| Question | Answer |
|---|---|
| chondrichthyes | oviparous is ancestral, can be oviparous, viviparous,, or ovoviviparous. can be lecithotrophic or matrotrophic, internal fertilization |
| actinopterygii | external or internal;, most oviparous although viviparity evolved multiple times, parental care ranges, anywhere on continuum of lecithrotrophic to matrotrophic |
| lissamphibia | oviparous or viviparous, man have internal or external fertilization, can be matrotrophic of lecithpotrophic |
| testudines | internal fertilization via penis, oviparous, lecithotrophic , temp dependent sex |
| crocodilia | internal fertilization via penis, oviparous, lecithotrophic, temp dependent sex |
| aves | gonads enlarge then atrophy, oviparous, internal fertilization via cloacal kiss or penus, lecithrotrophic |
| Anura | external fertilization, can have internal via cloacal kiss or intermittent organ. |
| urodele | hedonic glands, can be lecithotrophic and matrotrophic, most oviparous, internal fertilization |
| squamata | hemipenes, most oviparous, vivparity has evolved, lecithotrophic or matrotrophic, temp dependent sex |
| buccal pharyngeal pump | Chondrichthyes and actinopterygii |
| ram ventilation | obligate ram: makrel, tuna facultative ram: Chondrichthyes and actinopterygii |
| cutaneous respiration | testudines, amphibiuans |
| dual pump | anything using buccapharyngeal, |
| buccal pump | lung fish, amphibians, bidirectional, testudines |
| aspiration pump | amniotes (birds, mammals, reptiles) squamata, turtles (but there's it different) |
