Abstract

Dolabrifera dolabrifera is an Opisthobranch (sea slug) known for its cryptic coloration. This coloration is an important defense mechanism, but D. dolabrifera have never been studied to see if they change colors to increase their cryptic nature. After photographing 12 D. dolabrifera on different substrates, the color of the slugs and their substrate were determined. These colors were then depicted as hue values. Each D. dolabrifera was photographed three times, in different tide pools and over time. Every D. dolabrifera was graphed with the hue value found for the slug, substrate and reference for the three photographs taken. After analyzing the graphs, I found a correlation between the slug and substrate hue in eight out of the twelve trials. D. dolabrifera changes its color based on its substrate. Dolabrifera dolabrifera es una Opisthobranch (babosa del mar) conocido por su coloración críptica. Esta coloración es un mecanismo de defensa importante, pero nunca se ha estudiado para ver si los D. dolabrifera cambian de color para aumentar su naturaleza crítptica. Después de fotografiar 12 D. dolabrifera en diferentes charcas de mareas a través del tiempo, se determine el color de las babosas y su sustrato. Estos colores fueron luego representados como valores de tono. Cada D. dolabrifera fue fotografiada tres veces, en diferentes charcos de mareas y con el tiempo. Cada D. dolabrifera fue graficado con el valor de tono encontrado para la babosa, sustrato y referencia para las tres fotografías tomadas. Después de analizar los gráficos, encontré una correlación entre los matizes de la babosa y del sustrato en ocho de los doce ensayos. D. dolabrifera cambia su color en función de su sustrato.
