North Pacific Right Whale Description
  They have large pectoral flippers and broad tail flukes, but no dorsal fin. Their head is often covered in white callosities – small, irregular patches of “callused” skin which are covered in harmless “whale lice”. The pattern of callosities is unique to individuals and allows individual identification, which has been very useful in establishing population numbers in the North Atlantic right whale population. Similar to rorqual whales (such as humpbacks and blue whales), right whales have baleen, “horny plates” in place of teeth that are used to sieve out food from the water. However, they do not have the ventral pleats, the expanding “accordion” structure – allowing a rorqual whales to take large mouthfuls of water (and thus more food) and are, therefore, more closely related to the grey and bowhead whales.
