Squid External Anatomy Student Worksheet Answers
Worksheet Answers
1. What is the purpose of the squid’s mantle?
The mantle of a squid is a muscular organ that surrounds the internal organs and is responsible for jet propulsion, allowing the squid to move quickly through the water.
2. What are the functions of the squid’s tentacles and arms?
The tentacles and arms of a squid are used for capturing prey, manipulating objects, and sensing the environment. They are equipped with suckers that help the squid grip onto its prey.

Squids have large, complex eyes that allow them to see in dimly lit waters. Their eyes are similar to those of vertebrates and provide them with excellent vision for hunting and avoiding predators.
4. How does the squid’s siphon function?
The siphon of a squid is used for expelling water from the mantle cavity, which helps the squid move quickly through the water. It also aids in respiration by allowing water to flow over the gills.
5. What is the purpose of the chromatophores on a squid’s skin?
Chromatophores are pigmented cells on a squid’s skin that allow it to change color and blend in with its surroundings. This helps the squid camouflage itself from predators and prey.
