I... I... I HAD 100 shares in my company, AUTOMATICALLY. Well, the stock was up at $51.00 a share, like the highest ever, but the stupid brokerage and paperwork took so dang long when I sold it that by the time the sale was finalized, the stock was only worth $43.00 a share!!!!
The grooves contain rows of tiny, flexible appendages called tube feet. Sea stars move by means of the tube feet, which are operated by a hydraulic, or water-vascular, system unique to echinoderms. Seawater, circulated through the radiating canals of this system, enters and extends the tube feet.ea star, also called starfish, echinoderm of the class Asteroidae, common in tide pools. Sea stars vary in size from under 1/2 in. (1.3 cm) to over 3 ft (90 cm) in diameter. They are commonly dull shades of yellow or orange, but there are many brightly colored ones as well.
Sea stars have a tough covering on their upper side, which is made up of plates of calcium carbonate with tiny spines on their surface. A sea star's spines are used for protection from predators, which include birds, fish and sea otters. One very spiny sea star is the crown-of-thorns starfish, which is shown here.
