For example, given their limited tendency for dispersal, Hawaiian monk seal pups can be safely translocated to areas that increase their chance of survival. This chapter reviews over four decades of research dedicated to Hawaiian monk seals, with particular attention to the ethological insigh

The Origin of Phocid Seals and Evolution of Key Behavioral Character Traitsear, suction, and filter-feeding. Phocids were ancestrally shallow water divers with increased diving capabilities evolving among some large-bodied taxa. In terms of mating systems, ice breeding appears to have independently evolved in both clades. Although faunal dynamics are inadequately studied t

Phocid Sensory Systems and Cognition hearing, touch and hydrodynamic perception, chemoreception, and other senses operate effectively under the conflicting demands of marine and terrestrial living and consider how information from individual single sensory systems is integrated to form a multimodal representation of the environment.

Physiological Capacity and Constraint Impact Behavioral Phenotype in Phocid Sealsial behavior. Studies on metabolic and behavioral endocrinology suggest important activational roles for organizing behavior but are relatively unstudied in most species. For these reasons, phocids are an important taxon for comparative studies that examine the evolution of behavior and the role tha

Habitat Utilization and Behavior of Phocid Seals in Relation to Oceanography(biologging) to study movements and the environments utilized. We review the relationships between phocid seal habitat utilization and behavior and the biophysical oceanographic characteristics that directly or indirectly influence the distribution of seals and their prey. The physical properties of

The Harbor Seal: The Most Ubiquitous Phocid in the Northern Hemisphere they eventually become adept predators of fishes and cephalopods in many types of coastal environments. Foraging trips might be a day’s swim from the haulout site or may be two to three weeks duration. Due to their coastal distribution, harbor seals are more susceptible to anthropogenic impacts, su
