The Asterblob is to the Sticky Tangleblob as the Soopierworms are to the late Soopywoorm - a more derived, cohesive split of an unspecialized marine multicellular fauna. Unlike with what occurred in the soopyverme line, the Asterblob is different enough from its immediate ancestry to not completely replace it. The most significant alterations between the Asterblob and the Sticky Tangleblob have occurred internally. With a nerve net no longer adequate to coordinate a more elaborate organism, a ring-like ganglion has developed - more efficient at processing information and prompting the rest of the body to act upon it; dense branches of this ganglion are found within the Asterblob’s arms, giving them decent motor control - and thus the organism moves by the direction of one or a few “leading” arms. Said arms are also robustly muscled, and attach to bands of chitin for reinforcement. Developing independently from the Soopierworms, this organism possesses a hemocoel for distributing gases and nutrients throughout its body.

The Asterblob’s epidermis is covered with many fine vibration-sensitive setae, allowing it to react accordingly to the intensity of subaquatic motions. Under the tips of its six arms each lie a patch of photoreceptive cells, capable of detecting differences in light and some vague shapes. Lining the under margins of its arms are arrays of keen chemoreceptive setae, able to make out the distinct chemical signatures of its menu options. Speaking of the Asterblob’s diet, this fauna can graze down any living matter it creeps over that’s either too small or poorly-defended. Once prey has been captured, mobile denticles tear up and carry the foodstuffs towards its central orifice; and once it has its fill, specialized muscles rimming the orifice close up tight like a sphincter, which by then this meal is bathed in potent digestive compounds within a central digestive complex. An asymmetric anal pore expels any waste from feedings. As much of its more motile options carry a resistance to spite, the Asterblob employs “conventional” venom derived from its digestive compounds; venom administered via stinger-like setae and prey constricted by powerful arms means that whatever confronts it will very likely be made an easy meal. Certain denticles also aid in locomotion.

An Asterblob’s flesh contains trace quantities of spite, dissuading predators from nabbing an easy meal. To ensure continued genetic diversity and greater mutation rates among descendants, Asterblobs are capable of sexual reproduction. Expelling gametes into the water via a pore located between two of its arms, these conjugate and form innumerable Sooperpoopycell-like larvae. Similar to the Soopierworms, the distinctive tissues of the Asterblob are composed from three different cell lines. Bruh-line cells give rise to digestive and photoreceptive tissues, as well as the locomotory denticles. Most muscular, nutrient-store, and connective tissue - including that of the central oral sphincter and those attaching to the locomotory denticles - derives from asshole-line cells. Dermal tissues and sensory setae have their origins traced to poopy-line cells.

Although retaining the spite immunity common to all soopyfauna, Water Spite Flora are rather poor in nutrients, and thus do not compose a frequent portion of an Asterblob's diet.
