Squid Vs Seaworm Research Paper

If you had to take a bet on which animal would survive the longest, which organism would you bet on? The squid has very good attacking and escaping methods, along with reproducing. The worm has adapted well because of its digestive and reproductive abilities. Squids have also lived longer than segmented worms by millions of years. They have found ways to adapt to their specific environment such as underground and deep in the ocean. The squid is the most successful organism against the worm because of its movement and attacking methods. The worm is quite a successful creature with its adaptations. Worms use setae, or bristle-like structures, to move by having them on each segment of their body. The setae in the back push into the soil around them, then they move front of the body forward and send the front setae out and pull the back part of the body forward in a repeating cycle of movement. Most of the worm’s body is used for eating. Their digestive track …show more content…
The squid moves using jet propulsion and its fins. Jet propulsion is where water is pulled into the squid's body using one way valves, then pushes it forcefully back out to move backwards. The fins in the top of the body are used to move forward during an attack. Speaking of attacks, they have 8 tentacles and 2 arms, both with suction cups on them. During the attack, the squid forms a cone shape while creeping up to their prey, then it opens the 8 tentacles with the 2 arms quickly coming out and grabbing the prey, with the suction cups for holding and gripping. These squids live in deep ocean waters, down to 3,000 feet below the surface, with low oxygen. Since they live very deep waters, the squid have very few predators and if one comes in contact with a predator, it uses its ink sac to expel ink for escaping. The squid is a well survived organism using these adaptations along with reproduction and eating
