Gentle, precise, fast, and simple method to measure the volume and mass of octopuses without the need to take them out of their tank

Presenting Author: Wolfgang Slany

Affiliation:
Graz University of Technology, Austria.

The Slany method 😉 allows routinely measuring the volume and mass of octopuses with high precision without taking them out of their tank. It does not require any special handling or immobilization of octopuses, besides common husbandry practices such as feeding. The method thus is particularly well suited to gently handle animals without harming them physically or emotionally, in fact it is rewa [...]

Mirror experiment of self – recognition and tool – use of Octopus vulgaris

Presenting Author: Wolfgang Slany

Author: Wolfgang Slany

Affiliation:
Graz University of Technology, Austria

Training 1: A transparent bin contains otherwise identical blue and yellow balls. They are linked through a fishing line which is threaded through an eyelet so that the octopus can only take one ball up to the hole. The octopus receives a reward when she first takes the blue ball to the hole. Control 1: Bin’s open side is attached to a large opaque plate. The octopus cannot look around the plate t [...]

Several papers have described mating in different sepiolines. In this paper, three copulatory acts are described in captive Sepiola affinis (two acts) and Sepiola intermedia (one act; first description of mating in this species). No substantial differences were detected between the two species. In all cases, the male grabbed the fema [...]

Tonic pain is an ongoing, negative affective state arising from tissue damage or inflammation. Because pain is aversive and its relief is innately rewarding mammals learn to avoid a context in which pain is experienced and prefer one where pain relief occurs. It is generally accepted that vertebrat [...]
