8th Grade Squid Dissection Takes Deep Dive into Cephalopod Anatomy

The 8th graders found themselves taking a deep dive into their oceanography unit with a squid dissection, led by Prep School science teacher Cary Rosillo. While it was not a requirement for any class, this optional dissection was well attended — the classroom was full! “Squid play a vital role in the marine food web. The dissection served as an investigation into an important class of marine life,” Ms. Rosillo explained.

“Squid and cephalopods are meaningful model organisms with numerous adaptations for communication, locomotion and predation. By dissecting the squid, the students could increase their understanding of invertebrate as well as develop their lab skills and dissection techniques,” Ms. Rosillo said. 

While there are no other formal dissections in the Earth Science curriculum — the science class most often taken by first-year Prep School students — this dissection offered an opportunity to introduce students to a new facet of scientific inquiry. During the 9th grade, students will have another opportunity to dissect a specimen, most likely a rat. In the past, students have worked with fetal pigs as a model of a mammal for their human physiology unit. For students who prefer it, virtual dissections are also available as an alternative learning experience.
