Mouquet adds, “Our study provides, for the first time, the aesthetic value of 2,417 reef fish species. Mandarinfish are popular choices for saltwater aquariums. The ecological and evolutionary distinctiveness of unattractive fishes makes them important for the functioning of the whole reef, and their loss could have a disproportionate impact on these high-biodiversity ecosystems. Our innate preferences for shape and color are probably a consequence of the way the human brain processes colors and patterns, the authors say, but mismatches between aesthetic value, ecological function, and extinction vulnerability may mean that the species most in need of public support are the least likely to receive it. Furthermore, species listed on the IUCN Red List as “Threatened” or whose conservation status has not yet been evaluated had lower aesthetic value on average than species categorized as “Least Concern.” Unattractive species were also of greater commercial interest, whereas aesthetic value was not correlated with a species’ importance for subsistence fisheries. However, the species that were ranked as more attractive tended to be less distinctive in terms of their ecological traits and evolutionary history. Stuart Smith ( CC-BY 4.0)Ĭombining the public’s ratings with the neural network’s predictions, they found that bright, colorful fish species with rounder bodies tended to be rated as the most beautiful. They invest in durable relationships and – they are only as strange looking as we terrestrial bipeds would appear to them.Īnd if all of that is not enough for you, see the photo below for the indisputable reasoning for by Wolf-Eels are NOT ugly fish!Įnter your email address to follow this blog and receive notifications of new posts by email.The mandarinfish (Synchiropus splendidus) is among the reef fish species with the highest aesthetic values. It is a homebody that likes crunchy snacks and prefers that they come right by the front door they are great parents and are docile unless fighting for home or partner. The Wolf-Eel is indeed akin to us in so many ways. The males do compete for females who will sometimes opt to swap dens and go live with the competitor. Sound like any other species you know? Wonder if it happens at mid-life? It was long thought that Wolf-Eels always mate for life but, this is not always the case. One juvenile is even known to have travelled a minimum of 1,000 km having been tagged in Port Hardy, BC and found back in Willapa Bay, Washington two years later. The juveniles settle into the adult sedentary lifestyle between the ages of 6 months and 2 years (presumably dependent on food supply and den availability). Having a long tail also allows them to den-up, curling up and around in narrow spaces between rocks and. The long tail serves in locomotion, powering them forward with big, slow, s-shaped waves while being stabilized with the long dorsal and pectoral fins (see video below). ![]() They are the only member of their family that have this body shape. This is likely another driver for the male’s having such fleshy heads – they are better able to survive the wounds inflicted by such battles.Ĭlearly, another unique feature about this species is their eel-like body. They do also sometimes need to do battle for den space with a Giant Pacific Octopus. As adults, the females are smaller and a darker brownish grey (both remarkably camouflaged for when they are in their rocky dens). Both male and female juveniles are brownish orange and look even more eel-like, lacking the big head of the adults. In aquariums, their life expectancy is known to be at least 28 years. Wolf-Eels have long-lasting pair bonds, coming together when they are around 4-years-old and having their first clutch when they are around 7. ![]() The males do compete for females who will sometimes opt to swap dens and go live with the competitor.
