The trachea of the boto and tucuxi is conical and wide, similar to those found in other odontocetes
, as Platanista gangetica and Pontoporia blainvillei (Kida) and Lagenorhynchus acutus (Moore et al.
The general prey consumption process is similar among odontocetes
with the exception of some killer whales (Orcinus orca) that often tear their large prey apart," the report read.
Results of passive acoustic surveys for odontocetes
in the Southern Ocean.
This chapter also details the development of baleen for feeding in mysticetes, the evolution of echolocation in odontocetes
, and the radiations of freshwater cetaceans.
During the survey, 23 cetacean species (17 odontocetes
and 6 mysticetes) were seen, and abundance was estimated for 19 of them (15 odontocetes
and 4 mysticetes).
Neglect of bandwidth of odontocetes
echo location clicks biases propagation loss and single hydrophone population estimates.
Time intervals between clicks in echolocation click trains, termed inter-click intervals (ICI), have been used as a behavioral indicator in several odontocetes
, including harbor porpoise (DeRuiter et al.
Inter-specific behavioral interactions between large whales and small odontocetes
are rarely described and little understood.
Records of odontocetes
in the northern Indian Ocean (1981-1982) and off the coast of Sri Lanka (1982-1984).
First list of odontocetes
from the Canary island, 1980-1987.
2007: Tortonian pontoporiid odontocetes
from the Eastern North Sea.
Generally, mysticetes like blue whales vocalise using lower frequencies creating sounds which can travel over large distances and odontocetes
vocalise using higher frequencies, such as clicking sounds produced by dolphins and sperm whales to echolocate (using sound to Eoe1/4Y[pounds sterling]seeEoe1/4ao .
