Starfish

Starfish move using a water vascular system. Water comes into the system via the madreporite. It is then circulated from the stone canal to the ring canal and into the radial canals. The madreporite is a rounded plate on the aboral surface of the central disc in inter-radial position. Its surface bears a number of narrow, straight or wavy grooves or furrows. Each furrow contains many minute pores at its bottom. Each pore leads into a very short, fine, tubular pore-canal. The pore-canals unite to form the collecting canals. Which open into an ampulla beneath the madreporite. The ampulla opens into a "S" shaped stone canal. The stone canal extends downwards (orally) and opens into a ring canal, around the mouth. The radial canals carry water to the reservoir (ampulla) portion of tube feet. Each tube foot consists of an internal ampulla and an external podium, or foot. When the ampulla is squeezed, it forces water into the podium, which expands to contact the substrate, a layer that underlies the sea star ex: rocks. In some circumstances the tube feet…

In Sea Stars by Barbara Hurd, she learns about starfish and is then eager to experience them first hand. Hurd begins by taking starfish from and intellectual point of view and in her essay and states, “I know from the charts the moon was full last night, the midnight tide higher than usual. Were the skies clear? Were the stars out? I’d like to have seen these creatures then: stars in the dark overhead and here a spiny constellation draped over the rocks” (CR20). Reading the charts triggers Hurd…

Zootopia, directed by Byron Howard and Rich Moore, is a children’s movie with a much deeper and important message. In the movie, Judy Hopps, a bunny whose whole family works on a carrot farm, becomes Zootopia’s first bunny cop.

Lionfish are venomous Marine fish found in the Pacific and the Indian Ocean. The fish have started invading the Atlantic waters. The Lionfish pose a great danger to the native ecology, and they might destabilize the ecology. They have a large appetite and are well adapted to evade their prey. The lionfish belong to kingdom Animalia and the Phylum Chordata. The fish lives in deep waters in the Coral feeding on the reef fish. The fish develop at a very fast rate such that a fingerling attains…

Middle school is like a big, deep, blue ocean with a clown fish, a sunfish, a box jellyfish, a stone fish, a lionfish, a octopus, a turtle, a seahorse, a squid, a eel, a stingray, a sea cucumber , and a dolphin. The clownfish is Jacob because he is the class clown. The sunfish is Paige because sometimes if someone gets to close to her, she will bit. The box jellyfish is Kaleb because he is such a pain in the butt that he leaves scars wherever he goes. The stonefish is Cameron because he…

Discussion: MY HYPOTHESIS THAT A DECREASE IN STARFISH POPULATION WILL RESULT IN A DRAMATIC INCREASE IN MUSSEL POPULATION was supported by my data. I started with an amount of 60 Starfish in my tidal pool. The results of this scenario was that the average amount of Mussel population was 99 at 60 Starfish. As we went down the line in the number of Starfish present in the start of the experiment the number of Mussel population increased. With the amount of 20 Starfish, the Mussel population…

August 7, 2016 Oce 1001 Mrs. Frey Starfish Star Fish are beautiful creature. They are found mostly in our North-East Atlantic.

Gabe laughed at his haphazardness. Neil went back under water with a splash; not because he wanted to, but he didn’t want them to guess he had been afraid. After a series of dives into the surf, he sat down at the water's edge, clutched his knees with his arms and let the waves slap him in the face. Gabe headed out of the water on to the beach, flagging Neal to join him. He’d found a starfish on the bottom, “I have to show you this.” "This brown creature lacks the ability to move quickly, and…

The Starfish and the Spider – Book Report Stephen J. Reen Indiana University – Purdue University Columbus The Starfish and the Spider – Book Report In 2006, Brafman and Beckstrom set out to answer a question: “What do an encyclopedia, a piece of software, a phone company, classified ads, and naked people in the Nevada desert have in common?” (p. 59). Their resulting book, “The Starfish and the Spider”, describes how Wikipedia, Napster, Skype, Craigslist.com and the annual Nevada party/utopia…

The Starfish nuclear test was the largest of the five tests the United States have detonated in outer space. The fireball can be seen 898 miles away on Oahu and almost immediately, the power grid was wiped out. “Streetlights blew out, circuit breakers tripped, telephone service crashed, aircraft radios malfunctioned, burglar alarms sounded, and garage door openers mysteriously activated (Huard). The aurora borealis was also visible for thousands of miles 7 minutes after the explosion. For years…
