Adaptation and How it Helps the Organism Survive:

1. Tube Feet

2. Water Vascular System

3. Ability to Regenerate Body Parts

4. Spines

5. Pincers

6. Stomach that Extends Outside the Body

[Noah Abraham]

Adaptation and How it Helps the Organism Survive:

1. Tube Feet- By expanding and retracting the right tube feet in the proper order, the creature can walk. Many echinoderms can also form suckers on the ends of their tube feet. These suckers can be used to capture and hold prey, or to hold onto rocks in a swift current or tide.
2. Water Vascular System- By expanding and contracting chambers within the water vascular system, the echinoderm can force water into certain tube feet to extend them
3. Ability to Regenerate Body Parts-Sea stars are capable of regenerating limbs in the event that one or more is severed or damaged. The wound first closes off, and in time, the new limb will begin to grow. Allows for survival after being damaged.
4. Spines-offers protection from predators
5. Pincers-plucks things off the skin of sea stars that may damage them
6. Stomach that Extends Outside the Body-if attacked by a predator, it can expel some of it's organs to satisfy or scare off the predator

1. Tube Feet -  trait common to all echinoderms. By examining the oral (ventral or underside) side of a sea star, one will be able to see hundreds of tiny feet usually arranged into several rows on each ray (appendage) of the star. These are called tube feet, orpodia, and are filled with sea water in most echinoderms. 

2. Water Vascular System - The water vascular system within the body of the animal is also filled with sea water. By expanding and contracting chambers within the water vascular system, the echinoderm can force water into certain tube feet to extend them.

3. Ability to Regenerate Body Parts - Sea stars are capable of regenerating limbs in the event that one or more is severed or damaged. The wound first closes off, and in time, the new limb will begin to grow

4. Spines - The sea urchins are well known to most people, having a large number of sharp spines pointing out in all directions. These spines offer protection from many would-be predators. The spines are joined to the skeleton of the animal, called the "test," in a form of ball-joint.

5. Pincers - scissor-like or forceps-like structures, that come in variety of sizes. They are designed to protect the creature and can hold prey for up to 48 hours

6. Stomach that Extends Outside the Body - Seizing the moment, the sea star then everts its stomach out through its mouth, and into the mussel (only a 1/100th of an inch opening is required). Once the sea star begins to digest its victim within the victim's own body, the victim dies. The sea star then finishes the meal by consuming the rest of the mussel.

Tube feet - these help the creature stick to flat surface and help them blend into their environment.
Water vascular system- this helps the creature filters the water and also helps them be able to function properly.
Regenerate body parts-
Spines help the creature protect itself and helps the creature keep its body formation.
Pisters- helps the fish focus and concentrate on it's eating and solslising.
Stomach that extends - this helps the creature defend itself as well and helps it blend into the enviornment. Also alouse the creature to eat more food.

1. Tube Feet- used to help the starfish move and catch prey

2. Water Vascular System- controls the tube feet

3. Ability to Regenerate Body Parts- grows new limbs if it looses any, and sometimes create new starfish all together

4. Spines- it keeps it alive

5. Pincers- keeps other organisms from growing on the starfish

6. Stomach that extends outside the body- ability to engulf the prey while prying the shell open.

1) to help it move brilliantly through its environment

2) this helps it move eat and rseperate

3) ability to regenerate body if it where to be damaged

4) to act as a defence against predators

5)They are designed to protect the creature and can hold prey for up to 48 hours.

6)eizing the moment, the sea star then everts its stomach out through its mouth, and into the mussel.. Once the sea star begins to digest its victim within the victim's own body, the victim die... The sea star then finishes the meal by consuming the rest of the mussel..
