Spring has sprung, no not the season the suspension spring in my car; still it’s fixed and ready for another job interview later this week. Last week we saw the super speed antics of the Green Tiger Beetle and while few animals would be able to keep up with it this week’s creature, chosen by @ironspiderchan45, defiantly can’t. Hope you enjoy this gelatinous issue.

Issue #53 - Blob Fish
Kingdom – Animalia
Phylum – Chordata
Class – Actinopterygii
Order – Scorpaeniformes
Family – Psychrolutidae
Genus – Psychrolutes
Species – marcidus
Related Species - The Blobfish is one of the eleven species in the genus Psychrolutes* (1)
*The Blobfish, despite having a large amount of media attention is poorly known to science, with no living individuals seen in the wild. As such some of this information is based on its sister species, the Blob Sculpin (Psychrolutes phrictus)
Range - Blobfish are found at depths between 600 and 1200m off the coast of Tasmania and New Zealand.
Under Pressure
Blobfish are tadpole shaped fish that grow to just under a foot in length, and are a member of the fatheaded sculpin family. All members of this family, when brought to the surface morph their shape, becoming gelatinous lumps of flesh with little resemblance to their natural state. The reason for this change in morphology is down to the crushing water pressure the Blobfish and its relatives encounter in their usual home, one that crushes bone in a matter of minutes. As such the fish’s skeletal skeleton is soft and fairly useless at supporting the flesh, using water density in its soft tissue to maintain its shape instead (2).
Since its muscle structure is mostly water, the Blobfish is an inactive creature, often floating above the seabed snapping up anything that drifts past that fits in its mouth. Considering the lack of a reliable food source at such depths we can assume the Blobfish isn't fussy in what it eats, and that larger deep sea fauna that prey on it in turn for the same reason. While the exact predators of this species are unknown, Blobfish, and other deep sea sculpins in general, are often found with parasitic copepods attached to the skin.
While the reproductive traits of the Blobfish are unknown it can be assumes that they are similar to those of the Blob Sculpin, which differs only in geographic distribution, which lays its eggs on the sea floor and guards them until they hatch (3). The larvae of the Sculpin are narrow tadpole shaped fish which eventually mature into the more bulbous adults.
Five Fun Blob Fish Facts
The Blobfish gained media attention when the Ugly Animal Society voted it as their mascot in 2013
All known specimens of the Blobfish are individuals caught as bycatch; no one has ever seen a Blobfish in its natural habitat.
Because of this bycatch the Blobfish is labelled as an endangered species although no real estimates of their potential population size have been completed as of yet.
A Blobfish appeared in the Chinese Restaurant scene in Men in Black III as a tongue in cheek joke to the species alien appearance
Blobfish flesh is inedible to humans.

With a heart felt ‘Well that’s sad’ and a look of complete disgust the Blobfish is thrown back into the ocean depths. Next week we have an animal ready to help us shepherd in the Year of the Goat followed by a request from @cgoodness. Until then critic, comment and drop requests as well as checking out past issues in Impurest’s Bestiary.
Many Thanks
