Sperm whales have also been noted to feed on bioluminescent pyrosomes such as Pyrosoma atlanticum. [167] [168] [169] It is thought that the foraging strategy of sperm whales for bioluminescent squids may also explain the presence of these light-emitting pyrosomes in the diet of the sperm whale.

Size comparison between the sperm whale (blue), the pygmy sperm whale (green), and the dwarf sperm whale (orange) The dwarf sperm whale can range in size from 2 to 2.7 m (6.6 to 8.9 ft) in length and 136 to 272 kg (300 to 600 lb) in weight—less than the 4.25 m (14 ft) and 417 kg (920 lb) pygmy sperm whale.
Kogiidae are deep diving whales, believed to dive up to depths of 500 m. [8] Kogiids feed using a technique known as suction feeding, and their diet primarily consists of squid. [20] [21] Pygmy sperm whales are able to eat larger prey than dwarf sperm whales, although their diet as a whole is relatively similar. [21]

And sperm whales function as a family, "Sperm whales are often spotted in groups (called pods) of some 15 to 20 animals. Pods include females and their young, while males may roam solo or move ...
Pygmy sperm whales and dwarf sperm whales are unique among cetaceans in using a form of "ink" to evade predation in a manner similar to squid. Both species have a sac in the lower portion of their intestinal tracts that contains up to 12 liters of dark reddish-brown fluid, which can be ejected to confuse or discourage potential predators.

Many sperm whales have scars on their backs, believed to be caused by the hooks of colossal squid. Colossal squid are a major prey item for sperm whales in the Antarctic; 14% of the squid beaks found in the stomachs of these sperm whales are those of the colossal squid, which indicates that colossal squid make up 77% of the biomass consumed by ...
