Like all toothed whales, the pygmy sperm whale hunts prey by echolocation. Sound produced for echolocation by many odontocetes come in the form of high-frequency clicks. [20] The frequencies it uses are mostly ultrasonic, [16] peaking around 125 kHz. [20] The clicks from their echolocation has been recorded to last an average of 600 microseconds.
The pygmy sperm whale has an EQ of 1.78, while the dwarf sperm whale's EQ is 1.63. [8] Kogiidae do possess spermaceti in their head like sperm whales. [13] However, kogiid spermaceti is unique as the whales are able to control its temperature. [14] Kogiidae are also homodonts, showing teeth all of the same size and shape. [15]
Nanokogia is an extinct genus of pygmy sperm whale that lived off the coast of ... The absence of functional teeth is also seen in modern pygmy sperm whales and the ...
The dwarf sperm whale has 14 to 24 teeth, rarely 26, in the lower jaw that are sharp, slightly curved backwards, and–like other sperm whales–lack enamel. The teeth rarely exceed 30 mm (1.2 in) in length, smaller than those of the pygmy sperm whale. At most, 6 teeth are in the upper jaws, though in modern sperm whales, upper teeth are defunct.
Sperm whales are massive deep-sea predators with a gray body, pointed teeth and a block-like head. Naturaliste Charters shared a video of the rare encounter on Facebook on March 26. In the video ...
Consequently, its tooth count was lower than those sperm whales, and, aside from the modern dwarf (Kogia sima) and pygmy (K. breviceps) sperm whales, it had the lowest tooth count in the lower jaw of any sperm whale. [1] [8] The most robust teeth in Livyatan were the fourth, fifth and sixth teeth in each side of the jaw. The well-preserved ...
Engraved on the tooth is a picture of the ship Francis, which artist Fred Myrick served on during the early 1800s. Now, sperm whales are protected under the Marine Mammal Protection Act. So, in ...
The pygmy right whale shares several characteristics with the right whales, with the exception of having a dorsal fin. Also, pygmy right whales' heads are no more than one quarter the size of their bodies, whereas the right whales' heads are about one-third the size of their bodies. [11] The pygmy right whale is the only extant member of its ...
