REVIEW OF THE SYSTEMATICS AND ECOLOGY OF OCEANIC SQUIDS 259
TABLE IV. MAXIMUM MANTLE LENGTHS RECORDED FOR THE SPECIES IN
EACH FAMILY.
Under each family heading is the number of species having a recorded
maximum length in each size group
* Not included in totals.
there are basically three types : in Histioteuthis bonellii and Calliteuthis
reversa virtually no change in form takes place and growth can be
regarded as isometric above a mantle length of 3-0 cm ; in Chiroteuthis
veranyi, Lepidoteuthis grimaldii, Galiteuthis armata, Onychia carribaea
and possibly Ctenopteryx sicula there is no “change of direction ” in the
growth of the selected structures. That is, the structure either grows
longer or shorter, broader or narrower throughout life (within the
size limits of the specimens) ; in Thysanoteuthis rhombus, Brachioteuthis
riisei, Todarodes pacijicus, Ancistroteuthis lichtensteinei, Gonatus
