Interorbital

"Delay for interorbital transmission," said the Hosaka. ❋ Boudreau Freret (2010)

These are entirely unaffected by the torsion of the interorbital part of the skull. ❋ J. T. Cunningham (1897)

Anatomical investigation shows that the bony interorbital septum composed principally of the frontal bones, which in symmetrical fish passes between the eyes, is still between the eyes in the Flat-fish, but has been bent round through an angle of 90 degrees on the upper side, while in the lower side a new bony connexion has been formed on the outer side of the eye which has moved from the lower side. ❋ J. T. Cunningham (1897)

This independence is well shown in the modification of the dorsal fin: if this were physiologically affected by the change in the eyes, which is brought about by the twisting of the interorbital region of the skull, the anterior end of the fin would be between the two eyes, since the morphological median line of the body is in that position. ❋ J. T. Cunningham (1897)

The upper and anterior cavity of the three into which the skull may be divided, is the one which is so greatly modified; it is evidently much larger than in the Cochin skull of the same size, and extends much further beyond the interorbital septum, but laterally is less deep. ❋ Charles Darwin (1845)

Ancistrus agostinhoi is distinguished from congeners in the region by a combination of: shorter maxillary barbel that is not distinctly produced from the lower lip margin, width of mandibulary tooth rows 15. 8-19.3% head length and 38. 4-53.6% interorbital width, eye diameter ❋ Unknown (2009)

(unpigmented) patch of membrane at the hind end of the anal fin, pale grey anal fin, 4-5 arrow-head shaped teeth at the front end of the lower jaw, body depth 6. 3-10.2% total length, mouth width 35. 5-52.5% head length, interorbital distance 37. 9-49.2% head length, head depth ❋ Unknown (2010)
