Predators make foraging decisions based upon sensory information about resource availability, but little is known about how large, air-breathing predators collect and use such information to maximize energy returns when foraging in the deep sea. Here, we used archival tags to study how echolocating sperm whales (Physeter macrocephalus) use their long-range sensory capabilities to guide foraging in a deep-water habitat consisting of multiple, depth-segregated prey layers. Sperm whales employ a…

Movement and Biosonar Behavior During Prey Encounters Indicate That Male Sperm Whales Switch Foraging Strategy With Depth
TLDR
The diverse prey base indicated by this study support the feeding requirements of large male sperm whales, and that high feeding rates of more densely distributed and perhaps more predictable resources likely maintain preference for the deepest foraging habitats of this generalist predator.
Risso's dolphins plan foraging dives
TLDR
Perceptual, spatial memory and sensorimotor control information are integrated by Risso's dolphins to adaptively plan foraging on prey of varying quality and predictability in multiple depth layers.
Sperm whale predator-prey interactions involve chasing and buzzing, but no acoustic stunning
TLDR
It is shown that in the terminal buzz phase, sperm whales reduce inter-click intervals and estimated source levels by 1–2 orders of magnitude, precluding acoustic stunning to facilitate prey capture and involves high-frequency, low amplitude clicks well suited to provide high-resolution biosonar updates during the last stages of capture.
The long-range echo scene of the sperm whale biosonar
TLDR
It is concluded that the powerful biosonar of sperm whales enables long-range echolocation and selection of prey, but not acoustic debilitation, which is in keeping with the lower manoeuvrability of these large predators.
Social Ecology of Feeding in an Open Ocean
TLDR
This chapter focuses on epipelagic and mesopelagic odontocetes, and is learning more about how deep-diving dolphins and whales forage, and coordination there seems likely as well.
Deep-diving pilot whales make cheap, but powerful, echolocation clicks with 50 µL of air
TLDR
Frugal use of air and periodic recycling of very limited air volumes enable pilot whales, and likely other toothed whales, to echolocate cheaply and almost continuously throughout foraging dives, providing them with a strong sensory advantage in diverse aquatic habitats.
Diverse foraging strategies by a marine top predator : Sperm whales exploit pelagic and demersal habitats in the Kaik ō ura submarine canyon
The submarine canyon off Kaikōura (New Zealand) is an extremely productive deep-sea habitat, and an important foraging ground for male sperm whales (Physeter macrocephalus). We used high-resolution
Diverse foraging strategies by a marine top predator: Sperm whales exploit pelagic and demersal habitats in the Kaikōura submarine canyon
TLDR
Some evidence for circadian patterns in the foraging behaviour of sperm whales is found, which might be related to vertical movements of their prey following the deep scattering layer, and explored the ecological implications of the whales’ foraging preferences on their habitat use.

TLDR
Preliminary results show how this technique can be applied to the study of deep diving whale foraging and habitat selection and how the density of prey decreased with depth and where the size of prey increased with depth.
Acoustic analysis of slow click function and foraging in sperm whales (Physeter macrocephalus) off Kaikoura, New Zealand
TLDR
Acoustic analysis of slow click function and foraging in sperm whales (Physeter macrocephalus) off Kaikoura, New Zealand suggests that slow clicks display a broad but somewhat directionality, which may allow slow clicking whales to target goals by adjusting their body posture.

Following a Foraging Fish-Finder: Diel Habitat Use of Blainville's Beaked Whales Revealed by Echolocation
TLDR
The biosonar system of Blainville's beaked whales is tapped into, using sound and orientation recording tags to uncover prey-finding cues available to echolocating predators in the deep-sea, suggesting that these whales are accessing prey in reliable vertical strata.
Echolocation behaviour adapted to prey in foraging Blainville's beaked whale (Mesoplodon densirostris)
TLDR
It is demonstrated that the clicking rate at the beginning of buzzes is related to the distance between whale and prey, supporting the presumption that whales focus on a specific prey target during the buzz, and indicates that toothed whales in the wild can adjust their echolocation behaviour and movement for capture of different prey on the basis of structural echo information.
Sperm whale behaviour indicates the use of echolocation click buzzes ‘creaks’ in prey capture
TLDR
The hypothesis that creaks are an echolocation signal adapted for foraging, analogous to terminal buzzes in taxonomically diverse echlocating species, strongly support the hypothesis thatcreaks are produced during prey capture.
Male sperm whale (Physeter macrocephalus) acoustics in a high-latitude habitat: implications for echolocation and communication
TLDR
It is concluded that echolocation is an important sensory cue in prey location and sperm whales producing slow clicks may represent an odontocete species that utilizes long-range sound communication.
HOW DO SPERM WHALES CATCH SQUIDS
TLDR
Two complementary hypotheses regarding the detection and capture of prey items are presented, based on a review of mesopelagic ecology, which postulates that sperm whales locate their prey visually or create a zone of stimulated bioluminescence around the mouth, which attracts squids and other visual predators.
Echolocation in Blainville’s beaked whales (Mesoplodon densirostris)
TLDR
Here sound and movement recording tags are used to study how deep-diving Blainville’s beaked whales use echolocation to forage in their natural mesopelagic habitat.
Shallow food for deep divers: Dynamic foraging behavior of male sperm whales in a high latitude habitat
TLDR
The evidence of exploitation of different food layers, including epipelagic prey, is consistent with the hypothesis that male sperm whales may migrate to high latitudes to access a productive, multi-layered foraging habitat.
The function of male sperm whale slow clicks in a high latitude habitat: communication, echolocation, or prey debilitation?
TLDR
Some slow clicks were emitted in seemingly repetitive temporal patterns supporting the hypothesis that the function for slow clicks on the feeding grounds is long range communication between males, possibly relaying information about individual identity or behavioral states.
Cheetahs of the deep sea: deep foraging sprints in short-finned pilot whales off Tenerife (Canary Islands).
TLDR
This energetic foraging tactic focused on a single or few prey items has not been observed previously in deep-diving mammals but resembles the high-risk/high-gain strategy of some terrestrial hunters such as cheetahs.
From spatial orientation to food acquisition in echolocating bats
TLDR
This conceptual framework calls for a new view on field data from bats orienting and foraging in different types of habitats according to the ecological constraints in which foraging bats operate, four distinct functional groups or guilds within each group, signal design and echolocation behavior are rather similar.
