This was the first published paper on the Narluga skull by the marine biologist who found it and one of his colleagues. This paper concludes from morphological and anatomical metrics that the skull is either an anomalous beluga, an anomalous narwhal, or a hybrid of the two. I will use this paper to support information already in the Wikipedia page and elaborate on it. I will also include information on the description of the hybrid as given by the hunter that the marine biologist spoke to.

Hybridization between two high Arctic cetaceans confirmed by genomic analysis. Scientific Reports, 9(1), Article 1. https://doi.org/10.1038/s41598-019-44038-0

This paper was the first to confirm the hybrid status of the narluga skull through genetic analysis. Additionally, it identified a novel foraging niche through stable isotope analysis. This paper is already cited in the Wikipedia page for the genetics work, but I would like to add information on the stable isotope analysis and the predictions of the author. Specifically, the fact that they state that the increased levels of isotopic carbon indicate a benthic foraging strategy.

This paper examined the mating systems of belugas and narwhals. They found that the narwhal's tusk is likely kinked to female mate choice, and that belugas are likely more promiscuous, while narwhals are likely more polygamous. I intend to use this information to contextualize the potential for hybridization for these two species in a new section on the page titled something like "Species Compatibility." In this section. I will include different metrics of narwhal and beluga physiology and behavior to explain the compatibility, or lack thereof, between the two species.

This is a very detailed manuscript covering mating and feeding ecologies of belugas and narwhals. It covers such topics as sexual size dimorphism and stable isotope analyses. I have not had the time to do a deep dive into this paper, as it is over 200 pages long, but I plan to use the information on each species to strengthen the Species Compatibility section of my contribution. This paper also briefly mentions that hybridization could result in a loss of local adaptation

This paper dives into the effects of climate change on cetaceans as a whole, with sections for each region of cetacean occupancy. The authors found that rising sea temperatures and reduction in sea ice are driving many cetacean species poleward. I will focus on the section on Arctic cetaceans, which states that belugas and narwhals are among the most threatened by climate change in this region. This paper also states that their ranges are likely contracting due to climate change, which will strengthen my Species Compatibility section, as they are more likely to interact with one another.
