Possible monocular range-finding mechanisms in stomatopods from different environmental light conditions

Structure and Optics of Ommatidia From Eyes of Stomatopod Crustaceans From Different Luminous Habitats

“…Stomatopods, predatory Crustacea who catch their prey with a violent strike (Caldwell and Dingle, 1976), have eyes designed presumably for monocular and binocular range-fin^ ng (Schiff^ al, 1985). The eyes are divided into two halves by a middle band (D , 1909;Schiff, 1963Schiff, , 1976Horridge, 1978) of either two or six rows of ommatidia i the species described here.…”

“…That result can now be interpreted in light of our present knowledge. The experiment suggests that not only vibrational simuli are essential for prey catching, but also that optical information is stored or memorized and is retrieved by adding mechanoreceptor inputs (see also Schiff, Abbott, and Manning, 1985). Memory of visual inputs in single fibers has been studied in other crustaceans by Wiersma, Hou, and Martini (1974).…”

The independence of eye movements in a stomatopod crustacean is task dependent

“…When assessing a possible food source, or a potential threat from a conspecific rival, it is crucial for the stomatopod to be able to quickly and accurately determine a salient object's distance from itself in order to maximize the impact of its strike. There is some evidence that stomatopods are able to judge distances with a single eye ( Schiff et al, 1985 , 1986 ; Schiff, 1996 ) but there is limited information about how this is achieved and, to date, neither binocular nor monocular stereopsis has been conclusively shown in stomatopods. Nevertheless, as there is extensive overlap in the fields of view between the left and right eyes and the hemispheres within an eye, stereopsis remains a possibility.…”
