Devonian fossil fish
Where was it found?
Freshwater streams and estuaries
Diet and foraging method
Cephalaspis was presumed to be a bottom feeder because its mouth was situated beneath its head, which was lined with sensory patches to sense for its burrowing prey. It was heavily armoured with a head shield, thought to be a predator defence.
Social organisation and mating system
Did you know that...?
Cephalaspis were jawless and unable to bite, so they had to suck up prey with detritus from the river or estuary bottom.
