**V. Feedback from the environment: ** 1. What particular sensory structures does the organism have? What advantage exists for that specific structure? Are there similarities to structures found in the other organisms?  The particular sensory structure for the pig is the big squished up nose. The reason that the pig has this feature is because it allows them to sniff food out easily. They also developed this snout for digging. Another feature of the pig is it's hooves. Pigs have two main hooves much like many other animals such as sheep, goats, deer, cattle, and bison. The two main hooves are called cloven hoof. They also have hoofs called dew-claws a little further up the leg. These dew-claws are not usually used for walking, But they may touch the ground when running or jumping.

 They particular sensory structures that the crayfish has are its claws. The reason that the crayfish developed these claws to be able to grip on to the sand, fight off its predators, and also hold on to its prey. Other animals that have the same claw feature as the crayfish are lobsters and crabs. They also have these claws to grip on to the sand, fight off predators, and hold on to its prey.

 The starfish's particular sensory structure that starfish have two stomachs. The reason that the starfish has two stomachs is because one of the stomachs is used as an alternative to their mouth allowing them to catch and eat larger prey.

2. How has evolution been part of their survival?  Evolution has been apart of the pigs survival because they developed their hooves to be able to walk easily on rough terrain. They also developed these hooves to be able to dig. They developed their flat noses to be able smell food out easily.

<span style="background-color: transparent; color: #000000; font-family: serif; font-size: 16px; text-align: start; text-decoration: none; vertical-align: baseline;">Evolution has been apart of the crayfishes survival because they developed their claw to be able to get food and fight off its predators. The crayfish also developed a hard outer shell to be able to protect its self and live in hard under water conditions. Without the hard outer shell the crayfish would not be able to survive.

<span style="background-color: transparent; color: #000000; font-family: serif; font-size: 16px; text-align: start; text-decoration: none; vertical-align: baseline;"> Evolution has been apart of the starfish because it had to develop the two stomachs to be able to use one as a mouth and one as an actual stomach. If the starfish wouldn’t have evolved and developed another stomach then it wouldn’t be able to eat enough if at all and it would not have survived.
