[X] Some Slina lost their mouths and instead developed specialized, teeth-like spikes. They use them to literally suck out organs from their prey bodies. Those spikes allow them to pierce Drekin shells and have added benefit of allowing the Slina to also consume, stored Boom Blamp energy, allowing this Slina subspecies to safely attack and consume Boom Blamps.
[X] Some Harpoon Slina develop a new hunting strategy by secreting a sedative from their external tissue layers. It lets them booby-trap hunting perches and webs alike, so that both Drekin, Slina are viable prey. 'Trapped' in a web, they strike when their prey succumbs to the laced webs.
[X] Some Splitter Slina begin to draw in prey through suctioned force. By drawing air through one head and expelling it out the other they form a type of cyclone. By splitting one head may direct air away from or towards another to better manipulate their environment
[X] Some Slina evolved leeching mouthparts on both of its heads and gained a mutualistic relationship with the Vent Blamps. These Slina will attach themselves between two Vent Blamps, tethering them to each other while draining a little of their energy. By doing so they provide these Vent Blamps with a way to reach each other for breeding purposes, and the Vent Blamps would place their buds on the Slina itself, only needing to return to the ruins to seek shelter from storms.
