A Bayesian method to estimate the depth and the range of phonating sperm whales using a single hydrophone [PDF]

, 2007
Some bioacousticians have used a single hydrophone to calculate the depth/range of phonating diving animals. The standard one-hydrophone localization method uses multipath transmissions (direct path, sea surface, and seafloor reflections) of the animal ...

Maxillary teeth in sperm whales, Physeter macrocephalus (Cetacea: Physeteridae) [PDF]

Journal of Morphological Sciences, 2015
AbstractSperm whales, Physeter macrocephalus Linnaeus, 1758, have 18 to 28 pairs of well developed conical mandibular teeth, but maxillary teeth are vestigial and supposedly rare. The aim of this study is to report a new case of erupted maxillary teeth in P. macrocephalus, the first description for Brazil.
