Fig. 341. Branchial gill arch and columns, fissures branchiales in an embryo Shark (Callorhynchus antarcticus)

Norma lateralis.

(According to Schauinsland.)

On the ventral head section emerge: Nasengrübchen, eye, the I arcus branchialis, the mouth of the entrance is limited to the processus maxillaris and the mandibular arch. Behind him, the Arcus II or branchialis hyoid. The following is the fifth in decreasing size. In between are the fissures branchiales. On the IL and III. Arc are small warty elevations be-noticeably, the gill buds. The plant of the pectoral fin is elongated by one- or survey indicated the ventral Herzwulst lies with the heart. The highest point of the head is called the rostrum. He later moved into the area the nasal capsule. (See Figures 342) between the metencephalon and vesicle auditory neuromeres are visible.

Fig. 341. Kiemenbosen Arcus branchiales und Kiemenspalten, Fissurae branchiales

bei einem Embryo von Callorhynchus antarcticus. Norma lateralis.

(Nach Schauinsland.)


Am ventralen Kopfabschnitt treten hervor: Nasengrübchen, Auge, der I Arcus branchialis, der den Mundeingang begrenzt mit dem Processus maxillaris und dem Arcus mandibularis. Hinter ihm der II oder Arcus branchialis hyoides. Es folgen noch fünf in abnehmender Größe. Dazwischen liegen die Fissurae branchiales. Auf dem IL und III. Bogen sind kleine warzige Erhebungen be- merkbar, die Kiemenknospen. Die Anlage der Brustflosse ist durch eine läng- liche Erhebung angedeutet Ventralwärts liegt der Herzwulst mit dem Herzen. Der höchste Punkt des Kopfes heißt Rostrum. Er rückt später in den Bereich der Nasenkapsel. (Vergl. die Fig. 342.) Zwischen Metencephalon und Vesicula auditiva sind Neuromeren sichtbar.
