dorsal

That evening he was within a feather-weight's turn of abandoning his road to the nearest station, and driving across that elevated dorsal line of South Wessex which divided him from his Tess's home.

While crossing, I saw numerous whales belonging to the three kinds peculiar to the southern seas; the whale, or the English "right whale," which has no dorsal fin; the "humpback," with reeved chest and large, whitish fins, which, in spite of its name, do not form wings; and the fin-back, of a yellowish brown, the liveliest of all the cetacea.

Nor did he see the dorsal fin break surface and approach him from the rear.

Great slate-colored backs and high serrated dorsal fins shot up with a fringe of silver, and then rolled down into the depths again.

But it is conceivable that the now utterly lost branchiae might have been gradually worked in by natural selection for some quite distinct purpose: in the same manner as, on the view entertained by some naturalists that the branchiae and dorsal scales of Annelids are homologous with the wings and wing-covers of insects, it is probable that organs which at a very ancient period served for respiration have been actually converted into organs of flight.

He has a peculiar way of showing his dorsal hooked fin in swimming, which looks something like a Roman nose.

Newman did not hear his voice, but perceived that he presented the dorsal expression of a well-dressed Englishman.

Kidd could see the finger of the dial stand up dark against the sky like the dorsal fin of a shark and the vain moonlight clinging to that idle clock.

On each side of the lower surface, or foot, there is a broad membrane, which appears sometimes to act as a ventilator, in causing a current of water to flow over the dorsal branchiae or lungs.

A species of Synodus differentiated from its congeners by the following combination of characters: dorsal-fin rays 11 or 12 (rarely 11); anal-fin rays 11; total caudal rays 41-42; dorsal segmented caudal rays 9; ventral segmented caudal rays 10; dorsal procurrent caudal rays 12; ventral procurrent caudal rays 10-11; pelvic-fin rays 8; pectoral-fin rays 11 or 12; total vertebrae 47-49, modally 49; predorsal vertebrae 12 or 13; pored lateral-line scales 45-48; median predorsal scales 12 or 13; scale rows on cheek 4-6; eye large, 4.5-6.9% SL (16.7-24.7% head length [HL]); anterior nostril flap long, tapering distally and extending over posterior nostril when depressed, length of flap 2.7-4.9% HL; snout blunt in dorsal view; pelvic-fin length 21.6-25.2% SL.

Swimming is highly specialized through rapid oscillations of the dorsal fin (Breder & Edgerton, 1942; Ashley-Ross, 2002), the caudal fin being absent and the whole caudal region having lost its role in locomotion.

Analysis of variance of total dorsal scales within these two groups, paired with Duncan's Multiple Range Test, suggests that these three taxa represent three full species.
