Idiosepius paradoxus Spermatophore Delivery | Pygmy Squid

Male Japanese pygmy squids (Idiosepius paradoxus) like the darker squid on the right side of this image often approach females in the process of depositing eggs to pass on spermatophores. Pictured here is the moment that this male has just offered the white strands of sperm. The female has indicated that she will accept. Spermatophores that she has previously received from other males are visible attached to her mantle.
