So many limbs, so little anything else

My original post was kindly corrected by Dr. Bonnie Bain, who pointed out that the secretions- mainly emitted by cement glands on the femurs- the eggs were wrapped in were probably not mucus, but no one has investigated the material in depth. Dr. Bain’s paper has a lot of other interesting details about the mating of the sea spiders (pycnogonids), including some fascinating descriptions of courting behavior, and aggression between females for mates.
