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.
And yes, sea stars as a group are called asteroids. If the food is unprotected by a hard outer covering, like say sea cucumbers or dead fish, the sea star simply lays on top of the prey, everts the stomach and digests away.Animals with shells pose a larger problem.he sea star is an unlikely candidate for the Ruthless Predator Awards, yet of the approximately 1600 species found worldwide nearly every one of them is a carnivore.
