Taratect

Taratect is a possible evolution for Small Taratects and Small Poison Taratects, being essencially the species' adult form.

Synopsis
Kumoko is given the option to evolve into a normal Taratect twice, when she reached the level-cap for Small Taratect and Small Poison Taratect. However, she opted against it on both occasions in favor of the rare Small Poison Taratect and small and agile Zoa Ele, as the size increase of the main species would be disadvantages in the narrow Great Elroe Labyrinth.

Later, after Kumoko initiated a mental attack on "Mother" to cancel the effects of her Kin-Control, the Queen Taratect send several of her offspring, including multiple normal Taratects, to eliminate her. However, they were all killed by the rogue Taratect.
