Vitreledonellais a genus ofmesopelagicoctopods from the familyAmphitretidaewhich contains two species,[1]one of which is theglass octopus.
These octopods have the sucker on their arms arranged in a single series with the suckers widely separated from each other. The third left arm is hectocotylisedwith a spherical vesicle at the distal end and in males the other arms have suckers which are enlarged beyond theweb.The eye has strong lateral compression with a near rectangular shape in lateral view and with the width equal to the diameter of thelens.There is a ventral, blunt rostrum-like extension on the eye which contains iridescent tissue above the eye. The opening to themantleis broad, theradulais multicuspid and linear in form with the first and second lateral tooth each being unicuspid, which means that this species has a heteroglossan radula. The long and slender digestive gland is spindle-shaped and the stomach is positioned dorsally to the digestive gland.[2]
AmphitretusandBolitaenaare two other transparent, gelatinous pelagic incirrate octopods. Both of these genera differ fromVitreledonellain that the right third arm is hectocotylized and the radula is ctenodont (with comb-like individual teeth).
