Bloodhound, for pack creatures how about these?

Jointed Killers, AKA the compounds (bc of their eyes)

Bug creatures with 10 legs and a scorpions tail with a mantis body at the front

Creatures so intelligent they can solve mathematical equations, they travel in packs, using camouflage to hide on the ceiling or other such surfaces, they have a frog like tongue that they use to wrap around the necks of their prey and suffocate them. They also use the tails mainly as whips with the poison on the tip
