Pygmy killer whales (Feresa attenuata) are a very poorly known species (Donahue & Perryman, 2009; McSweeney et al., 2009), and single sightings or strandings still often warrant publication. Castro (2004) reported an encounter with a school of small cetaceans off Ecuador in 2003, identified by the author as pygmy killer whales, and described details on the behavior of the group. Features noted in the field that were used to determine the species included estimates of their small size (1 to 2.5…

Abstract : Pygmy killer whales (Feresa attenuata) are a rare tropical oceanic odontocete that are normally found close to shore only around oceanic islands (Donahue and Perryman 2009, McSweeney et
The first authenticated record of Pygmy Killer Whale (Feresa attenuata Gray 1874) in Mozambique; has it been previously overlooked?
This is the first authenticated record of Pygmy killer whale in Mozambican waters and the first recent record on the eastern coast of southern Africa since 1970, emphasising the lack of knowledge of offshore marine biodiversity in Moz Mozambique.
Insights into the diet of a poorly known species: pygmy killer whale Feresa attenuata from Cape Verde, West Africa
The stomach contents of two F. attenuata recently stranded in Cape Verde, West Africa, were examined and a variety of fish hard parts and otoliths were recovered, in addition to the upper beak from an unidentified cephalopod and the remains of some marine arthropods.

How to tell them apart? Discriminating tropical blackfish species using fin and body measurements from photographs taken at sea

Pygmy Killer Whale: Feresa attenuata
Site fidelity and association patterns of a rare species: Pygmy killer whales (Feresa attenuata) in the main Hawaiian Islands
Assessment of pygmy killer whales off the island of Hawai’i indicates a small population of island-associated individuals that may be at risk from anthropogenic impacts and association analyses indicate stable long-term associations in mixed-sex groups.
Encounter with a School of Pygmy Killer Whales ( Feresa attenuata ) in Ecuador, Southeast Tropical Pacific
