Info
Neosmilaster georgianus is one of the most common sea stars in Antarctic waters.
Adult specimens reach a radius of about 5-7cm.
Neosmilaster georgianus populations are reproductively active throughout the year. Prior to spawning, the male mounts the female as a pseudocopulatory behavior.
In this way, the probability of fertilization is increased.
This is a breeding species, and the young are kept in a suboral brood chamber for several months to more than a year.
During this time, feeding and movement of the adult starfish are restricted or even inhibited.
The Arctic feeds on small invertebrates and is also an opportunistic scavenger of organic detritus.
This species occurs off the Palmer Archipelago, South Georgia, the South Sandwich Islands, and the South Shetland Islands and is often seen on exposed surfaces.
