Unlike the mysticete cetaceans, the boto and the tucuxi did not present a pattern of parallel tracheal folds, because these two species are considered shallow-diving animals and thus do not need to adapt to larger volume changes necessary to make deep dives (Reidenberg & Laitman).
The lowest-frequency noises (1 -20 Hz) are typically caused by seismic activity (e.g., earthquakes); low-frequency noises (20-1000 Hz) are generally caused by shipping and mysticete whales; medium-frequency noises (1-100 kHz) are generally associated with sea state (e.g., wave action); and high-frequency noises (> 100 kHz) result from thermal action (Wenz, 1962; Urick, 1975; Ross, 2005; Au and Hastings, 2008; Hildebrand, 2009).

Fossil abyssochrysoids also were associated with Eocene cold seeps, wood-falls, and bones of odontocete whales (Squires, 1995: Kiel and Goedert, 2007), and with Miocene cold seeps and the bones of mysticete whales (Amano and Little, 2005).
The smallest mysticete is the pygmy right whale (Caperea marginata), which measures up to 23 feet.
