From: In situ recordings of large gelatinous spheres from NE Atlantic, and the first genetic confirmation of egg mass of Illex coindetii (Vérany, 1839) (Cephalopoda, Mollusca)

Figure 3

(1) Ålesund sphere sample (thawed): (A) Recently fertilized, elipsoid egg of Illex coindetii measuring between 1–2 mm in length (by eye). (B) Formalin fixated egg. Chorion length and width for one egg measured 1.13 and 0.91 mm, respectively, and the jelly envelope length and width were measured to 1.65 and 1.59 mm, respectively. (2) Arendal sphere sample: (A) Live embryos of Illex coindetii; 16 embryos measured width of 0.77 ± 0.047 mm and length of 1.15 ± 0.119 mm (from microscope pictures (collected 8 August). Black measurement sphere is 1 mm in diameter. (B) Arrangement of live embryos within the egg mass in the internal mucous matrix. (3) Søgne sphere sample (thawed): Seven developed embryos of Illex coindetii, of which five were measured, showing total length of 1.83 ± 0.139 mm (from microscope pictures). (4) Arendal sphere sample (thawed): Developed embryo measuring approximately 2 mm in length (by microscope) (collected 7 August).
