Right Whale
Table of Contents
A right whale is one of the three species of baleen whales belonging to the genus Eubalaena. This species is one of the largest on Earth, after blue whales and bowheads. These whales have distinctive skin patches, are docile and prefer shallower waters near shorelines.
There are 3 species of these whales that belong to the genus Eubalaena. Their popular name comes from whalers which said that this is the right type of whale to hunt due to their docile nature, large amount of blubber and coastal tendencies. Eubalaena glacialis is the North Atlantic whale, E. japonica is the North Pacific whale and E. australis the Southern whale. The species belong to the family Balaenidae alongside bowhead whales.
These whales are large with a robust head. They present distinctive callosities or rough patches of skin mostly on the head, with distinctive patterns. These are actually caused by whale lice that are actually parasitic crustaceans. The patterns are unique to each whale and so they are helpful for scientific studies.
An adult right whale may measure between 11 and 18 meters in length, with typical lengths ranging from 13 to 16 meters. The body is compact with a girth of up to 60 percent of the length. Contrary to most other baleen whales, they do not have a dorsal fin. These whales can weigh up to 90 tons, with males having the largest and heaviest penises being 2 meters long and weighing 500 kilograms. The baleen plates can be around 200 or 300 and they are usually about 2 meters long.
These whales are filter feeders. They swim at very low speeds with their mouth open, filling it with large amounts of water as well as zooplankton rich in crustaceans such as copepods or krill. With the help of the baleen plates, the whale expels all water and retains the prey which they then swallow through an opening that is smaller than a beach ball. The whales search for waters that have enough prey which must be large enough to be retained by the baleen plates as well as slow enough to be unable to escape, being that these whales are very slow swimmers with a top speed of less than 10 kilometers per hour.
These whales prefer colder waters and thus the warm equatorial waters prevent the Northern species to mix with the Southern ones. In the North Atlantic, mating seasons have been observed throughout the year. There are usually groups of up to 20 males which typically surround just one female. She sits with the belly up and the males stroke it with their flippers. These males do not exhibit the aggressive behavior of humpback whales. Females breed once every three of four years. They give birth after a gestational period of about one year. Calves are 4 to 6 meters long and weigh almost a ton. The calf will double its length within the first year of its life. The oldest known right whale was 70 years old, but some individuals may live far longer.
The Majestic Journey of the Right Whale: Understanding a Marine Giant
The Right Whale, named for being the ‘right’ whale to hunt due to its slow speed and tendency to float after being harpooned, is a majestic creature of the deep that has fascinated humanity for centuries. This article delves into the life of these gentle giants, exploring their biology, behavior, and the conservation efforts that are crucial for their survival.

Introduction
The ocean, a vast and enigmatic expanse, is home to an incredible diversity of life. Amongst the most awe-inspiring of marine creatures is the Right Whale. Known for their massive size, distinctive callosities, and rich history intertwined with the whaling industry, these whales have captured the attention of scientists, conservationists, and the public alike.
Anatomy and Physiology
Right Whales are baleen whales, possessing baleen plates for filtering food from water rather than teeth. Their robust bodies, which can grow up to 60 feet in length and weigh upwards of 100 tons, are supported by a blubber layer that provides insulation and energy reserves. A distinguishing feature of the Right Whale is the presence of callosities, roughened patches of skin that are habitat for whale lice, giving each whale a unique pattern for identification.
Behavior and Social Structure
The social dynamics of Right Whales are complex and fascinating. They are often seen engaging in surface-active behaviors, such as breaching and tail slapping, which are believed to be forms of communication. These whales are generally solitary but can be observed in small groups, especially during the breeding season, when their haunting calls echo through the ocean.
Habitat and Migration Patterns
Right Whales inhabit the cooler waters of the North Atlantic and North Pacific, with distinct populations that rarely, if ever, intermingle. Their migratory patterns are dictated by feeding and breeding needs, traveling thousands of miles from feeding grounds in the higher latitudes to warmer waters for calving and mating.
Diet and Feeding Habits
These leviathans feed primarily on zooplankton, including copepods and krill. They consume these tiny creatures through a method known as skim feeding, swimming with their mouths open to filter food through their baleen plates.
Conservation Status and Efforts
The Right Whale is currently classified as endangered, with their numbers having been severely depleted by commercial whaling. Today, they face threats from ship strikes, entanglement in fishing gear, and habitat degradation. Conservation efforts include protective legislation, modifications to fishing practices, and extensive research to better understand and mitigate the impacts of human activities on their populations.
Conclusion
The Right Whale is an iconic species that plays a critical role in our marine ecosystems. It is our responsibility to ensure their survival, not only for the health of our oceans but for future generations to marvel at their grandeur. Through concerted conservation efforts and a commitment to sustainable ocean practices, we can turn the tide for these magnificent creatures.
