Observations of Lolliguncula brevis Schooling in Laboratory Settings
Description/Abstract/Artist Statement
Lolliguncula brevis is a species of squid native to shallow waters of the Atlantic Ocean ranging from Delaware to South America. Many species of squid have been observed in the wild forming complex schools and navigating their environments with respect to one another to maximize hunting effectiveness and minimize the risk of predation; however, it is unclear if Lolloguncula brevis demonstrate this behavior. We recorded Lolliguncula brevis specimens within laboratory settings to determine if they school. Specimens were captured off the coast of the eastern shore of Virginia in the fall of 2022. Squid were observed with a high-speed camera daily for thirty days per collection set. Recording durations ranged from 10 to 60 seconds at 100fps. Measurements of mantle length and distance of target squid from nearest neighbor were made in centimeters along with angles of attack of the target squid in degrees. Analysis of recordings were completed through application of appropriate statistics in R programming. Schooling was determined using degrees of variance from angle of attack of target squid as well as distance from nearest neighbor. The resultant data show that in several recordings, Lolliguncula brevis schooled in nonrandom patterns, suggesting Lolliguncula brevis behave in similar fashion to those of other social species of squid. More research on Lolliguncula brevis is necessary to confirm the statistics and rates of schooling, which may give insight into their life cycles and aid in informing conservation efforts directed towards preserving their populations.
