Editing Pygmy right whale (section)

== Behavior and ecology ==

Analysis of the stomach contents of dead pygmy right whales indicates that it feeds on [[copepod]]s and [[euphausiid]]s (krill). The social and mating structures are unknown. The whale is typically seen alone or in pairs, sometimes associated with other cetaceans (including dolphins, [[Long-finned pilot whale|pilot whale]]s, [[minke whale]]s, and once a [[sei whale]] cow and calf).<ref name=Kemper/><ref name=Klinowska/><ref name=Shirihai>{{cite book|title=Whales, Dolphins and Other Marine Mammals of the World|author1=Shirihai, H.  |author2=Jarrett, B. |name-list-style=amp |publisher=Princeton Field Guides|year=2006|pages=43–45|isbn=978-0-69112757-6}}</ref> Occasionally larger groups are seen — in 2001 a group of 14 were seen at [[46th parallel south|46°S]] in the South Pacific about 450&nbsp;km southeast of New Zealand, while in 1992 a group of about 80 individuals were seen {{convert|320|nmi|km}} southwest of [[Cape Leeuwin]]<ref name="iucn status 19 November 2021" /> and another group of over 100 individuals were sighted in June 2007 about {{convert|40|km|mi}} southwest of [[Portland, Victoria]].<ref>{{Cite journal |title=Caperea Alive! |journal=Mammal Review |volume=38 |pages=50–86 |year=2010 |url=http://scienceblogs.com/tetrapodzoology/2010/11/08/caperea-alive/ |access-date=30 September 2013|doi=10.1111/j.1365-2907.2008.00118.x |last1=Ford |first1=John K.

The flukes, [[blubber]], and baleen plates of a pygmy right whale calf were found in a 7.47 m (24.5 ft) [[killer whale]] caught by whalers off South Africa.<ref>Best, P.B., A. Meyer, and C.
