Pharyngula: Evolution of the cichlid mandible

Sidney the cichlid's permanent pout
left all of his siblings in awe;
A chip off the block, beyond any doubt.
Young Sid had his father's strong jaw,
and his daddy's fine dorsal, pelvics and pecs,
plus a sizeable section of gill
before he lost interest. He'd paid his respects
and received his fair share of the will.
