How do pilot whales reproduce?
Like all mammals, long-finned pilot whales reproduce via internal fertilization and give birth to live young, which they nurse for more than two years. Mating can be somewhat rough, involving biting, head butting, and other aggressive behaviors.
How often do pilot whales reproduce?
Mating and Breeding Gestation lasts approximately 12 to15 months and calving occurs once every 3 to 5 years. Calves are generally 6 feet (1.8 m) at birth, and weigh about 225 pounds.
Where do pilot whales breed?
They are commonly found along the coast close to the continental shelf, although some populations have been found to extend into deep, open ocean environments such as in the eastern tropical Pacific Ocean. Pilot whales are often involved in mass strandings for reasons that are still unclear.
How many pilot whales are in a pod?
20-100 whales
Each pod numbers 20-100 whales, though they can congregate in much larger numbers. Very little is known about the life history of long-finned pilot whales in the Southern Hemisphere.
Do pilot whales hunt sperm whales?
Orcas are the largest natural threat to sperm whales, though pilot whales and false killer whales are also known to hunt them.
Are long-finned pilot whales endangered?

How long can pilot whales stay underwater?
Long-finned pilot whales can dive to depths of about 2,000 feet for 10 to 16 minutes to feed on fish (e.g., cod, dogfish, hake, herring, mackerel and turbot), cephalopods (e.g., squid and octopus) and crustaceans (e.g., shrimp).
How long do pilot whales live?
Short-finned pilot whale: 45Â yearsPilot whales / Lifespan
Are pilot whales endangered?
What is a group of pilot whales called?
Both species live in groups of 10–30, but some groups may number 100 or more. Data suggest the social structures of pilot whale pods are similar to those of “resident” killer whales. The pods are highly stable and the members have close matrilineal relationships.
Are pilot whales and false killer whales the same?
False killer whales are closely related to, and easy to confuse with pygmy killer whales, melon headed whales, and pilot whales, particularly young pilot whales. Pilot whales can be distinguished from false killer whales by their bulbous heads and more foreword-placed and broader and rounded dorsal fins.
What type of animal is a long finned pilot whale?
The long-finned pilot whale (Globicephala melas) is a species of oceanic dolphin. It shares the genus Globicephala with the short-finned pilot whale (Globicephala macrorhynchus).
How long does it take for a pilot whale to mature?
In the summer and autumn, long-finned pilot whales generally follow their favorite foods farther inshore and on to the continental shelf. World map providing approximate representation of the long-finned pilot whale’s range. Males become sexually mature at 12 to 13 years and females at 8 years.
What is the difference between a long finned and short finned whale?
Long-finned pilot whales are one of two species of pilot whale, along with short-finned pilot whales. In the field and at sea, it is very difficult to distinguish the two species, which differ only slightly in physical size, features, coloration, and pattern.
Where do long-finned pilot whales live?
Long-finned pilot whales are found in the North Atlantic, as well as the Southern Hemisphere.
