### animal | vertebrate | mammal | whale | narwhal:

Male narwhal
* Most male narwhals attain maturity
* Most male narwhals have straight teeth
* Most male narwhals possess spiral teeth
* Some male narwhals have long tusks
  - single tusks
* are easy to identify because of their long, ivory tusks.
* possess a great spiraled tooth that projects from their heads

Newborn whale
* are already about one-quarter their mothers length.
* have the innate ability to swim.

Orca whale
* Some orca whales have predators.
* are the largest members of the dolphin family.
* feeds on seals, squid, great whales, penguins and walruses.
* have white bodies with dark dorsal, upper body, fins.

Resident whale
* are fish eaters and make good use of their echolocating clicks.
* eat mainly fish but transient whales eat seals, penguins, and other whales.
* tend to be noisy while transient whales hunt silently.

### animal | vertebrate | mammal | whale:

Right whale
* Most right whales rely on temperature.
* are baleen whales, they filter their food through their long baleen plates
  - difficult to spot because of their dark color and low profile in the water
  - large, rotund, black whales with large heads, long rostrums, and no dorsal fins
  - quite rare to see and are physically very different from other species of whale
  - similar to bowhead whales , but smaller
  - skimmers, filter feeders that swim slowly with their mouth open, constantly eating
  - slow swimmers, averaging just six miles per hour
  - so rare that many people fear that they are doomed to extinction
  - stocky, slow-swimming whales that carry a rich supply of oil
  - unaware of vessels, particularly when engaging in feeding or sexual activity
* come to bear their young and breed.
* die from collisions with ships and entanglement in fishing gear
  - of natural causes and are sometimes preyed upon by killer whales
* eat copepods primarily
  - small invertebrates called krill and copepods, which live in fairly shallow water
* feed exclusively on tiny plankton, which occur in very dense swarms during the spring
  - mainly on copepods but also consume krill and pteropods
* have a low bushy spout
  - low, bushy blow
  - at least six distinct calls, each related to a specific function
  - distinctive vocalizations, as do all marine mammals
* have no dorsal fin and no throat grooves
  - the finest of all baleen fringes and specialize in eating the smallest plankton
  - two separate blow holes, creating a distinctive v-shaped blow
* live in temperate and cool seas in both hemispheres at the surface of the ocean.
* make a variety of vocalizations.
* occur close to shore, and in areas in or adjacent to major shipping lanes.
* open their great mouths and graze along the surface of the water.
* produce a distinctive V-shaped blow.
* remain among the rarest of marine mammals.
* reside in shallow waters that border islands and coastlines.
* seem to eat mostly, perhaps, only plankton
  - show a preference for certain species of zooplankton, especially copepods
* show distinctive social behaviors - nuzzling, bumping, and rubbing against each other.
* spend much of their time at the surface, feeding, resting, mating, and nursing.
* swim along the surface open-mouthed, skimming the water with long baleen
  - close to shore and in areas in or adjacent to major shipping lanes
+ Right whale, Description
  * Right whales are similar to bowhead whales, but smaller. These whales are rich in blubber and have 2 blowholes. The eyes are very small and lips are large.

Rorqual
* Most rorquals mate in warm waters in winter to give birth almost a year later.
* have a broad, flat rostrum and a slightly curved jawline.

Rorqual whale
* feed by gulping large concentrations of crustaceans and schooling fishes.
* have the pleated throat grooves that enable massive gulping of water.
