What else can I help you with?
Where do most animals that have external fertilization live?
They are aquatic.
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.
What fertilization is most common among terrestrial animals?
Yes, internal fertilization is a reproductive strategy used by virtually all terrestrial animals. In aquatic environments, external fertilization is much more common.
Differentiate between internal and external fertilization?
Internal fertilization occurs inside the female's body, where sperm fertilizes the egg, while external fertilization occurs outside the body, usually in water, where eggs are fertilized by sperm. Internal fertilization is common in land-dwelling animals, while external fertilization is common in aquatic animals. Additionally, internal fertilization provides better protection for the developing embryos compared to external fertilization.
How do animals fertilize plants?
Internal fertilization and external fertilization. Internal fertilisation means fertilize the egg inside the female's body. External fertilization is fertilize the egg after the female had lay it out. All mammals including platypus and spiny anteater do internal fertilization.
What type of fertilization and development occur in the zebrafish?
Zebrafish exhibit external fertilization, where the female releases eggs and the male fertilizes them outside of the body. The embryos develop externally, with the early stages of development taking place outside of the mother's body in the water.
Why do aquatic life use external fertilization?
Because sperm travels well in water.
The primary function of external gills in aquatic animals is to do what?
The primary function of external gills in aquatic animals is to exchanges gases. However, gas exchange is more difficult with external gills.
What are the 2 paterns of fertilization?
The two types of fertilization are 1. Internal fertilization 2. External fertilization Internal fertilization takes place within the body of the female. External fertilization takes place outside the body of female. It takes place by layong eggs.
External fertilization in animals?
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.
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
Why do you think there is a basic difference between the kinds of fertilization most common in aquatic and terrestrial animals?
the process of fertilization involves fusion of egg/ova and spermatozoa. the two cells are also called gametes. for their meeting aqueous medium is required. in land animals out side environment is dry therefore fertilization on land is not possible while as genital tract provides similar aqueous atmosphere where spermatozoon swim to reach the egg.
