Cnidolium moderitannus split from its ancestor, cnidolium simplistica, and moved into warmer territories. This was thanks to a strengthening of their resistances to heat, granting them new areas to feed away from their relatives, thereby succeeding in not putting any of their brethren at risk of extinction.
Both flagella have increased in strength to aid in swimming against the currents within the coastal waters many call home, and to keep up with this increase in speed, their oar-like cilia have increased in size and strength as well, thereby matching their control along with their speed.
They eat the same way as their ancestors did, only now they are better at it, as their tentacles have increased in length, their horn has shrunk somewhat to provide the tentacles a better ability to pierce the membranes of foes. As for their eyes, both the tentacle eyespots and the sensitive nucleus are more sensitive, aiding in their becoming better hunters.
In terms of defense, their cnidocytes cover more sections of their body, as they can regenerate them faster now. This is done by moderitannus taking up a secondary hemophagous diet, wherein they feed on small species, typically the young of creatures such as the green swarmer, which are small enough that they can puncture to the blood/sapstream. With this excess of incoming energy, they are able to risk using their cnidocytes as offensive tools to catch prey now, although they only function for specific prey species, whose specific touch triggers the mechanisms in contact with the organism to fire, impaling it. This is often deadly to the target, and they are still absorbed into the body through the acidic membrane.
Despite their newfound love of the tropics, many can still be found mixed with their brethren in the temperate waters they have long been so accustomed to.
