust flaps ( mantle lobes ) that are used for propulsion. Although it looks like a jellyfish, the Naked Sea Butterfly is a gastropod mollusk, related to snails and sea slugs, and does not sting.

Atlantic Corolla - Carolla calceola

The Atlantic Corolla is a swimming snail with a soft, transparent gelatinous body. It looks like a jellyfish but it is not. A truly planktonic opisthobranch that, being negatively buoyant, must swim with its large wing-like foot.

Schooner Barge

The schooner barge was the final development of the working sailing ship. The design originally evolved in the 1870s on the Great Lakes, where it was found that sailing ships could be more profitably towed from place to place than sailed. No longer subject to the vagaries of the wind, such trips could be made on a scheduled basis, and with reduced labor costs. The idea spread into general use, resulting in the conversion of many sailing ships into barges. Ironically, most of the vessels that were converted to schooner barges were not actually schooners, but square-rigged ships. Square-riggers, with their large and expensive crews of skilled sailors, became uneconomical to operate in the face of ever-improving steam power, while more efficient schooners managed to compete for a few years longer.
