How do snails fertilize internal or external?
Snails can either fertilize internally or externally, depending on the species. Most terrestrial snails, such as garden snails, engage in internal fertilization, where the male transfers sperm to the female's reproductive tract during mating. In contrast, some aquatic snails may practice external fertilization, releasing eggs and sperm into the water simultaneously for fertilization to occur. This variation in fertilization methods is influenced by their respective environments and reproductive strategies.
Is there external fertilization with live birth in fish?
In some species there is external fertilization. In other species there is live birth. Live birth requires internal fertilization.
What are the some disadvantages of external fertilization?
It depends. Are you talking about humans? 8D Humans use internal fertilization but the disadvantages in external fertilization is that a small number of eggs survive.

List of animals that have external fertilisation?
Some animals that have external fertilization include fish, frogs, sea urchins, and certain aquatic invertebrates like jellyfish and corals.
Is osteichthyes a internal or external fertilization?
An ostrich lays eggs after the mating ritual. Therefore, the fertilization process is internal.
A fish has what type of fertilization?
External!External fertilization takes place in fishes. This means that the sperm cell of a male is linked together with the egg cell of a female in the external bodies of the individual fish.
Did beetle is internal or external fertilization?
Beetles typically exhibit internal fertilization. During mating, the male transfers sperm to the female's reproductive tract, where fertilization occurs inside her body. This method allows for greater protection of the developing embryos compared to external fertilization, which is common in some other species.
Animals that undergo external fertilization?
Animals that undergo external fertilization include many fish, amphibians, and aquatic invertebrates. Species like salmon, frogs, and sea urchins release eggs and sperm into the water, where fertilization occurs outside the body. This method often requires moist environments to prevent gametes from drying out and to increase fertilization success. visit our website: www. sathayatravels .com/about
A type of fertilisation fish use in water?
Most fish use external fertilization. But not all, guppies and other livebearers use internal fertilization. Of the external fertilizers, some are broadcast spawners, whereas others are not.
Is fish development internal or external?
Fish development can be both internal and external depending on the species. Some fish, like most bony fish, have external fertilization where eggs are fertilized outside the female's body. Others, like some species of sharks, exhibit internal fertilization where fertilization occurs inside the female's body.
What kind of method of fertillization does the Agnatha do?
Agnatha, which includes jawless fish like lampreys and hagfish, typically use external fertilization. In this process, females release eggs into the water, and males then release sperm to fertilize them externally. This method often occurs in freshwater or marine environments, where the eggs and sperm are released simultaneously to increase the chances of successful fertilization. Some species may exhibit varying behaviors related to spawning, but external fertilization is the general method used by this class.
