Mantle Cavity

The males have a duct in under the oesophagus, extending from the mantle-cavity to the lower portion of the sac, and there is an organ to which it attaches, resembling a breast; (see diagram) in the female there are two of these organs, situated higher up; (see diagram) with both sexes there are underneath these organs certain red formations. ❋ Unknown (2002)

In certain male cuttle-fishes, in the breeding season, one of the arms develops in a curious fashion into a long coiled whip-lash, and in the act of breeding may then be transferred to the mantle-cavity of the female. ❋ Various (N/A)

Both kinds of cells pass first into the mantle-cavity after the opening of the gonads, proceed through the gill-clefts into the branchial gut, and are discharged from this through the mouth. ❋ Ernst Heinrich Philipp August Haeckel (1876)

If we open the thick tunic or mantle in order to examine the internal organisation, we first find a spacious cavity filled with water -- the mantle-cavity or respiratory cavity ❋ Ernst Heinrich Philipp August Haeckel (1876)

The respiratory water now passes from the gut-cavity (D) into the mantle-cavity (A). ❋ Ernst Heinrich Philipp August Haeckel (1876)

The ripe ova (Figure 2.221 o apostrophe) fall directly from the ovary (o) into the mantle-cavity. ❋ Ernst Heinrich Philipp August Haeckel (1876)

Although we can find afterwards no continuation of the body-cavity (Figure 2.216 U) in the lateral walls of the mantle-cavity, in the gill-covers or mantle-folds ❋ Ernst Heinrich Philipp August Haeckel (1876)

A mantle-cavity, K gill-clefts, b = E epidermis, E1 the same as visceral epithelium of the mantle-cavity, E2 as parietal epithelium of the mantle-cavity.) ❋ Ernst Heinrich Philipp August Haeckel (1876)
