  • Aminoglycoside-induced damage in the statocyst of the longfin inshore squid, Doryteuthis pealeii 

    Scharr, Alexandra L.; Mooney, T. Aran; Schweizer, Felix E.; Ketten, Darlene R. (Marine Biological Laboratory, 2014-08-01)
    Squid are a significant component of the marine biomass and are a long-established model organism in experimental neurophysiology. The squid statocyst senses linear and angular acceleration and is the best candidate for ...
  • The auditory anatomy of the minke whale (Balaenoptera acutorostrata) : a potential fatty sound reception pathway in a baleen whale 

    Yamato, Maya; Ketten, Darlene R.; Arruda, Julie; Cramer, Scott R.; Moore, Kathleen M. T. (John Wiley & Sons, 2012-05-12)
    Cetaceans possess highly derived auditory systems adapted for underwater hearing. Odontoceti (toothed whales) are thought to receive sound through specialized fat bodies that contact the tympanoperiotic complex, the bones ...
  • Auditory temporal resolution and evoked responses to pulsed sounds for the Yangtze finless porpoises (Neophocaena phocaenoides asiaeorientalis) 

    Mooney, T. Aran; Li, Songhai; Ketten, Darlene R.; Wang, Kexiong; Wang, Ding (2011-08-09)
    Temporal cues are important for some forms of auditory processing, such as echolocation. Among odontocetes (toothed whales, dolphins, and porpoises), it has been suggested that porpoises may have temporal processing ...
  • Beaked whale necropsy findings for strandings in the Bahamas, Puerto Rico, and Madeira, 1999-2002 

    Ketten, Darlene R. (Woods Hole Oceanographic Institution, 2005-11)
    Necropsy and histologic findings for examinations performed on beaked whales stranding between October, 1999 and June, 2002 are summarized and the finding interpreted. They are presented in chronological order of exams ...
  • Characterization of lipids in adipose depots associated with minke and fin whale ears : comparison with “acoustic fats” of toothed whales 

    Yamato, Maya; Koopman, Heather N.; Niemeyer, Misty E.; Ketten, Darlene R. (2014-01)
    In an underwater environment where light attenuates much faster than in air, cetaceans have evolved to rely on sound and their sense of hearing for vital functions. Odontocetes (toothed whales) have developed a sophisticated ...
  • Deadly diving? Physiological and behavioural management of decompression stress in diving mammals 

    Hooker, Sascha K.; Fahlman, Andreas; Moore, Michael J.; Aguilar De Soto, Natacha; Bernaldo de Quiros, Yara; Brubakk, A. O.; Costa, Daniel P.; Costidis, Alexander M.; Dennison, Sophie; Falke, K. J.; Fernandez, Antonio; Ferrigno, Massimo; Fitz-Clarke, J. R.; Garner, M. M.; Houser, Dorian S.; Jepson, Paul D.; Ketten, Darlene R.; Kvadsheim, P. H.; Madsen, Peter T.; Pollock, N. W.; Rotstein, David S.; Rowles, Teresa K.; Simmons, S. E.; Van Bonn, W.; Weathersby, P. K.; Weise, M. J.; Williams, T. M.; Tyack, Peter L. (Royal Society, 2011-12-21)
    Decompression sickness (DCS; ‘the bends’) is a disease associated with gas uptake at pressure. The basic pathology and cause are relatively well known to human divers. Breath-hold diving marine mammals were thought to be ...
  • Hearing pathways in the Yangtze finless porpoise, Neophocaena asiaeorientalis asiaeorientalis 

    Mooney, T. Aran; Li, Songhai; Ketten, Darlene R.; Wang, Kexiong; Wang, Ding (Company of Biologists, 2013-10-18)
    How an animal receives sound may influence its use of sound. While ‘jaw hearing’ is well supported for odontocetes, work examining how sound is received across the head has been limited to a few representative species. The ...
  • Imaging procedures for stranded marine mammals 

    Ketten, Darlene R.; Montie, Eric W. (Woods Hole Oceanographic Institution, 2008-01)
    This section provides an introduction to biomedical imaging techniques and guidelines for diagnostic imaging of marine mammals to assist with both live examination and necropsy procedures. The procedures described are ...
  • A manual for the removal, fixation and preservation of cetacean ears 

    Ketten, Darlene R.; Cramer, Scott R.; Arruda, Julie (Woods Hole Oceanographic Institution, 2007-01)
    This chapter is intended as an instructional guide for the removal, fixation and preservation of auditory system tissues of marine mammals. Each section describes procedures for a major ear type for marine mammals. The ...
  • Potential for sound sensitivity in cephalopods 

    Mooney, T. Aran; Hanlon, Roger T.; Madsen, Peter T.; Christensen-Dalsgaard, Jakob; Ketten, Darlene R.; Nachtigall, Paul E. (2010-07)
    Hearing is a primary sense in many marine animals and we now have a reasonable understanding of what stimuli generate clear responses, the frequency range of sensitivity, expected threshold values and mecha-nisms of sound ...
  • Sonar-induced pressure fields in a post-mortem common dolphin 

    Foote, Kenneth G.; Hastings, Mardi C.; Ketten, Darlene R.; Lin, Ying-Tsong; Reidenberg, Joy S.; Rye, Kent (Acoustical Society of America, 2012-02)
    Potential physical effects of sonar transmissions on marine mammals were investigated by measuring pressure fields induced in a 119-kg, 211-cm-long, young adult male common dolphin (Delphinus delphis) cadaver. The specimen ...
  • Three-dimensional geometry of the narwhal (Monodon monoceros) flukes in relation to hydrodynamics 

    Fontanella, Janet E.; Fish, Frank E.; Rybczynski, Natalia; Nweeia, Martin T.; Ketten, Darlene R. (2010-09-03)
    Cetaceans (whales, porpoises, and dolphins) use only their flukes for propulsion. Flukes are distally located extensions of the tail, and from a biomechanical standpoint, function as a pair of wings (Vogel 1994). Flukes ...
  • Unique biochemical and mineral composition of whale ear bones 

    Kim, Sora L.; Thewissen, J. G. M.; Churchill, Morgan M.; Suydam, Robert S.; Ketten, Darlene R.; Clementz, Mark T. (University of Chicago Press, 2014-06-03)
    Cetaceans are obligate aquatic mammals derived from terrestrial artiodactyls. The defining characteristic of cetaceans is a thick and dense lip (pachyosteosclerotic involucrum) of an ear bone (the tympanic). This unique ...
