Oikos, Volume 2026, Issue 7, July 2026.Some prey species have evolved background matching, that is they resemble their surrounding environment in terms of colour and/or brightness. When prey populations inhabit patchy environments, they may even have evolved specialised phenotypes: each phenotype matching a specific subset of patches.

Involvement of chemical perception in control of reproduction in Octopus vulgaris [PDF]
, 2017 Among invertebrates reproductive strategies are much more diversified than vertebrates. Recently we have found in Octopus vulgaris that olfactory sensory neurons (OSNs) express several peptides involved in reproduction and feed intake such as GnRH and ...

Journal of Venomous Animals and Toxins including Tropical Diseases, 2014 Several species of octopus are considered venomous due to toxins present in the glands connected to their “beak”, which may be associated with hunt and kill of prey. Herein, we report an accident involving a common octopus (Octopus vulgaris) that injured

Drivers of change in human–wildlife relationships: Southern Africa as an example
People and Nature, Volume 8, Issue 7, Page 2233-2250, July 2026.Abstract Human–wildlife relationships (HWRs) are changing globally in response to shifts in ecological dynamics and societal values, often resulting in contestation. With an increasing need to enable human–wildlife coexistence, it is essential to better understand the drivers of change in HWRs.

CADMIUM IN OCTOPUS VULGARIS: AN INPUT TO ASSESS HUMAN HEALTH RISK
Italian Journal of Food Safety, 2009 Cadmium concentrations has been evaluated in Octopus vulgaris sampled from two sites of Apulian coast (South Italy) and compared with import cephalopods to estimate if maximum levels of cadmium established for these organisms by the European Commission ...

Marine Mammal Science, Volume 42, Issue 3, July 2026.ABSTRACT The common bottlenose dolphin (Tursiops truncatus) is a resident species along the Portuguese mainland coast, yet knowledge of its stranding patterns and feeding ecology is scarce. This study presents a comprehensive assessment of strandings (n = 264, from 1980 to 2019) and feeding ecology based on stomach content analysis (n = 43 from 1997 to

First description of parasitation by Agregata octopiana in common octopus, Octopus vulgaris, in Canary Islands [PDF]
, 2013 The negative effects that infections with the coccidian parasite Aggregata octopiana has in cephalopods is widely known. However, the assessment of this pathology is fundamental to optimize the intensive culture of octopus.

Sentience in cephalopod molluscs: an updated assessment
Biological Reviews, Volume 101, Issue 3, Page 1311-1333, June 2026.ABSTRACT This article evaluates the evidence for sentience – the capacity to have feelings – in cephalopod molluscs: octopus, cuttlefish, squid, and nautilus. Our framework includes eight criteria, covering both whether the animal's nervous system could support sentience and whether their behaviour indicates sentience.
