Need help with my writing homework on Material in Squid Beak and Abrasion Resistance. Write a 1500 word paper answering; The tentacles are an intricate part of the result of evolution along with its beak. As biological organisms, squids have fully developed organ systems like the reproductive, digestive, nervous, and cardiovascular systems. The major part of this review constitutes the beak of the squid, which has continued to amaze researchers with its hardness. In addition, its attachment to a soft body. Squids have a head that is the base for both the tentacles and the arms. The beak, which is the main subject of this review is located on the mouth. As noted by ****, the beak is horny and sharp. It is said to be made up of cross-linked proteins and chitin. What is its purpose? It has been opined that it is utilized for tearing prey into consumable portions and killing it at the same time. What is unique about the beak is its toughness. Nevertheless, in spite of the beak being hard, it is said to lack any minerals. Such is the robustness of the squid’s beak that it has been found in the stomach of whales intact.

Because of the lack of minerals to harden the beak, the question has always been how the beak is so hard yet in normal biological settings, it is the minerals that result in the hardness of a tissue. However, the feeding of the squid necessitates that the beak is hard and tough to cut and tear flesh. On examination, the beak of a squid has been compared to that of a parrot. It is composed of two parts that are sharp. Surprisingly, it is implanted into the head, which is composed of soft tissue. Normally, it is usually darker than the other body parts. However, the darkness reduces as the beak moves towards the base, which is the soft tissues of the head. Why is beak hard? It has been discovered that the darkness of the squid’s beak results from a direct relationship with the number of proteins forming it.&nbsp.
