Frog Development
- Frogs are anuran amphibians with separate sexes.
- Males have testes and females have ovaries.
- During breeding season, males copulate with females in a process called amplexus.

- Fertilization is external.
- Development is indirect, with a larval stage called a tadpole.
- Frogs exhibit sexual dimorphism, with males being smaller and having vocal sacs and nuptial pads.

- Sperm is haploid.
- Microscopically small, approximately 0.03 mm in length.

- The head contains the nucleus.
- The mid-piece contains mitochondria.
- The tail facilitates movement.
