What animal produces the most offspring?

Baby, Baby

Insects are no slouches when it comes to reproduction and the African driver ant, which can produce 3 to 4 million eggs every 25 days, is thought to be the most generous of all.

Why do some animals have large amounts of offspring and others have low amounts of offspring?

The presence or absence of predators is an important factor influencing the size of offspring and litters. In general, when comparing closely related snakes, the one with fewer natural predators often produces litters of fewer, larger young than those from predator-rich environments.

What are R and K-selected species?

r-selected babies grow rapidly, and tend to be found in less competitive, low quality environments. ... K-selected species produce offspring that each have a higher probability of survival to maturity.

Which offspring species is most likely to survive?

Offspring with favorable variations are more likely to survive and reproduce. Gradually, individuals with favorable variations make up more of the population.

What animal has 32 brains?

Leech has 32 brains. A leech's internal structure is segregated into 32 separate segments, and each of these segments has its own brain. Leech is an annelid.

What animals can have more than one baby at a time?

Sheep and goats produce 1 to 3 offspring per gestation on average and can produce two litters per year. Both species sometimes give birth to quadruplets and on rare occasions even more. Pygmy and Nigerian dwarf goats are especially likely to produce more than 3 kids per gestation.

Why some animals reproduce large number?

In fact, all animals produce more offspring than can survive long enough to reproduce themselves. ... The number of offspring produced is often related to the amount of parental care. Typically, the higher fecundity, the lower the amount of time parents devote to caring for the offspring.

What is AK strategist species?

K-selected species, also called K-strategist, species whose populations fluctuate at or near the carrying capacity (K) of the environment in which they reside. ... K-selected species are characterized by long gestation periods lasting several months, slow maturation (and thus extended parental care), and long life spans.

Which curve's would you expect to represent species that have few offspring but care for them well?

Type I or convex curves are characterized by high age-specific survival probability in early and middle life, followed by a rapid decline in survival in later life. They are typical of species that produce few offspring but care for them well, including humans and many other large mammals.

Are sea turtles R or K-selected?

r/K selection as a continuous spectrum

Similarly, reptiles such as sea turtles display both r- and K-traits: although large organisms with long lifespans (should they reach adulthood), they produce large numbers of unnurtured offspring.

Are humans R or K?

Elephants, humans, and bison are all k-selected species. On the other hand, r-selected species often inhabit unstable environments and are completely density independent. These species often have short life expectancies, produce as many offspring as they can, and invest very low amounts of parental care.

Are Lions R or K-selected?

Common examples of k-strategists species include humans, lions and whales.

Which organism are most likely to survive?

According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.

What are R species?

r-selected species are those that emphasize high growth rates, typically exploit less-crowded ecological niches, and produce many offspring, each of which has a relatively low probability of surviving to adulthood (i.e., high r, low K). A typical r species is the dandelion (genus Taraxacum).

When more offspring are produced than can survive?

Competition: More offspring are produced than can survive, so offspring with traits better matched to the environment will survive and reproduce more effectively than others. 4. Natural selection states that given these three conditions, a population will accumulate the traits that enable more successful competition.
