Ultimately, the size of a squid or octopus depends on its species, diet, and environment. However, the body shape of squids and octopuses is an important factor in determining their size and hunting strategies.

Fins

This difference in fin structure has a significant impact on the size and mobility of squids and octopuses.

Speed and agility: Squids' fins allow them to swim quickly and maneuver easily in the water. This gives them an advantage over octopuses, which are slower and less agile swimmers.
Size: Squids can grow to be much larger than octopuses, in part because their fins allow them to support their weight and move efficiently through the water.
Habitat: Squids are found in all oceans, while octopuses are more commonly found in warmer waters. This is likely due to the fact that squids' fins allow them to tolerate colder temperatures.

Overall, the presence of fins on squids gives them several advantages over octopuses, including increased speed, agility, size, and habitat range. These advantages make squids better suited for life in the open ocean, while octopuses are better suited for life in shallower waters and near the sea floor.

Arms

The difference in the number of arms between octopuses and squids is a key factor in determining which one is bigger. Squids have ten arms, while octopuses have eight arms. This difference in arm count gives squids an advantage in terms of size and strength.

Squids use their ten arms to capture prey, swim, and defend themselves. The two longer arms, called tentacles, are used to capture prey. The eight shorter arms are used for swimming and crawling. Squids can use their arms to grab onto objects and pull themselves along, which gives them an advantage over octopuses in terms of mobility.

Octopuses, on the other hand, have eight arms that they use for crawling, swimming, and capturing prey. Octopuses are also able to use their arms to change color and texture, which helps them to camouflage themselves from predators and prey.

Overall, the difference in the number of arms between squids and octopuses is a key factor in determining which one is bigger. Squids have ten arms, while octopuses have eight arms. This difference in arm count gives squids an advantage in terms of size and strength.

Diet

The difference in diet between squids and octopuses is a key factor in determining which one is bigger. Squids typically eat smaller prey than octopuses, which allows them to grow to be larger.

Squids are predators that typically eat fish, shrimp, and other small marine animals. They use their long, slender bodies and fins to swim quickly and capture prey. Octopuses, on the other hand, are predators that typically eat crabs, lobsters, and other larger marine animals. They use their shorter, rounder bodies and eight arms to crawl and squeeze into tight spaces to capture prey.

The difference in diet between squids and octopuses is due to their different body shapes and hunting strategies.
