This is a couple months old, something I sketched up for Hearsay, another alien on Otah's planet.
Hearsay, or Quarrelers, are the Apex hunters.
They are the biggest and the baddest.
Otah is barely a dent in their whole reign of terror.

Hearsay is one of the oldest and most violent of his kind.
He is sought out as quarry for many sapient aliens who come down and hunt on the oceanic planet.

There are small claspers apparent on these giant beasts, but they have since evolved beyond that, simply because they are so solitary they often attack and kill each other.
They instead swim past each other, dropping their own respectable substances (eggs for female, sperm for males) and then scrambling to get away before the other gets tired of their shit.

Hearsay is mine
