Why do some animals lay more eggs than others?
Clutch size in birds and reptiles has long been studied by biologists, who have found generally that species that are short-lived or have a low survival rate among their offspring tend to lay more eggs at one time to increase the chances of having surviving offspring.
Why do some animals have so many babies?
The number of offspring a species produces is finely tuned to optimize its chances for survival. For some, the best strategy is to produce a great number of relatively small young; though predators will consume many of them, the odds are good that at least a few offspring will survive to maturity.
Why do some animals lay hundreds of eggs at a time?
Animals like frogs and fish lay hundreds of eggs and release millions of sperms. But the entire eggs do not get fertilized and develop into new individuals. ... Thus, production of large number of eggs and sperms is necessary to ensure fertilization of at least a few of them.
Which animal lay more eggs?
The mola, or ocean sunfish, looks like an animal cracker someone bit in half. At 5,000 pounds, though, this temperate and tropical water animal is the world's heaviest bony fish. It's also the heavyweight egg producer, releasing 300 million eggs over a spawning season.
Can a bird only lay one egg?
Photo by Aditya Sridhar via Birdshare. Different species of birds lay different numbers of eggs per clutch, but pretty much all birds lay at most one egg per day. ... Clutch sizes vary within and among species. For example, a Laysan Albatross lays only one egg per clutch; an Adelie Penguin typically lays two.
Can a human and a cat have babies?
Probably not. Ethical considerations preclude definitive research on the subject, but it's safe to say that human DNA has become so different from that of other animals that interbreeding would likely be impossible.
Why do humans usually have one baby?
As such, evolution dictated that survival is maximized for our species when there is only one baby at a time, as the overworked parents can give more required nurturing to one child at a time than five or six, and as such, that child is more likely to survive.
Why do humans not give birth to as many babies as frog do?
frogs reproduces more because there is one father but the number of mothers are more because there could be any number of females that can be fertilized whereas in humans internal fertilization takes place so the sperm can only fertilize one egg.
Why frogs and fishes lay so many eggs?
Compared to hens, fish and frogs lay hundreds of eggs because: - In Fish and Frogs, external fertilization occurs. ... Therefore, a large number of gametes in these species are produced to increase the chances of fertilization.
Why does frog lay so many eggs at a time?
Frog eggs are surrounded by “jelly.” What is its function? Amphibians generally lay large number of eggs. Often, many adults lay eggs in the same place at the same time. This helps to ensure that eggs will be fertilized and at least some of the embryos will survive.
Why do aquatic animals lay thousands of eggs?
fish lays thousands of eggs because some of them are eaten by big animals and some of them don't get enough Oxygen and some more things that they can't grow , So fish has to lay many Eggs so that so of them becomes a new one.
Does frog lay egg?
Most frogs and toads begin life as eggs floating in the water. A female may release up to 30,000 eggs at once. Each species of toad and frog lays eggs at different times. ... Frogs lay them in clusters, or large globs.
Why do some animals lay a few eggs?
Explanation: Some animals give eggs in large number because they know that there are many predators that would eat a lot of their eggs. So, to continue their species' race they lay eggs in large quantities.
Do snake lay eggs?
Answer: No! While snakes are known for laying eggs, not all of them do so! Some do not externally lay eggs, but instead produce young by eggs that are hatched internally (or inside) the body of the parent. Animals that are able to give this version of live birth are known as ovoviviparous.
How many eggs do snakes lay?
As a result, snakes typically lay anywhere from 3 to 100 eggs, though the exact number differs based on species. It's impossible to say how many eggs survive because a number of factors affect survivability.
Do peacocks lay eggs?
During the summer months peahens start laying eggs. A peahen will lay one or sometimes two clutches of eggs during the peafowl breeding season. Each clutch can have up to six eggs in it. ... If you want to incubate the eggs they should be taken away from the peahen.
Do penguins lay eggs?
All penguin species must return to land or ice for breeding. They will time breeding to an optimum time for productivity in the ocean for finding food to their chicks. Emperor and king penguins lay one egg while all other penguins lay two eggs. When laying two eggs, they are spaced between 24-48hrs apart.
