S. Lenz et al., THE EPIDERMAL LINES OF OCTOPUS-VULGARIS LAMARCK, 1798, AND SEPIOLA-AFFINIS NAEF, 1912 (MOLLUSCA, CEPHALOPODA) AT HATCHING STATE, Zoologischer Anzeiger, 234(2), 1995, pp. 145-157
Late embryonic stages and hatchlings of Octopus vulgaris Lamarck, 1798
, and Sepiola affinis Naef, 1912, have epidermal lines consisting of c
iliated cells and accessory cells, respectively. O. vulgaris shows 4 p
airs of bilateral symmetrical lines containing ciliated cells in the e
pidermis of the arms, the head and the mantle and one single line in t
he funnel epidermis. S. affinis has 5 pairs of bilateral symmetrical l
ines on the head, 4 on the arms and a band of ciliated cells on the fu
nnel. The epidermal lines of O. vulgaris show 2 different types of cil
iated sensory cells. The funnel line has a different structure. The ep
idermal lines of O. vulgaris and S. affinis correspond to the ones tha
t have already been described for Loligo vulgaris Lamarck, 1798, and S
epia officinalis Linne, 1758. They an regarded as an analogue of the l
ateral line system of fish.
