Fast Facts: Bowhead Whale

-

 

Yeah, the Bowhead Whale needs some time to get used to looking at. Yeah, that curved line is actually its mouth. And yeah, its mouth does take up two-thirds of its head. 

The Bowhead Whale : Balaena mysticetus

Description: Bowhead whales have extremely large mouths and wide jaws that allow them to swallow an incredible amount of prey in one gulp. They actually have the largest mouth of nay animal! A distinctive white patch on their jaws stands out against their all-black bodies, and unlike many other whales, dolphins, and porpoises, Bowheads don't have a dorsal fin. However, they do have two small pectoral fins. Reaching lengths of up to 66 feet long, the Bowhead's skull and jaws make up about 30-40% of its entire body, which is covered in up to 20 inches of blubber, the thickest layer of blubber of any whale.  In addition, at full maturity, the Bowhead Whale weighs about 100 tons. 

Habitat: Although Bowheads do migrate to Canadian regions during the summer, they are one of the few marine creatures that live exclusively in the Arctic and Subarctic oceanic regions. Based on the annual climate, which affects the melting and formation of the Arctic ice, Bowhead migration patterns vary slightly each year. 

Diet: Bowheads are Baleen whales, which means they can take in huge amounts of sea water to strain through special baleen plates which allow the Bowheads to filter out invertebrates like plankton and crustaceans. Bowheads actually have the largest baleen plates of any animal and mainly feed on krill. In addition, they may also supplement their diet with small fish and other marine creatures. 

Behavior: Either traveling with small pods with about six members or by themselves, Bowheads aren't as sociable as other whale species such as the Beluga Whale. However, Bowheads are very vocal and communicate during migrating, feeding, and the mating season. During the mating and breeding season, Bowheads produce intricate and varied songs similar to those of a Humpback Whale. Also, similarly to Humpback Whales, Bowheads perform surface behaviors like breaching or simply drifting at the surface to rest. 

Conservation Status: The overall global population of Bowhead Whales is considered to be Least Concern; there are around 10,000-12,000 Bowheads left in the world. However, in some areas, such as Greenland, Bowheads are considered to be Endangered. 

Unique Traits:  The Bowhead's unique bow-shaped skulls allow it to completely break through the Arctic ice from underneath the water. These triangular skulls allow Bowheads to break up to 2 feet of solid ice! This is crucial as Bowheads come up for air around every 9-18 minutes, although Bowheads may dive for up to an hour before resurfacing.

Acadia National Park - Info & Imagery

-
Image
  New England feels...this is what the great 17th & 18th century poets and writers engraved in stone and ink saw in their worlds Acadia National Park. Nestled in the crook of Acadia, Maine, established in 1917, and known for its sweater vibes and autumnal beauty seemingly year round, this national park is known for its stunning scenery above all else. Wintery mountains, teeming forests, and pink granite shorelines are sights to behold on their own. But as the eastern-most National Park in the US, Acadia is also the first National Park to greet dawn every day. Imagine...the light spilling up over ocean salt breeze, pouring over the trees and rocks and sea. A striking world illuminated from the inside out.  Some of these places just don't seem real sometimes. But they are, and besides having great lighting for a Instagram photo shoot, the National Parks' beauty and meaning and history means something to us. These parks, surreal little worlds that offer more than escape,...

The National Parks!

  New Year, new explorations. I have to be honest; I haven't visited one of our 63 National Parks yet. Bing has this great catalogue of the National Parks and hotel/flight prices for each. Don't get too distracted by the beautiful photos of each park. It's too damn expensive for a college student to visit, well anywhere, right now.  So instead, I'm writing about the parks from my cozy-already-expensive enough dorm. The previous series on this blog have covered rainforests, oceans, and the ecosystems in between. Here, the National Parks are their own unique ecosystems, far more complex than being simply described as just a grassland or just  a desert. There's a reason why each park was designated as a government protected piece of land. Every park has history, distinct flora and fauna, and some beautiful crazy fun fact-esque aspect that makes these parks feel like other worlds.   Before we dive into some of the spotlights on the National Parks, I want t...
