  Pygmy Beaked Whale, Mesoplodon peruvianus at MarineBio.org
The pygmy beaked whale, Mesoplodon peruvianus (Reyes, Mead and Van Waerebeek, 1991), is one of the latest discovered and smallest members of the genus Mesoplodon, maximum known length is only 3.9 m with males thought to be slightly larger than females.
Pygmy beaked whales have moderately long beaks, and low triangular dorsal fins with slightly falcate (curved) or straight trailing edges with small, triangular, wide-based dorsal fins that are shaped like those of harbor porpoises.
Beaked whales are generally slender with a small dorsal fin placed towards the rear on the back.

  Beaked whale - Wikipedia, the free encyclopedia
The beaked whales are the second-largest family of Cetaceans (after the dolphins) and were one of the first groups to diverge from the ancestral lineage.
Baird's and Cuvier's Beaked Whales were subject to commercial exploitation off the coast of Japan; and the Northern Bottlenose Whale was extensively hunted in the northern part of the North Atlantic late in the 19th and early in the 20th centuries.
However there are now clear issues of concern: studies of stranded beaked whales show rising levels of toxic chemicals in their blubber (as a top-order predator they are, like raptors, particularly vulnerable to build-up of biocontaminants) and they frequently have ingested plastic bags (which do not break down and can be lethal).

 Mesoplodont whale - Wikipedia, the free encyclopedia
Longman's Beaked Whale (also known as the Indo-Pacific Beaked Whale) is also sometimes classed in the Mesoplodon genus.
Beaked whales are typically medium to large sized for toothed whales, 3 to 6 meters in length, but diminutive when compared with Bottlenose Whales and Giant Beaked Whales.
Gray's Beaked Whale is the exception and has numerous small and possibly functional teeth in the lower jaw.

 Glacier Bay Alaska - Whale Watching Tours with Fairweather Adventures
The humpback whales are frequently observed swimming and feeding close to shorelines along the southern coast of Alaska.
Baleen is a comb-like structure in a whale's mouth that acts as a filter during feeding, it hangs from the upper jaw.
Killer whale behaviors include: breaching (jumping out of the water), lobtailing (slapping their flukes on the water's surface), spyhopping (swimming vertically with their head partially out of the water), and pec-slapping (slapping their pectoral flipper on the water's surface).

 Mty Bay beaked whales
Their giant head is filled with spermaceti, a reservoir of high-quality oil-like wax for which the whales were relentlessly hunted for "whale oil." There is only a rude ill-formed lump for a dorsal fin and the skin is textured with wrinkles and ridges.
Compared to the 35-40 foot Baird's Beaked Whale and the 18-25 foot Cuvier's Beaked Whale, the various species of 8-15 foot beaked whales in the genus Mesoplodon are both mysterious and difficult to identify in the field.

There are several families of Odontoceti, or toothed whales, including sperm whales, pygmy sperm whales, beaked whales, river-dolphins (3 families) belugas and narwhals, dolphins and porpoises.
A similar toothed whale family is the Kogiidae family which includes the pygmy sperm whale and dwarf sperm whale which are significantly smaller than the sperm whale but share characteristics such as the spermaceti organ, the blunt head, and the distinctive narrow lower jaw.
Beaked whales may be rare or simply elusive but, generally, they live in deep water far from land and are rarely seen.

Whaling peoples today are a far cry from the industrial whalers of the past century, who slaughtered entire whale populations to feed a global demand for whale oil and bone.
Whaling communities are widespread, in many regions: the Arctic, the Caribbean, Europe, North America, Southeast Asia, and the South Pacific.
Other species (non-IWC whales) are hunted as well, and include the beluga, narwhal, Baird's beaked whale, pilot whale species, pygmy killer whales, false killer whalers, harbor porpoise, Risso's dolphin, and various other species of dolphins.

Another good indicator that beaked whales are not dining with their teeth is the propensity for barnacles to grow on the teeth of some species.
Male beaked whales evidently use those teeth as "jousting weapons." Additionally, some of these assorted marks appear to be battlescars left from shark and killer whale attack.
The beaked whale family actually contains enough species that it is considered to be the second largest whale family in the world.

Twenty seven whale and dolphin species (half the total species found in Australian waters) are found in the Great Australian Bight.
Most notably, endangered southern right whales migrates from their summer feeding grounds in the Antarctic to the warmer waters of the Bight for six months over winter to have their young and start the next generation - an activity critical to the survival of the species.
They were one of the first whale species to be hunted globally - with a sobering 45 000 killed in the first 40 years of hunting (1805-44).

 EPA: Federal Register: Small Takes of Marine Mammals Incidental to Specified Activities; Oceanographic Surveys in the ...
However, the association of mass strandings of beaked whales with naval exercises and, in a recent case, an LDEO seismic survey has raised the possibility that beaked whales may be especially susceptible to injury and/or stranding when exposed to strong pulsed sounds.
In March 2000, several beaked whales that had been exposed to repeated pulses from high intensity, mid-frequency military sonars stranded and died in the Providence Channels of the Bahamas Islands, and were subsequently found to have incurred cranial and ear damage (NOAA and USN, 2001).
A recent workshop (Gentry (ed.), 2002) was held to discuss whether the stranding of beaked whales in the Bahamas in 2000 might have been related to air cavity resonance or bubble formation in tissues caused by exposure to noise from naval sonar.

Issues and threats: Commercial whaling, especially before it was regulated, hunted down whales almost to extinction (as one species became scarce, another one was quickly chosen to take its place).
Not counting the dolphins, there are 11 whale species that have been confirmed present in Philippine waters, a report from Silliman University indicates.
Humpback whales have been hunted to near extinction, and only a few thousand are believed to survive today.

Mexico has decreed a Mexican Whale Sanctuary in all of its EEZ (exclusive economic zone) in the Pacific Ocean, Atlantic Ocean and Caribbean Sea οΎ– an area of approximately three million square kilometres.
One of the offshoots of the campaign was the modification of the Wildlife Law in 2000 to forbid all whaling in Mexico for commercial or subsistence purposes, and the listing of all cetaceans as needing special protection.
The fact that it was created during the week that the IWC meeting took place in Shimonoseki, Japan is a message to the entire world that Mexico is against whaling.

As with all beaked whales, identification at sea based on current knowledge, is dependent upon observation of the head.
Sowerby's Beaked Whale is restricted to the northern North Atlantic, with the majority of sightings being at latitudes between the Canary Islands and the Arctic Circle.
The status of Sowerby's Beaked Whale in the European Atlantic remains poorly known, but these few records suggest that it is the most frequently occurring Mesoplodon species in the region.

Whether you find your fluke images on WhaleNet, use the Voyage of the Mimi, adopt a humpback whale, or photograph a whale on a whale watch, you may want to photo-identify the individual.
Record photo-identification photographs of whales taken on the cruise, as follows: date, location (lat/long), photographer's name, roll number (label each roll of film with the initials of the photographer and roll number such as: JMW/95-001), and picture number.
If your classroom is not going on a whale watch trip but is instead using whale watch data from WhaleNet's data base, use the data sheets to copy data out of the WhaleNet archives.
