It feeds on small prey that it captures using rhythmic movements of its large oral hood. Occasionally it can also be observed floating in the water column or swimming using rhythmic lateral flexions of its entire body. Previous studies have demonstrated that it will swim, and crawl, most often at night. In this issue, the paper by James Newcomb, Winsor Watson, and their students, describes how the locomotion of this species is influenced by a circadian clock that might be associated with its eyes.M. leonina has relatively clear skin, so light can easily reach its eyes. The eyes are located on the brain, which is unusual for gastropods. The main picture shows a M. leonina brain that has been removed and pinned out in a dish of saline where it can be kept alive and will continue to express certain behaviors such as swimming. The eyes have black pigment associated with them; the two white spots lateral to the eyes are neurons with a white pigment. All the other round objects are the cell bodies of individual neurons. The clear structures leaving the brain are nerves.M. leonina has been used by a number of scientists to study the neural basis of behavior because, as is evident from the picture of its brain, its neurons are very large, and readily identifiable. The size, color, and consistent location of these neurons, such as the pair of white pigmented cells adjacent to the eyes, make it possible to insert microelectrodes into individual neurons and record their activity, both in intact animals and in isolated brains. Because the eyes are on the brain, these isolated brains, like intact animals, will express swimming activity more in the dark than in the light. In their article, the authors demonstrated that if the eyes of this species are removed, it is still able to synchronize its daily rhythms to the natural light-dark cycle, suggesting that it probably has other, extraocular, photoreceptors. However, without their eyes, individuals do not exhibit circadian rhythms of locomotion in constant darkness, suggesting that these organs may contain an element of the endogenous biological clock.In view of these facts, this nudibranch provides a good model system for investigating the connection between biological clocks and the neural circuitry underlying behaviors that are expressed with a circadian rhythm.Credits: Large image, Winsor Watson III, University of New Hampshire; inset, James N.
