Friday Squid Blogging: More Squids
This research paper shows that the number of squids, and the number of cephalopods in general, has been steadily increasing over the past 60 years:
Our analyses revealed that cephalopod abundance has increased over the last six decades, a result consistently replicated across three distinct life history groups: demersal, benthopelagic, and pelagic... This is remarkable given the enormous life-history diversity exhibited across these groups, which were represented in this study by 35 species/genera and six families. Demersal species, for instance, have low dispersal capacity (tens of km) and occupy shelf waters. Benthopelagic species also occupy shelf waters, but have moderate dispersal capacity (hundreds of km) largely facilitated by a paralarval phase. Pelagic species inhabit open oceanic waters and have high dispersal capacity (thousands of km) facilitated by both a paralarval phase and a mobile adult phase.
As usual, you can also use this squid post to talk about the security stories in the news that I haven't covered.
