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.
Provide a step-by-step description of how a sea star capture and eats its prey. Answer: The sea star uses its tube feet to move towards and then climb onto the prey, usually some sort of non-moving bivalve. The muscular sea star uses its tube feet to suction onto the shells and then pull them apart.The sea star then inserts its sac-like stomach into the mollusk, secreting digestive enzymes that rapidly break down the mollusks soft interior. The food is sucked back into the sea star along with its stomach.nswer: The sea star uses its tube feet to move towards and then climb onto the prey, usually some sort of non-moving bivalve.
