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.
Mauritius Island is 2000 km (1240 miles) southeast of Africa. It gives off a stunning optical illusion that the island its on top of a large waterfall. There actually isn't much of a depth difference at all, but the receding waves are pulling the light colored sand out into the ocean, giving the illusion of a drop off.
Turns out it wasn't the doing of aliens who'd overshot a Nebraska cornfield or out-of-work art students with scuba gear. No, it was a masterwork by an amorous and talented male Takifugu rubripes, the poisonous pufferfish eaten by only the bravest sushi connoisseurs.
Yoji found a series of small male fish working tirelessly, day in and night out, to craft these mate-attracting marvels using a single fin.
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
