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 used to be called starfish, but they're not fish at all.They're echinoderms, members of the same club as sea urchins, sea cucumbers, sea lilies and sand dollars.hen most sea stars reproduce, they release their swimming larvae to the sea. But the blood star (Herica) holds on to her eggs, forming a pouch with her arms to protect her young. She holds them there, hunched over, until they are fully formed and ready to be released.
