Olfaction is a universal modality by which all animals sample chemical stimuli from their environment. In cartilaginous fishes, olfaction is critical for various survival tasks including localizing prey, avoiding predators, and chemosensory communication with conspecifics. Little is known, however, about interspecific variation in olfactory capability in these fishes, or whether the relative importance of olfaction in relation to other sensory systems varies with regard to ecological factors… Expand
Anatomical Specializations for Enhanced Olfactory Sensitivity in Kiwi, Apteryx mantelli
TLDR
The anatomy of the kiwi Olfactory system supports an enhancement for olfactory sensitivities, which is undoubtedly associated with their unique nocturnal niche. Expand
The role of two anatomically separate olfactory bulbs in shark food odor tracking
TLDR
The results show that animals with lateral tract transection showed impaired ability to track a food odor plume while those with medial transections showed no change, and how the brain is processing input from two anatomically distinct olfactory systems is revealed. Expand
Convergence of Olfactory Inputs within the Central Nervous System of a Cartilaginous and a Bony Fish: An Anatomical Indicator of Olfactory Sensitivity
TLDR
The results support the assertion that relative OB volume is a good indicator of the level of olfactory input and thereby a proxy for Olfactory capabilities. Expand
Diversity in olfactory bulb size in birds reflects allometry, ecology, and phylogeny
The relative size of olfactory bulbs (OBs) is correlated with olfactory capabilities across vertebrates and is widely used to assess the relative importance of olfaction to a species’ ecology. InExpand
Quantification of neurons in the olfactory bulb of the catsharks Scyliorhinus canicula (Linnaeus, 1758) and Galeus melastomus (Rafinesque, 1810).
TLDR
The main aim of this work was to apply isotropic fractionator to investigate the olfactory capability of elasmobranch fishes, whose traditional concept of outstanding olfaction has recently been scaled down by anatomical and physiological studies. Expand
Ontogenetic Shifts in the Number of Axons in the Olfactory Tract and Optic Nerve in Two Species of Deep-Sea Grenadier Fish (Gadiformes: Macrouridae: Coryphaenoides)
TLDR
Comparing the olfactory and visual sensory inputs to the brain in Coryphaenoides armatus and C. profundicolus suggests that both species undergo an ontogenetic shift in sensory orientation, with olfaction becoming relatively more important than vision in larger animals. Expand
The Evolving Neural and Genetic Architecture of Vertebrate Olfaction
TLDR
The coevolution of the OR repertoire and the olfactory system reveals general principles of how the brain solves specific sensory problems and how it adapts to new ones. Expand
Comparative Brain Morphology of the Greenland and Pacific Sleeper Sharks and its Functional Implications
TLDR
Brain organization of S. microcephalus and S. pacificus was assessed in the context of up to 117 other cartilaginous fish species, using phylogenetic comparative techniques, and the region of the brain responsible for motor control is small and lacking foliation, a characteristic not yet described for any other large-bodied (>3 m) shark.

Olfaction in the Zebra Finch (Taeniopygia guttata): What Is Known and Further Perspectives
TLDR
The use of olfaction in social communication and in nonsocial contexts; its impact in addition to other senses throughout life; and how olf action is involved in kin recognition, mate choice, and inbreeding avoidance are summarized. Expand
Anatomy of the olfactory bulb in Greenland shark Somniosus microcephalus (Bloch & Schneider, 1801)
TLDR
In Greenland shark, the olfactory epithelium showed frequent mitosis and apoptosis highlighting the importance of this site in cell renewal, and a deeper understanding of the sensory biology of Greenland shark and of elasmobranchs in general is sought. Expand

TLDR
Significant variation has been identified in the spatial and chromatic sampling of the photoreceptors in the eye, the surface area and the number of olfactory lamellae within the nasal cavity, the type and innervation of neuromasts of the lateral line system, the distribution of electroreceptive pores over the head, and the morphology of the inner ear.

Olfactory morphology and physiology of elasmobranchs
TLDR
Results indicate parallels in olfactory physiology between elasmobranchs and teleost fishes, similar to that previously described in teleosts with neutral amino acids eliciting significantly greater responses than others. Expand

TLDR
All the available evidence points to a great acuity of the olfactory sense in many fish species both in the capability and discriminating odorous chemicals. Expand

TLDR
The pattern of bioluminescent flashing has been observed in two Lampanyctus species, which suggest that the distinct flash patterns may permit species recognition among species that otherwise have similar photophore arrays and also have overlapping habitats. Expand
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
The somatotopic organization of the olfactory bulb in elasmobranchs
TLDR
Results support that the gross arrangement of the elasmobranch OB is somatotopic, an organization unique among fishes and most other vertebrates, and that Somatotopy could provide a preadaptation which facilitated the evolution of olfactory hemibulbs in these species. Expand
Multisensory Integration in Shark Feeding Behavior
TLDR
Three species from different ecological niches were investigated: benthic, suctionfeeding nurse sharks that hunt nocturnally for fish; ram-biting bonnetheads that scoop crustaceans off the bottom of seagrass beds; and ram-feeding blacktip sharks that rapidly chase down midwater teleost prey. Expand
