    Sperm whale (Physeter macrocephalus) clicks have a multi-pulse structure, a result of the reflection of sound energy between air sacs in the spermaceti organ. Although previous research revealed that usual clicks (used for ...

    The social organization of mammal-eating "transient" killer whales (Orcinus orca) was studied off southern Vancouver Island from 1985 through 1996. Strong and long-term associations exist between individual transients, so ...

    To gain insight into the function of sperm whale vocalizations known as codas (short, patterned series of clicks), sperm whales (Physeter macrocephalus) were tracked continuously for periods of days totalling months off ...
  • The diet of Galapagos sperm whales Physeter macrocephalus as indicated by fecal sample analysis 

    Smith, SC, and H. Whitehead. 2000. "The diet of Galapagos sperm whales Physeter macrocephalus as indicated by fecal sample analysis." Marine Mammal Science 16(2): 315-325.
    Fecal samples were collected while following sperm whales (Physeter macrocephalus) off the Galapagos Islands, Ecuador. They contained 133 upper beaks and 164 lower beaks of cephalopods. Analysis of the lower beaks suggests ...
  • Group-specific dialects and geographical variation in coda repertoire in South Pacific sperm whales
