What's the difference between appendage and lungfish?
Appendage
Definition:

(n.) A subordinate or subsidiary part or organ; an external organ or limb, esp. of the articulates.

(20) Surgical techniques used (alone or in combination) included an isolation procedure in 1 patient, cryoablation in 4 patients, and excision of atrial appendages or portions of atrial free walls in 7.
Lungfish
Definition:
(n.) Any fish belonging to the Dipnoi; -- so called because they have both lungs and gills.
Example Sentences:
(1) Two of the corresponding lungfish trypsins were found to have identical amino-terminal sequences for at least 27 residues.
(2) Modern lungfish are air-breathing nonmarine forms, yet their Devonian forebears were marine fish that did not breathe air.
(3) The feeding mechanism of the South American lungfish, Lepidosiren paradoxa retains many primitive teleostome characteristics.
(4) The development of the vasculature of the pectoral fin in the Australian lungfish, Neoceratodus forsteri, was studied by the dye-injection method.
(5) Effects of adrenergic and cholinergic drugs were studied on isolated preparations from the heart, the lung and the spleen of the African lungfish.
(6) The overall pattern of the primary retinofugal projections is markedly similar to that of amphibians which suggests that lungfishes may be more closely related to amphibians than to actinopterygian fishes.
(7) Because there is such similarity between these results and effect of lung inflation on control of inspiratory time in mammals, it is postulated that neural circuits for control of respiratory timing were already developed and similar in the lungfish.
(8) Besides supporting the theory that land vertebrates arose from an offshoot of the lineage leading to lungfishes, the molecular tree facilitates an evolutionary interpretation of the morphological differences among the living forms.
(9) These results provide the first evidence for the presence of alpha-MSH-related peptides in the brain of a lungfish.
(10) Comarisons have been made of the structure of layers lining the lungs of lungfish, frog and rat using material fixed by perfusion of the pulmonary circulation of physiological pressures and at normal air pressures within the lung.
(11) Blood respiratory properties have been studied in awake and estivating African lungfish, Protopterus amphibius.
(12) Ascending PVO projections appear to be particularly well developed in lungfish compared with other species and may be related to specialized endocrine mechanisms in this group of vertebrates.
(13) Among living fish, the coelacanth Latimeria chalumnae (Actinistia), which is the only recent representative of the Crossopterygii (Actinistia and Rhipidistia), the lungfish (Dipnoi) and ray-finned fish (Actinopterygii), have each been considered as sister-groups of the tetrapods.
