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.
Each sea star had hundreds of tiny feet on the bottom of each ray. These are tube feet, or podia. These tiny feet can be filled with sea water. The vascular system of the sea star is also filled with sea water.By moving water from the vascular system into the tiny feet, the sea star can make a foot move by expanding it.This is how sea stars move around. Muscles within the feet are used to retract them. Each ray of a sea star has a light sensitive organ called an eyespot.ea Stars Sea stars (group name Stelleroidea) are sometimes called starfish, though they are not real fish (they lack both vertebrae and fins). There are two sub-types of sea stars: 1  Asteroideas are the true sea stars and sun stars. 2  Ophiuroideas are brittle stars and basket stars.
