UPDATE ON RECENT SQUID ACTIVITY
The squid we've been seeing on the beaches in Wellfleet and Provincetown are shortfin squid (Illex illecebrosus), also known as summer squid.
These are different from the longfin squid (Doryteuthis/Loligo pealeii) that we think of as common in inshore waters and which are jigged in harbors by fishermen.
The phenomenon of large numbers of summer squid on beaches is not a new one, but it's one we haven't seen often in recent years (2017 was a recent exception) It was a more frequent occurrence in the 1970s and 80s.
We’re not sure why it happens, but suspect it’s related to a combination of predator/prey interactions, wind/tide, and local abundance of this oceanic squid species.
