Apart from the specific species that they were targeting during the hunt, whalemen were generally poor observers of wildlife. Sperm whales, right whales, bowhead whales, their habits, habitats and general appearance were commonly understood at a commercial level but only a few whalemen made any attempt to systematically identify other species of whales or small cetacea. Blackfish (Globicephala melas, the long-finned pilot whale) are an exception as these were also frequently hunted and whalemen had the opportunity to observe both their behavior and anatomy closely.
At the very least whalers were inconsistent in whatever observations they may have made. This is not to say that whalemen didn’t see an astonishing array of the world’s species, just that their interests were almost wholly commercial and only rarely systematic. The whales, birds and other cetaceans illustrated and described in Purrington & Russell’s Grand Panorama of a Whaling Voyage Round the World are no exception. Obviously, frequent mentions are made in seamen’s logbooks and journals noting a wide variety of birds, fish and whales but seldom are these animals illustrated, and even more rarely are they either named or described in any useful way. Vernacular, seemingly random, and completely unsystematic terms are commonly employed to which none but a whaler can relate.
For instance, this particular scene in the Panorama is described in the handbill text as “brig in a school of porpoises.” By no stretch of the modern imagination could the animals painted in this scene be described as “porpoises,” yet whalemen commonly applied the term to any number of small cetaceans. Modern descriptions of the porpoises (Phocoenidae) describe them as small, blunt-headed and coastal; “preferring to keep to themselves, porpoises are typically shy creatures and rarely perform the acrobatic feats of dolphins.” The only species of porpoise common to the Cape Verde archipelago is the harbor porpoise, (Phocoena phocoean) a small, blunt-nosed creature. However, even with their pointed snouts, a hint of a dorsal fin, a large aggregation and fairly acrobatic portrayal of behavior, one would be hard-pressed to say what exactly Purrington and Russell intended these animals to be.
They are obviously some type of cetacea, probably of the dolphin tribe, possibly of the sort called “algerines,” or “algerine porpoises” by the whalemen. The animals in the picture also greatly resemble members of the beaked whale tribe of the sort sometimes called the “grampus” by whalers. The region where this scene took place was in the North Atlantic Ocean off the Cape Verde Islands. These waters are home to a wide variety of oceanic dolphins (Delphinidae) however current habitat projection maps do not suggest that any species of beaked whales (Ziphiidea) live in the vicinity of the Cape Verde Islands. Recent observations (2010, 2014) have placed small groups of at least two species of beaked whale, Cuvier’s beaked whale (Ziphius cavirostris) and Gervais’ beaked whale (Mesoplodon cf. europaeus) around the waters off Cape Verde, but these are confirmed as rarities. Dolphins are another matter. Bottlenose dolphins, common dolphins, spotted dolphins, striped dolphins and spinner dolphins all live in these waters, are socially gregarious and acrobatic in their behavior. That, combined with the use of the whaler’s term “porpoise” suggests that these animals are probably dolphins.
One solid advantage to the relational usage of the term “porpoise” is that most whalemen used the term to describe the multitudes of dolphins encountered in large schools on the high seas. Further, as beaked whales seldom congregate in social schools gamboling about in the waves, the likelihood is very strong that Purrington and Russell accurately described the behavior of a school of dolphins.
Probably the best single synopsis of whalemen’s vernacular language describing the various whales and small cetaceans encountered is from Moby-Dick. A selection of these can be read in Chapter 32, “Cetology, ” with the following caveats:
- There was at the time of its writing considerable inconsistency in the naming of cetacean species and popular language swapped around between actual species as far as Linnaean nomenclature could identify them and mariner’s usage.
- Melville as a whaleman himself adopted whalemen’s usage.
- Melville was mocking the books of science written by persons with no firsthand knowledge of what it was they were describing.
