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.
Size relative to a tea cup: Marine scientists have undertaken the difficult task of replacing the beloved starfishâs common name with sea star because, well, the starfish is not a fish. Itâs an echinoderm, closely related to sea urchins and sand dollars. There are some 2,000 species of sea star living in all the worldâs oceans, from tropical habitats to the cold seafloor. The five-arm varieties are the most common, hence their name, but species with 10, 20, and even 40 arms exist.
