In this large species, the adult male attains a length of about thirty 
feet, the female being considerably less. The head is broad and rounded, 
the jaws contain about twelve pairs of formidable curved teeth, and the 
whole body is very robust. The most striking feature in this whale is 
the enormous development of the flippers and dorsal fin in some of the 
old males. In Sir Sidney Harmer's Report on Cetacea Stranded on the 
'British Coasts during 1916, mention is made of one found in the Solway 
Firth whose dorsal fin measured no less than 5 feet 6 inches in length, 
the pectoral fins 6 feet 8 inches in length and 3 feet 7 inches in breadth, 
the flippers being larger than those in an adult male Sperm Whale. 
The flukes of the tail are also very broad and strong. 
The upper parts are glossy black in colour, with an elongated white 
patch extending backwards from just above the eye. The chin, throat, 
and belly are pure white ; this colour is carried upwards in the form of 
a well defined lobe which overlaps the black on the sides of the animal. 
Behind the great dorsal fin, which stands erect in the middle of the 
back, is a grey or purplish saddle mark extending across the body in 
the form of a crescent. The Killer ranges far through the Atlantic and 
Pacific Oceans, from the Arctic ice floes to those of the Antarctic. 
It often visits the British coasts in summer, especially the more northern
