Summary1.This study begins to evaluate how octopuses navigate, and whether they can use visual landmarks. Paths ofOctopus vulgaris were observed in the field as they foraged and responded to displacements.Octopus rubescens were trained to orient to a beacon in the laboratory, and response to its displacement was monitored.2.Octopuses foraged using chemotactile exploration but did not retrace their outgoing paths.3.Octopuses learned to orient to a beacon for a food reward, and oriented directly… Expand

Flexible Spatial Orientation and Navigational Strategies in Chambered Nautilus
TLDR
Testing whether Nautilus pompilius could learn to navigate towards a goal location using either visual cues or motor responses indicates that animals relied both on proximate and distant visual cues to orient but did not use egocentric cues, a somewhat surprising finding given that nautilus spends most of its time in near darkness.

Distance estimation method with snapshot landmark images in the robotic homing navigation
  • Seung-Eun Yu, Daeeun Kim
  • Computer Science
  • 2010 IEEE/RSJ International Conference on Intelligent Robots and Systems
  • 2010
TLDR
A new image-based navigation method, called landmark navigation with distance estimation, which computes the distance to each landmark by using only the visual information of an omnidirectional camea and shows better performance in returning home from an arbitrary location than other methods. Expand
Path integration, views, search, and matched filters: the contributions of Rüdiger Wehner to the study of orientation and navigation
TLDR
The scientific legacy of six topics arising from Rüdiger Wehner's work on navigation are reviewed, including the polarisation compass, which has influenced the study of polarisation vision in other systems, and led Wehner to formulate the concept of a matched filter. Expand
Analyzing the effect of landmark vectors in homing navigation
TLDR
The DELV shows robust homing navigation performance with missing or occluded landmarks among landmark vector methods, and a landmark vector algorithm with a visual compass that uses only retinal images without a reference compass is developed. Expand
A Landmark Vector Approach Using Gray-Colored Information
TLDR
This paper encodes landmark vectors using the gray-colored values as the length of vectors, and applies the landmark arrangement method to those landmark vectors, which can estimate the homing direction at a given position. Expand
Memory of visual and topographical features suggests spatial learning in nautilus (Nautilus pompilius L.).
TLDR
In a small open-field maze, nautiluses learned the location of a goal within 3 trials, and memory was stable for at least 2 weeks, the first evidence for spatial memory in 2- and 3-dimensional arenas is reported. Expand
Landmark vectors with quantized distance information for homing navigation
TLDR
A new landmark vector model with quantized distance information is suggested, and this method is highly successful for navigation without using a reference compass and produces a new type of homing navigation with landmark vectors. Expand
Pull or Push? Octopuses Solve a Puzzle Problem
TLDR
It is indicated that octopuses show behavioral flexibility by quickly adapting to a change in a task by reaching criterion in all levels of the task. Expand
Image-based homing navigation with landmark arrangement matching
TLDR
A new landmark-based matching method for robotic homing navigation that first computes the distance to each landmark based on ego-motion and estimates the landmark arrangement in the snapshot image, which has a higher success rate for returning home from an arbitrary position than do the conventional image-matching algorithms.

Movement patterns of giant Pacific octopuses, Enteroctopus dofleini (Wülker, 1910)
TLDR
Although >90% of their time was spent stationary and hiding, Enteroctopus dofleini utilizes information about its environment (contour following), selects habitats (preference for more kelp cover), and occupies large use areas (minimum convex polygons) by making substantial direct movements from previous use areas.

Landmark learning and visuo-spatial memories in gerbils
TLDR
The aim of this study is to understand what a rodent learns about the geometrical relations between a goal and nearby visual landmarks and how it uses this information to reach a goal, and concludes that a gerbil's representation of its environment is complete. Expand
The use of visual landmarks by honeybees: Bees weight landmarks according to their distance from the goal
TLDR
It is shown here that bees pay most attention to those landmarks which are close to the sucrose and which will therefore guide a bee most accurately to its goal, and that, during their search for the goal, they weight nearer landmarks more heavily than distant ones. Expand
Landmark learning in bees
TLDR
These experiments suggest that bees learn no more than the apparent size and bearing of the landmark as seen from the food source, and that to return there they move to a position where their retinal image matches their remembered image of the landmarks. Expand
Some psychophysics of the pigeon's use of landmarks

  • Journal of Comparative Physiology A
  • 2004
TLDR
Three pigeons were trained to find hidden food in a sunken well at a constant place within an experimental box with the animals tested occasionally with the well and food absent, finding that changing the height or width of a nearby landmark had no systematic influence on the position of peak search.

Limitations in the Assessment of Path Dependent Information
When hoarding food in an experimental arena (o = 2.20 m), golden hamsters tend to return along a direct path from the food source at the centre of the arena to their peripherally located nest. UnderExpand
The effect of a single light cue on homing behaviour of the golden hamster
Golden hamsters, Mesocricetus auratus W., tend to return directly from a food source at the centre of an experimental arena to their peripheral nest. The subjects' choice of a particular homingExpand

For navigation, desert ants apply piloting and dead-reckoning strategies based on terrestrial and celestial visual cues, respectively. Visual spatial memories, rather than general concepts derivedExpand
A study of the homing habit of the limpet
Abstract 1. 1. About 400 limpets were observed in June and July 1967 and 1968 at Saye Bay, Alderney, in the Channel Islands, in order to study their homing behaviour. 2. 2. Movements of limpets wereExpand

TLDR
Four individual Octopus dofleini were followed over a fifteen day period in their underwater habitat by sonic tracking, suggesting they were solitary and non‐social. Expand
