Dwarf Sperm Whale
Dwarf Sperm Whale (Kogia Sima) is part of the Kogiidae family within the Kogia genus. The Kogia genus harbors both the dwarf sperm whale and the Pygmy sperm whale (Kogia Breviceps).

Dietary Content
Most dwarf sperm whales feed in the pelagic zone; however they are considered to feed in much shallower waters compared to their neighbor species the Pygmy sperm whale.

The Gulf of Venezuela stretches approximately 3,000 meters where signs of dwarf sperm whale have been located. Mainly these dwarf sperm whales feed along the frontal areas along the shelf where these areas contain rich biomass of epipelagic zooplantons. Zooplanktons play an important role in the kogiid's diet which it primarily consist of cephalopods.

Behavior
Clicking patterns are the standard form of communication for the dwarf sperm whale. Both species within the Kogia genus primarily use clicking as a method to communicate within the waters.

Unlike the Pygmy sperm whale, the acoustic recordings of the dwarf sperm whale are somewhat unknown. However, there have been recordings from both free-ranging and captive dwarf sperm whales. Narrow-bands and high frequency (NBHF) are audio acoustics that were discovered from the dwarf sperm whale where they shared similarities to the Kogia Breviceps.

Free-ranging dwarf sperm whales produces acoustic clicks that are known as “usual” click with mean peaks and centroid of 127-129 kHz.

Mean range: -3 dB bandwidth of 10 kHz.

Mean range: -10 dB bandwidth of 16-17 kHz.

Mean inter-click interval of 110-164 ms.

Human Interactions
Early human interactions began approximately around the 1990s and to to the earlier 2000s. Between the year 2010 and 2014, along the coast of the U.S Atlantic, sighting of dwarf sperm whales and human interaction were recorded. In Florida, a stranded whale was found with its fluke cut offwhile in New Jersey plastic were found located in the stomach pouch of the whale.
