This squid needs no introduction. Commonly known as the giant squid, Architeuthis are found around the world. It is unclear how many species there are in this genus, it ranges between 1 and 3 usually.

Trying to collect a list of references for people recently introduced to architeuthis when new documentaries or spottings make the news.

The Giant Squid, Architeuthis dux Steenstrup, 1857 (Mollusca: Cephalopoda): The Making of an Iconic Specimen - Full PDF
J. Ablett
In 2004 the Natural History Museum, London (NHM) acquired an 8.62m long specimen of the giant squid Architeuthis dux Steenstrup, 1857. Complete giant squid are rare in museum collections and the chance to obtain a live-caught specimen with the potential for molecular analysis was an amazing opportunity. Also it was, and still is, the largest fluid preserved specimen at the NHM and although the preservation and storage presented numerous challenges, the squid’s public appeal as well as its scientific value has exceeded all expectations. I aim to show here the importance of such a specimen for the Museum collection, the difficulties met and overcome in all stages of its curation, as well as the numerous ways in which the squid has been used. These include such areas as education, the arts, exhibition, fund raising and public outreach, and its importance for the cephalopod research community.
Improving data quality to build a robust distribution model for Architeuthis dux

  • Highlights
  • We estimate the potential distribution map of the giant squid Architeuthis dux.
  • We detect important environmental parameters and produce absences from AquaMap
  • We combine information using feed-forward neural networks.
  • Our model is the most similar to an expert drawn map respect to other models
  • Our approach is also applicable to other rare species.
The giant squid (Architeuthis) has been reported since even before the 16th century, and has recently been observed live in its habitat for the first time. Among the species belonging to this genus, Architeuthis dux has received special attention from biologists. The distribution of this species is poorly understood, as most of our information stems from stranded animals or stomach remains. Predicting the habitat and distribution of this species, and more in general of difficult to observe species, is important from a biological conservation perspective. In this paper, we present an approach to estimate the potential distribution of A. dux at global scale, with relative high resolution (1-degree). Our approach relies on a complex preparation phase, which improves the reliability of presence, absence and environmental data correlated to the species habitat. We compare our distribution with those produced by state-of-the-art approaches (MaxEnt and AquaMaps), and use an expert-drawn map as reference. We demonstrate that our model projection is in agreement with the expert's map and is also compliant with several biological assessments of the species habitat and with recent observations. Furthermore, we show that our approach can be generalized as a paradigm that is applicable to other rare species.
