Microspectrophotometric evidence for cone monochromacy in sharks
TLDR
It is shown that, while the spectral tuning of the rod and cone pigments of sharks varies between species, each shark has only a single long-wavelength-sensitive cone type, suggesting that sharks may be cone monochromats and, therefore, potentially colour blind. Expand
Colour vision and visual ecology of the blue-spotted maskray, Dasyatis kuhlii Müller & Henle, 1814
TLDR
Measurement of the spectral absorption of the rod and cone visual pigments of the blue-spotted maskray, Dasyatis kuhlii, using microspectrophotometry reveals that wavelengths below 380 nm do not reach the retina, indicating that D. kuhLii is relatively insensitive to ultraviolet radiation. Expand
Vision in elasmobranchs and their relatives: 21st century advances.
This review identifies a number of exciting new developments in the understanding of vision in cartilaginous fishes that have been made since the turn of the century. These include the results ofExpand
Morphological Indicators of Olfactory Capability in Wobbegong Sharks (Orectolobidae, Elasmobranchii)
TLDR
Assessing relative olfactory sensitivity in four species of wobbegong shark could indicate relative differences in prey detection, intraspecific recognition and mate detection, and a phylogenetic comparative analysis between wob begongs and other elasmobranchs is presented. Expand
Morphology and distribution of the ampullary electroreceptors in wobbegong sharks: implications for feeding behaviour
TLDR
The morphology of the ampullary organs was examined in four species of wobbegong shark, and the distribution of electroreceptive pores was mapped in two species. Expand
SEMAT — The Next Generation of Inexpensive Marine Environmental Monitoring and Measurement Systems
TLDR
SEMAT is a “smart” wireless sensor network that uses a commodity-based approach for selecting technologies most appropriate to the scientifically driven marine research and monitoring domain/field that allows for significantly cheaper environmental observation systems that cover a larger geographical area and can therefore collect more representative data.

Cone monochromacy and visual pigment spectral tuning in wobbegong sharks
TLDR
In this study, the visual opsin genes of two wobbegong species were isolated to verify the molecular basis of their monochromacy and provide further evidence to support the concept that sharks possess only a single cone type. Expand
Interspecific Visual Adaptations among Wobbegong Sharks (Orectolobidae)
TLDR
While all 4 wobbegong shark species have visual systems optimised for increased visual sensitivity, O. maculatus and O. parvimaculatus appear to be particularly well suited to activity under low light conditions. Expand
A comparison of the electrosensory morphology of a euryhaline and a marine stingray.
TLDR
The morphology of the electrosensory system in a euryhaline elasmobranch species seems very similar to that of their fully marine counterparts, however, some morphological differences are present between these two sympatric species, which are thought to be linked to their habitat type. Expand
The mechanosensory lateral line system in two species of wobbegong shark (Orectolobidae)
TLDR
The study provides evidence that the MLL system of wobbegong sharks is well adapted for their rather unique feeding mode and benthic lifestyle. Expand