He writes in the first part of that chapter: “of real knowledge there be little, yet of books there are a plenty.” He then goes on the arrange his classifications and subdivisions similarly to the table of contents of Robert Hamilton’s “On the Ordinary Ceacea, or Whales,” in William Jardine’s Naturalists Library, as well as John Hunter’s “Observations on the structure and œconomy of whales” in Philosophical Transactions of London (June 28, 1787); that is Roman numeral, genus, species. Being the satirist that he was though, instead of even attempting to sound “scientific,” Melville makes up these foolish categories of whale species compared to the sizes of books, presumably representing the varieties in size of the very books he consulted, hinting that books are the sole source of knowledge of cetacean, and that whalemen, while seeing most of the animals in question could not properly identify most of them. Dolphins and porpoises are not distinguished and just because Melville calls it a porpoise does not mean that it is one. Numerous whaling references, including early 20th century photographs identify dolphins as porpoises and we know that whalers lowered for dolphins as well as harpooned them from the bows of the ship for food.
Sulphur bottom – Undoubtedly Balænoptera musculus (Blue whale) as verified in Charles M. Scammon’s Marine mammals of the Northwestern coast of North America (San Francisco, 1874) and Hershkovitz, Catalog of Living Whales (Washington, 1966). The “Great Northern Rorqual” of Jardine/Hamilton (PH 5190-A) is derived from the two 1827 prints of the blue whale that stranded at Ostend, Belgium which was in large measure copied in 1832 for another print.
Killer/Thrasher – Undoubtedly Orcinus orca. In the text of Jardine/Hamilton under the entry for “The Grampus” is the following: “Finally it is the fish which the Americans have long been in the habit of denominating the killer or thrasher, from its reputed pugnacious and cruel disposition.”
As this entry mentioning “thrasher” serves as the only reference that I have ever seen (including logbook and journal references to killers) I suspect that Melville either legitimately heard this phrase used in the fishery or, what is more likely, borrowed it from Jardine/Hamilton. Please note that Melville separates “killers” from “grampus.” What was meant by the whalemen’s term of “grampus” is difficult to determine. Sometimes in the whalemen’s writings it seems to refer to the killer or orca, other times, the killer is distinct and the grampus is also distinct. Jardine/Hamilton’s illustration of “The Grampus” is obviously an orca. Grampus griseus or Risso’s Dolphin is the only official appearance of the term grampus. The only actual illustration of the grampus of whalemen’s parlance is from KWM #1033, a journal kept by seaman Daniel C. Whitfield onboard the bark Dr. Franklin of Westport, 1856-1859. It is obviously a beaked whale of some kind.
Huzza porpoise – Probably Lagenorhynchus obliquidens of Scammon, the striped or common porpoise. Scammon’s text description coincides well with Melville’s the difference being that Melville claims that they are found “almost all over the globe,” whereas this particular animal is a Pacific species. Apart from that the striped dolphin or common dolphin is the most likely candidate being gregarious and global.
Algerine porpoise – Completely unidentifiable. Whaling logbooks and journals frequently mention them although they are seldom illustrated (ODHS#572, September 22, 1859). Chances are good that they are one of the many species of larger dolphins, such as Tursiops truncatus, the bottle nose dolphin.
Mealy-mouthed porpoise – Undoubtedly the Southern right whale dolphin, Lissodelphis peronii .
While the bulk of American whalemen did not record their observations of sea creatures, some did. Those few who did actually identify species in a useful fashion have contributed some important clues to understanding the prolific life of the oceans. Purrington & Russell’s Grand Panorama was intended to be educational entertainment, but for all that, it serves today as an important document serving to offer insights into the world as witnessed by American mariners. Whether or not the artists captured the true nature of marine life, they absolutely captured the significance of the American whalemen to the growing understanding of the world and its seas in the 19th century.
 Thomas Beale, The Natural History of the Sperm Whale (Edinburgh, 1839); William Scoresby, An Account of the Arctic Regions (Edinburgh, 1820); Charles Melville Scammon, The Marine Mammals of the Northwestern Coast of North America (San Francisco, 1874) are notable exceptions. These books, written by whalemen are all superb natural history texts, illustrated accurately with a wide variety of species and other documentary pictures. The average whalemen produced nothing even remotely as insightful as these.
