When the scallop’s shell is gaped you can see two rows of tiny, bright blue eyes. These eyes aren’t the simple light sensitive eyes that most mollusks have, they can also sense motion. So a crab or fish trying to sneak up on one and grab some flesh before the shells close will be seen before it gets even close. And if the scallop loses an eye it simply regenerates a new one in its place.
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.
