==Explanation==
The Space Shuttle was a reusable spacecraft system used by {{w|NASA}} from 1981 to 2011, after which it was decommissioned. In this comic, Randall suggests that the nature of the shuttle was in doubt or misunderstood until either an intact 'specimen' (of which there are four) had been dissected, or possibly the remains were reassembled from the two that were [https://www.youtube.com/watch?v=yibNEcn-4yQ lost in accidents]. 

With its shape, shown in the small image, and the tail fin, it looks a bit like a {{w|Osteichthyes|bony fish}} or {{w|Batoidea|ray}}. The joke is that after the shuttle was taken out of use, its skeleton was analyzed, and as shown in the comic, was found to have a skeleton typical of a mammal, with details such as the pentadactyl quadripedal bodyform hidden beneath its aerodynamic sweep, as well as having bones (i.e., not primarily cartilage). This morphology is similar to that possessed by a whale. However, it should be noted that the skeleton has several features not found in mammals, e.g. the ribcages extending all the way to the pelvis and past the shoulder these features are more reminiscent of snakes. Of course, the skeleton of a spacecraft is not made of bones, but rather of [https://www.nytimes.com/2003/04/22/science/inquiry-focuses-on-skeletons-of-space-shuttles.html metal] and other manufactured materials.{{Citation Needed}}

As the understanding of the natural world developed, many taxonomic misconceptions were overturned, or at least the scientific terminology was tightened. For instance, it was found that dolphins and whales were mammals, not fish.<sup>&#91;''{{what if|156|cetacean needed}}''&#93;</sup> Because of convergent evolution – the tendency for distantly-related species to adapt similarly to a given environment – it is often not easy to properly classify organisms merely by observing their exterior. For example, whales and fish have very similar body shapes, as did the extinct plesiosaurs, because life as a swimming vertebrate favors the same adaptations. In lieu of genetic analysis, or even of sufficient observation of them in the wild, the main progress in understanding differences among marine animals was often in dissecting the corpses of creatures found stranded or caught in nets, or reconstructing them from skeletal remains. Together with fossil evidence, insights were developed about their origins and differences from others' origins.

The title text conflates the now-extinct {{w|Steller's sea cow}}, an aquatic mammal related to manatees and named after explorer/zoologist Georg Steller [https://www.britannica.com/biography/Georg-W-Steller (also extinct)], with the adjective "stellar", which means being of a star or stars, such as inter-stellar space or stellar masses. While this conflation is often done accidentally, due to the name Steller being much rarer than the adjective "stellar," in this case it is probably an intentional pun.

One might expect that the idea for this comic may have come from the recent California Appeals Court ruling that [https://www.wsj.com/articles/when-is-a-bumblebee-a-fish-when-a-california-court-says-so-11654611927?st=umo4uckleempt0e&reflink=desktopwebshare_permalink bumblebees are considered fish] under a law which categorized several other invertebrates as part of a broad colloquial category of fish (as in "Fish and Game Department" designations.) However, given the short time between the ruling and the comic's release, it is likely that this was a coincidence.

The comic also prominently conflates biology with artifice, a budding and controversial concept in these times of rapid AI use and research.

==Transcript==
:[In the upper right part of the panel there is a small drawing of the Space Shuttle as seen from above. Beneath it, and to it's left, is a much larger drawing with the same outline as the Shuttle. But this time the outer layers have been removed to reveal the inside. This has revealed a skeleton taking up the entire space inside. The head is in the front, and legs and tail at the rear, with arms and fingers in the wings. Probably looking somewhat like a bats "hand/wings". The bones are white with the frame of the shuttle gray or black. Some of the lines outlining the design of the shuttle is both on the small and the large drawing, along the wings and rear engines. Both feet and arms have five fingers/toes.There seems to be 24 ribs in the very long rib-cage.] 

:[Caption beneath the panel:]
:The Space Shuttle was long assumed to be a type of fish or shark, but after it was decommissioned in 2011, analysis of its skeleton determined that it was actually a mammal.
