Blue Whale Vs Sperm Whale
Blue Whale or Balaenoptera Musculus is a large marine mammal under the suborder of Baleen Whale (Mysticeti). Blue Whale is the largest animal that is alive, and it grows to the length of more than 100 ft long as well as weighing more than 150 tons. Sperm Whale or Physeter macrocephalus is considered as the largest toothed whales and largest toothed predator. You can also check Blue whale vs sperm whale comparison.

Sperm Whale is the top living member of Physeter Genus, and they are in high extant species in sperm whale family. Blue Whale is a massive sized animal is also the loudest animals on the earth. Calls of the Blue Whales can be heard in several miles away as well as far below the surface of an ocean.

Facts About Blue Whale:

Blue Whales are referred as having deep blue color at the water surface, and it normally appears in the grayish blue. Despite being largest animal on our planet, Blue Whales are primary diet are krill, small aquatic life form resembling that of the tiny shrimp. Fully matured Blue Whale could grow at a length of 100 ft. Long and weighs more than 150 tons. These massive animals have their body relatively slim and streamlined to enhance the speed to a longer distance.

Blue Whale could swim more than 25 miles per hour or when they feel threatened. The Blue Whale normally has the small triangular dorsal fin when compared to a larger dorsal fin. Blue whales flippers would measure 12% of entire length of the animal.

Blue Whale are have bristle baleen plates that are attached to it and they act as the fence allowing the blue whale to capture prey. They also allow water to move freely in and out of its mouth. Primarily blue whale consume krill and many other small ocean creatures like copepods also be ingested. They maintain the steady diet with the high concentrations of krill in the Arctic Ocean.

Blue whales do not have teeth so they are unable to bite or chew the prey and they use the method called as the “Filter Feeding” to obtain their prey. Filter feeding of the groups of krill could be easily consumed to a large extent.

Facts About Sperm Whale:

The Sperm Whale or Physeter Macrocephalus are the large toothed whales from the cetacean species. Sperm Whale could easily grow to the length of 67 ft, and they also have the large brain in the whole animal kingdom. Spermaceti organ is located at the head of this whale hence the name Sperm Whale.

Sperm Whale grows to be around 50 to 55 ft in length and they weigh around 35 to 45 tons. The largest whales measure up to 67 ft and weigh up to 65 tons. Female sperm whales tend to be smaller growing compared to male. This type of whale normally has the unique body, and they could be easily confused with other species of whale.

Standard diet of Sperm Whale will be medium to large squid, fish, and octopus. The Sperm Whale has a deep diving behavior, and they have unique hunting methods and the way of consuming food.

Blue Whale Vs Sperm Whale Comparison:

With the larger in size, Blue Whale could move much faster in the ocean. Length and weight of the Blue Whale are not a problem for diving faster in the ocean. Sperm Whale is quite smaller when compared to the Blue Whale, and they could also swim faster.

Sperm Whale could easily hunt down for food below the surface of the water using the echolocation system for tracking the food as well as for the navigation in the ocean.
