Sperm whale sound production

largest, yet most elusive, creatures inhabiting deep ocean waters. Adult sperm whales undertake long, deep dives (Watkins et al., 1993) into the darkness and high pressure of the mesoand bathypelagic depths. They do this to locate and catch approximately 1000 kg (Lockyer, 1981) of medium-sized squid and fish (Clarke et al., 1993) each day. The most prominent feature of the sperm whale physique ...

Sperm Characteristics in Cryopreserved Buffalo Bull Semen and Field Fertility

Semen quality and its relationship to fertility are major concern in animal production. The aim of this study was to assess the relationship between frozen thawed sperm characteristics and fertility following in vivo fertility through Artificial Insemination(AI). Semen samples were collected from four buffalo bulls. Semen volume and sperm concentration appeared to be significantly different (P0...

Electrostatic Interactions in Sperm Whale Myoglobin

The electrostatic free energy contribution to the stability of sperm whale ferrimyoglobin was evaluated according to the static accessibility modified TanfordKirkwood model. The electrostatic free energy contribution of each distinct structural element was divided into one term arising from interactions between it and other elements (interelemental) and another from interactions within the part...

Energy Conversion in Bull Sperm Flagella

With the use of a specially developed incubation chamber the rates of motility, respiration, and fructolysis were measured simultaneously on semen samples. By inhibiting the respiration with antimycin A, and/or the fructolysis with 2-deoxyglucose, the rates of each of the two ATP-producing pathways could be reduced independently. In this way the ratio of the amount of free energy produced by re...

Click production during breathing in a sperm whale (Physeter macrocephalus).

A sperm whale (Physeter macrocephalus) was observed at the surface with above- and underwater video and synchronized underwater sound recordings. During seven instances the whale ventilated its lungs while clicking. From this observation it is inferred that click production is achieved by pressurizing air in the right nasal passage, pneumatically disconnected from the lungs and the left nasal p...
