   • The jaw morphology of deep-sea dragonfish is adapted to capture large prey; being long with large fang like teeth. The function of the “loose jaw” was examined to look at its mechanical properties and it was found that forces that resist lower jaw adduction was greater in fish with shorter jaws. As such dragonfish were found to attain fast adduction velocities due to a drastic reduction in resistive forces. Additionally, adductor mass is decreased as not as much mass is needed to achieve such high velocity. This adaptation, the loosejaw, allows for dragonfish to be more competitive when hunting for prey. This all is very interesting as it makes sense for a deep sea organism to exhibit decreased muscle mass in order to reduce metabolic expenditures. This article will be good to start in terms of talking about the jaw of dragonfish and how it has evolved morphologically to survive in the deep sea.

   • Many deep sea dragonfish exhibit transparent teeth. This paper finds that the transparent teeth is due to a mixture of nanocrystalline and amorphous phases. It contributes to reduced light scattering leading to what is seen as transparent teeth. This allows them to thrive in the aphotic zone as they do not appear to have teeth/ be a threat. Their teeth is also really hard and stiff (more than piranhas and great white sharks. This article highlights the evolutionary adaptation of the dragonfish teeth in order to make them efficient predators who are able to thrive in regions of low food availability. Having knowledge of both jaw structure and teeth makeup is important to understand and infer the feeding behaviors of these fish and how they hunt for their prey in zones of the ocean that are very scarce in food.

   • This article looks at the structure of teeth of specific species of dragonfish. It looks at the specific materials that make up the teeth and includes imaging of the structure of the teeth. Looking at the teeth as the means through which dragonfish feed on their prey, the article highlights the length and rigidity of the teeth and the need to open its mouth very wide. This connects well with the Kenaley article that looks at the biomechanics of the jaw and how it is able to open it so wide. The article also talks about the attachment of teeth to the jaw which is interesting to examine in terms of jaw morphology. Understanding the attachment of teeth to the jaw can highlight the functionality of attachment. Different articles show slightly altered attachment of the teeth to the jaw which allows for questions to be brought up about the advantages and disadvantages that such attachment style will concur.

   • This article examines both the bone and teeth makeup of two species of stomiidae. It found that the species have long and sharp teeth as supported by other articles as well as elongated jaw bones. Also found the teeth to be partially hinged and incompletely fused to their bony support with unmineralized ligament that connects the tooth to the jaw. This article provides another source that looks at both the teeth and jaw of dragonfish and how it allows them to feed on large prey and survive. Focusing on a specific species of dragonfish provides additional insight into how stomiidae have evolved to have such interesting adaptations. The article gives specific examples of bone and teeth makeup which is important as it allows for the narrowing down of the topic of interest from broad to specific.

   • This article looks at the head joint of deep-sea dragonfish (stomiidae). Stomiidae have their pectoral girdle separated from the skull as well as a flexible connection between the occiput and the first vertebra (notochordal occipito-vertebral gap). The article discusses the functional relevance of such formations which contribute to the dragonfish’s ability to consume such large prey. This is an interesting article as it provides additional information on the way the jaw has adapted in order to allow stomiidae to survive in the deep sea. However, unlinke the other articles, this one focuses on the head joint and how that in conjunction with the long, partially unhinged jaw allow the dragonfish to prey on larger organisms and effectively hunt them to survive.
