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 …

Elasmobranchs are thought to possess an acute sense of smell, but the relationship
between the anatomy of their olfactory organs and their sensory ecology is poorly …

Two related but distinct nasal chemosensory systems, the olfactory and vomeronasal
systems, are present in vertebrates as diverse as garter snakes, laboratory mice, and clawed …

Abstract The Greenland shark (Somniosus microcephalus) is the largest predatory fish in
Arctic waters. Knowledge of the fundamental biology and ecological role of the Greenland …

Studies on the brains of teleost fishes have shown that the relative size of sensory brain
areas reflects sensory specialisations and the relative importance of a given sensory system …

The size (volume or mass) of the olfactory bulbs in relation to the whole brain has been used
as a neuroanatomical proxy for olfactory capability in a range of vertebrates, including …

This study investigated the relationship between olfactory morphology, habitat occupancy,
and lifestyle in 21 elasmobranch species in a phylogenetic context. Four measures of …

One of the features common among olfactory systems for vertebrate and invertebrate
species is the division of the primary processing area into distinct clumps of synaptic …

Sharks are practically legendary for their sensory capabilities, with some of this reputation
deserved and some exaggerated. Accounts of sharks being able to smell or hear a single …

The sea lamprey (Petromyzon marinus) is an ancient jawless fish phyletically removed from
modern (teleost) fishes. It is an excellent organism in the study of olfaction due to its …
