Broadcast fertilization requires a great excess of egg and sperm gametes because most are wasted. Aquatic animals, such as starfish and sea urchin, mate in this manner.
They Have Internal Fertilization
As with most amphibians the fertilization is external. The female releases the eggs and the male fertilizes them. Amphibians, even toads, need water to reproduce.
external fertilization is external
Yes, bryophytes, like mosses and liverworts, require water for fertilization. This is because they rely on water to transport sperm from the male gametophyte to the female gametophyte for fertilization to occur.

External fertilization and development
External fertilization occurs when the union of egg and sperm takes place outside the bodies of the individuals involved. It is common in aquatic animals such as fish and amphibians, where both gametes are released into the water for fertilization to occur. This type of fertilization is less reliable than internal fertilization as it is subject to environmental factors such as water currents and predation.
