Eledone cirrhosa Beak with muscles, false colors

The beak of the octopus Eledone cirrhosa resides in the central location of the arms, just beneath its head within the buccal mass. This beak is constructed from very thin chitin and measures approximately two centimeters in width. An update reveals a scientific paper detailing the buccal musculature of Octopus bimaculoides. Given that the beaks of these species are nearly identical, it's now possible to extrapolate the buccal musculature of Eledone cirrhosa from this discovery, paving the way for the next iteration of this model. Color coding is used to identify the different muscles: Green signifies the superior mandibular muscle. Yellow highlights the anterior mandibular muscle. Blue represents the posterior mandibular muscle. Purple denotes the lateral mandibular muscle.
