...Marisa S. McDonald; Jonathan H. Cohen; Megan L. Porter ABSTRACT Larval stomatopods have generally been described as having a typical larval crustacean compound eye, which lacks the visual pigment diversity and morphological specializations of the well-studied stomatopod adult eye. However, recent...

...Marisa S. McDonald; Sitara Palecanda; Jonathan H. Cohen; Megan L. Porter ABSTRACT Stomatopod crustaceans have among the most complex eyes in the animal kingdom, with up to 12 different color detection channels. The capabilities of these unique eyes include photoreception of ultraviolet (UV...

.... Flat targets made of colored, transparent plastic cemented on a solid white background were placed at the end of each choice arm. Four targets were used during the experiment: a red rectangle, a green rectangle, a red triangle and a green triangle ( Fig. 1 A,B). Because stomatopods in previous...

...Tsyr-Huei Chiou; Ching-Wen Wang ABSTRACT Stomatopods, or mantis shrimp, are the only animal group known to possess circular polarization vision along with linear polarization vision. By using the rhabdomere of a distally located photoreceptor as a wave retarder, the eyes of mantis shrimp are able...

...Rachel M. Templin; Martin J. How; Nicholas W. Roberts; Tsyr-Huei Chiou; Justin Marshall ABSTRACT A combination of behavioural and electrophysiological experiments have previously shown that two species of stomatopod, Odontodactylus scyllarus and Gonodactylaceus falcatus , can differentiate between...

.... Several marine species, such as stomatopod crustaceans and cephalopod molluscs, communicate using visual signals that contain polarized information, content that is often part of a more complex multi-dimensional visual signal. In this work, we investigate the evolution of polarized signals in species...

.... Transparent, pelagic animals must therefore deal with the trade-off between the ability to see and the ability of other animals to see them. Stomatopod larvae, like many transparent crustaceans, possess specialized optics in their compound eyes that minimize the volume of the opaque retina. Though the volumes...

... with light such as birefringence, differential reflection or scattering. We describe a novel biological polarizer in a marine crustacean based on linear dichroism of a carotenoid molecule. The red-colored, dichroic ketocarotenoid pigment astaxanthin is deposited in the antennal scale of a stomatopod...

... by waves. We compared signal encounters by odor-plume-tracking stomatopods (mantis shrimp) in wave-affected and unidirectional flow in a flume. Stomatopods are small enough that we can study their natural behavior in a flume. They sample odors by flicking their antennules. A thin sheet of laser light...

...K. S. Mead; M. A. R. Koehl ABSTRACT Many crustaceans detect odors from distant sources using chemosensory sensilla (aesthetascs) on their antennules. The greater the flow of water through arrays of aesthetascs, the faster the access of odorant to receptors inside the aesthetascs. Stomatopods...
