Extreme plasticity in life‐history strategy allows a migratory predator (jumbo squid) to cope with a changing climate
Hydro-acoustic data, reveal that squid biomass in this study area nearly doubled between 2010 and 2011, primarily due to a large increase in small squid that were not susceptible to the fishery, indicating a climate-driven switch in size-at-maturity may allow D. gigas to rapidly adapt to and cope with El Niño.
Reproductive biology in two species of deep-sea squids
The data and the literature data show that the so-called “synchronous ovulation” probably occurs in all deepwater squids.
Reproductive system of the giant squid Architeuthis in South African waters
The reproductive system is described from 15 giant squid Architeuthis sp., collected between 1972 and 2002 in South African waters. Distinctive features of the mate reproductive system are the long…
Spermatophore implantation in Rossia moelleri Steenstrup, 1856 (Sepiolidae; Cephalopoda)
Reproductive system and the spermatophoric reaction of the mesopelagic squid Octopoteuthis sicula (Rüppell 1844) (Cephalopoda: Octopoteuthidae) from southern African waters
Reproductive features of the poorly known oceanic squid Octopoteuthis sicula are described and quantified to gain insight into the reproductive biology of the species and shows female-biased sexual size dimorphism.
Vampire squid reproductive strategy is unique among coleoid cephalopods
Getting Under the Skin: Autonomous Implantation of Squid Spermatophores
Here, through on board observation of freshly caught deep-sea squid, it is shown for the first time that spermatophores have an autonomous mechanism that enables them to migrate into body tissue.
TuLUMIS - a tunable LED-based underwater multispectral imaging system.
A novel underwater MSI system based on a tunable light source is presented which employs a monochrome still image camera with flashing, pressure neutral color LEDs, and showed the first evidence that the system is capable of acquiring useful imagery under real marine conditions.

Some potential costs and benefits of post-spawning egg care are presented, a strategy that is now known for two families of deep-dwelling squids, but may turn out to be more common with the increasing exploration of the deep sea.

A newly discovered organ in the swordfish head, consisting of an oil-producing gland connected to capillaries with oil-excreting pores in the skin, may reduce streamwise friction drag and increase swimming efficiency.
