Vampire Squid from E/V Nautilus in the Gulf of Mexico
"Here’s video of the vampire squid (Vampyroteuthis infernalis) encountered by Nautilus Live on June 27, 2014, in the Gulf of Mexico. This deep-sea cephalopod gets its name because of its deep color and red eyes, not because it feeds on blood.”
STARFISH WITH BABIES, BROODING BEHAVIOR REVEALED
This motherly starfish is taking care of her starbabies. Some starfish species, such as this one Diplasterias brandti, brood and carry their babies until they are ready to leave the nest, just like some vertebrate species.
SEVERAL different species of sea stars brood. Almost all of them are either cold-water species, living in the deep-sea or at the poles. Sometimes brooding is in temperate water species.. But typically not in the tropics.
Brooding also takes different forms. The oral ‘mouth’ or gastric brooding mode is but one kind. Here is Diplasterias from the Antarctic! MANY starfish in the Antarctic brood juvenile starfish!

Dolphins Talk to Each Other Using Personal Names
Scientists at the Univ. of St Andrews have shown that bottlenose dolphins can use copying of signature whistles as a way of addressing or labeling animals on an individual basis.
The research was carried out by marine biologists Stephanie King and Vincent Janik who conducted sound playback experiments with wild bottlenose dolphins on the east coast of Scotland.

DNA Sheds Light on Rare Killer Whale Type
by Megan Gannon
Scientists have long suspected that the killer whale, Orcinus orca, may actually be four different species or subspecies based of subtle differences in appearance and variations in behavior. The rarest of them all is known as type D. These fat-headed orcas, marked by tiny white patches around their eyes, were only recently observed in the wild, some 50 years after they were first identified in photographs from a mass stranding in New Zealand.
The skeleton of one of the type D whales that washed ashore in 1955 ended up at a museum in Wellington. In a new study, scientists analyzed DNA from the bones, showing, yes, type D is likely a distinct subspecies or species. The research, detailed in the journal Polar Biology, also suggests type D diverged from other killer whales about 390,000 years ago, making it the second oldest orca type…
