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.

Penis fencing

Most flatworms are a little more chill about mating.

Needlessly complex

There is a LOT of debate about why genital structures are so varied among species. SO MUCH DRAMA.

size matters

I’m guessing they pheromones to find their mates, but I like to imagine a large rock covered in barnacles, little penises emerging from all of them, feeling around like long thin little fingers.

They do have long proboscises, tho.

These poor worms in phyla Priapulida mate through external fertilization.

mucus cuddle

This is my favorite penis fact, by far. Such a cute little slug mucus cuddle.

The little death

I did my best to draw this honey bee penis, but honestly I have no idea how well I did.

A little too stabby

These little slugs are TINY. Like just a few mm long.

The stylet also inserts something into the other slug that increases it’s fertility.
