extinct genus of lobe-finned fish, Mandageria was
predators of other fish. With the exception of the pectoral fins that
are situated near the head, all of the other fins are located in more
posterior locations towards the tail. Because these fins were here,
they could help increase the surface area that pushed against the
water as the tail moved, making Mandageria (and
capable of sudden bursts of acceleration towards prey, closing the
distance between them before the prey could even react. The long
‘torpedo-shaped’ body of Mandageria is quite
common amongst fish
today, particularly fresh water genera that lurk amongst reeds while
waiting to ambush prey. Once prey was in the mouth, the sharp teeth
made certain that prey could not get away. The type species name M.
fairfaxi is in honour of James Fairfax.
At up to two meters long, Mandageria was fairly large for a lobe-finned fish, yet it was nothing near the size of Hyneria, another genus of lobe-finned fish which is considered to have been quite closely related to Mandageria.
