Squid, it seems, may be among the most vulnerable, with consequences that could trickle through the marine ecosystem. A new study published May 31 in the journal PLOS ONE finds that squid raised in more highly acidified ocean water hatch more slowly and are smaller when they hatch than squid raised in ocean water at today's pH levels. The acid-exposed squid also have abnormal statoliths, which are internal, calcified structures that function like the mammalian inner ear to help squid keep their balance and orient themselves.
With its gaping mouth, needle-sharp teeth, and slightly startled expression, the black sea devil anglerfish seems tailor-made for the spotlight.
And in fact, one particular female got her close-up on November 17 when researchers got footage of this rare anglerfish—the first time this species has been filmed alive and in its natural habitat—off of central California
