The 17 pages that link to Internal fertilization, each with the reason it gives.

• AmnioteRelated: It allows amniote reproduction to avoid the external fertilization common in many amphibians.

• AmplexusCompared with: Amplexus typically accompanies external fertilization, while some amphibians fertilize internally.

• ChondrichthyesRelated: Male chondrichthyans use claspers to transfer sperm during mating.

• External fertilizationCompared with: It contrasts with external fertilization in the location of gamete union and the conditions surrounding it.

• OvoviviparityBroader topic: Internal fertilization commonly precedes the retention of eggs in ovoviviparous animals.

• Reproductive systemCompared with: It depends on reproductive anatomy that transfers or receives gametes internally.

• ReptiliaRelated: It allows reproduction without releasing gametes into water.

• Parental care in fishCompared with: Live-bearing fish can protect embryos internally rather than guard external eggs.

• GuppyRelated: Male guppies transfer sperm with a modified anal fin called a gonopodium.

• OphidiiformesRelated: Internal fertilization occurs in some ophidiiform lineages, including certain brotulas.

• CopulationRelated: Copulation often enables sperm to reach eggs within the reproductive tract.

• HalfbeakRelated: Internal fertilization occurs in several halfbeak lineages and accompanies live-bearing in some.

• CyprinodontiformesRelated: It occurs in the livebearing lineages of Cyprinodontiformes.

• MatingRelated: Many mating systems transfer sperm into a partner before fertilization.

• Fish pregnancyRelated: Internal fertilization commonly precedes fish gestation, but does not by itself mean embryos are retained.

• SebastinaeRelated: In Sebastes, fertilization occurs internally before developing young are released.

• Tailed frogRelated: The male’s tail-like organ transfers sperm internally, unlike the external fertilization typical of frogs.
