Article Evaluation

 * I decided to evaluate the wiki page for the walrus
 * the article was on topic, nothing distracted me from the main focus
 * there article was neutral, and didn't make any bias claims
 * there were many different references
 * the citations I clicked on worked and supported the claims on the wiki page
 * there weren't too many conversations going on in the talk page
 * the article is related to to our course because we have talked about the walrus in class since it is a marine mammal
 * the article was very similar in terms of biology about the walrus, but the "interaction with humans" section had things that we don't really cover in class

Article Draft

 * my group initially believed that we would have to make a new page for our species, Baird's beaked whale
 * we later found out that there was a giant beaked whale page that mentioned the Baird's beaked whale, and another species called Arnoux's beaked whale.
 * we instead decided that we would edit this page
 * there was already a physical description section, which was the information that I was tasked with adding
 * This section included physical descriptions of two beaked whales, so I'll look up information about Baird's and Arnoux's beaked whales
 * I noticed that I could expand a bit on the information about the sizes of the whales and the lack of sexual dimorphism
 * I could also add information of the shape of their blows, jaw, and color pattern.
 * the biggest problem that I found was that this section did not really cite its sources too well, so I might end up rewriting most of it

'''The two established species have very similar features and would be indistinguishable at sea if they did not exist in disjoint locations. Arnoux's is generally smaller. Estimated lengths of live Arnoux's at sea have been up to 12 m, but all dead specimens have been considerably smaller of around 9.3 m to 9.75 m. The Baird's, on the other hand, have been confirmed to grow to 12 –. The weight is up to 14,000 kg.'''

'''Both whales have a very long prominent beak, even by beaked whale standards. The lower jaw is longer than the upper and the front teeth are visible even when the mouth is fully closed. The melon is particularly bulbous. The body shape is slender—the girth is only 50% of length. The body is uniformly coloured and a particular individual's colour may be anything from light grey through to black. The flippers are small, rounded and set towards the front of the body. The dorsal fin similarly is small and rounded and set about three-quarters of the way along the back. Adult males and females of both species pick up numerous white linear scars all over the body as they age and may be a rough indicator of age. There is little sexual dimorphism in either species.'''

A third and as yet unnamed species (informally known as "Karasu" (Japanese for raven)) was described in 2016, based on differences in mtDNA haplotypes between black and gray forms of Baird's beaked whale in the North Pacific. For the time being, the following text treats Baird's beaked whale as monospecific.


 * I will keep the whale.org source for arnoux's, and compliment it with a page on baird's from the same site
 * The measurment of the arnoux matched the source, but the the source did not mention distinctions between living and dead species
 * edited section is as follows

The two established species have very similar features and would be indistinguishable at sea if they did not exist in disjoint locations. Both whales reach similar sizes, have bulbous melons, and long prominent beaks. Their lower jaw is longer than the upper, and the front teeth are visible even when the mouth is fully closed. This can result in having their front facing teeth being covered in barnacles after many years. Baird's and Arnoux's also have similarly shaped small flippers with rounded tips, and small dorsal fins that sit far back on their body. Adult males and females of both species pick up numerous white linear scars all over the body as they age, and may be a rough indicator of age. These traits are similar in both sexes as there is little sexual dimorphism in either species.

Although fairly similar, there exist some differences between both species. Baird's beaked whales are around 4.6 meters when born, and can reach lengths of 11.1 meters as adults, making them the largest members of the beaked whale family. Baird's have fairly narrow body shapes despite their large size, and have dorsal fins that are rounded at the tips. Their coloration is fairly uniform and can range from grown to grey. Arnoux's beaked whales are around 4 meters as calfs, and can reach lengths up to 9.75 meters as adults. Their bodies are not as narrow as the Baird's, and resemble a spindle. Unlike the Baird's beaked whale, Arnoux's have slightly hooked dorsal fins. Arnoux's have a dark coloration that ranges from brown to orange due to a build up of algae on its body.

A third and as yet unnamed species (informally known as "Karasu" (Japanese for raven)) was described in 2016, based on differences in mtDNA haplotypes between black and gray forms of Baird's beaked whale in the North Pacific. For the time being, the following text treats Baird's beaked whale as monospecific.

Peer Review
I did my peer review on the Bearded Seal, and I responded to a comment on the article's talk page with what I thought about the article.
