STARFISH WITH BABIES, BROODING BEHAVIOR REVEALED
ChrisM/ The equino blog
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!
