Do sharks lay the largest eggs?

Only oviparous sharks lay eggs, as most bony fish do.

Neverthless, the list of oviparous sharks is vast. I will try no mention just a few species:

- Several species of bull sharks, like the horn shark (Heterodontus francisci).

- The crested bullhead shark (Heterodontus galeatus).

- The australian swellshark (Cephaloscyllium laticeps).

- The zebra shark (Stegostoma fasciatum).

- The swellshark (Cephaloscyllium ventriOSum).

- The striped catshark (Poroderma africanum).

(Most catshark species are oviparous.)

- The saddle carpetshark (Cirrhoscyllium japonicum).

(Also most carpetshark species are oviparous.)

However, the majority of sharks species are ovoviviparous.
