This course is part of a partnership with the Semester in Biological Discovery (SBD) Program of Marine Biological Laboratories (MBL). The SBD program is designed for students interested in biology or biology-adjacent fields and have completed introductory level courses in biology and chemistry. Students accepted to this program will spend the spring semester at the Marine Biological Laboratory (MBL) in Woods Hole, MA. Please see this link for more information on the SBD program: https://www.mbl.edu/education/undergraduate-programs/semester-biological-discovery. Prior to submitting your application to MBL’s Semester in Biological Discovery program, you must meet with the Chair of the Natural Sciences and Mathematics department to discuss your interest and get permission to apply to this program. Since applications to the MBL SBD program are due in the fall semester, you must meet with the Chair in the preceding spring semester or by the first week in the fall semester. Once you have received approval from the Chair you must submit an application to MBL’s Semester in Biological Discovery program. This course takes an integrative approach to understanding a neurally controlled system of dynamic defense against visual predators. Camouflage is a widespread form of defense throughout the animal kingdom in every known habitat - land or sea. In the oceans, cephalopods (cuttlefish, octopus, squid) have evolved a sophisticated sensorimotor system called Rapid Adaptive Coloration, which can instantaneously change their total body appearance within a fraction of a second to range from highly camouflaged to startlingly conspicuous for a wide range of behaviors. The forms and functions of this dynamic system will be teased apart in integrative fashion in a top-down approach from ecology to organismal biology to organs, tissues and cells. The course touches on neural anatomy, sensation, visual perception (including psychophysics) and animal behavior. There are applied biology aspects of this system that will be presented as well, and all of these features align well with the stated goals of the NSCI curriculum. This course is one of two electives – students can select between Dynamic Camouflage: Behavior, Visual Perception and Neural Skin Patterning in Cephalopods or Biological Oceanography. This course satisfies the Intermediate Level Course requirements for the Interdisciplinary Science Major. Permission required to register for this course.
