What animals have complex life cycles?
Although butterflies and perhaps frogs might be the best-known examples of animals with complex life cycles, larval development is the mode of development most commonly found in the animal kingdom, with a wide range of representatives living in the world’s oceans (Young 2002).
What is a complex life cycle?
INTRODUCTION. I here apply the term complex life cycle (CLC) to a life history that includes. an abrupt ontogenetic change in an individual’s morphology, physiology, and behavior, usually associated with a change in habitat.
Why are some organisms considered to have a complex life cycle?
Some organisms are considered to have complex life cycles, not because of morphological changes, but because of changes in habitat. For example, many birds migrate long distances between their summer breeding grounds and their more southern wintering grounds.
What is the most complex life cycle?
Dicrocoelium dendriticum, commonly called the Lancet liver fluke, is a parasitic fluke that displays one of the most complex parasitic life cycles currently known.
Which life cycle is the simplest?
haploid life cycle
The haploid life cycle is the simplest life cycle. It is found in many single-celled eukaryotic organisms. Organisms with a haploid life cycle spend the majority of their lives as haploid gametes. When the haploid gametes fuse, they form a diploid zygote.
What is the life cycle of a shark?
A female white shark gives birth to just five or so “pups” every other year. Their slow reproduction process makes white sharks vulnerable to extinction. Scientists classify white sharks into five different life stages: Pups, Young of the Year, Juveniles, Subadults and Adults.
What kind of life cycle does an animal have?
Most animals including fish, mammals, reptiles and birds have very simple life cycles: they are born (either alive from their mother or hatched from eggs)
Which is the weirdest life cycle in the world?
Here are ten of the strangest ways animals enter the world. Adactylidium mites have such a rapid life cycle that they emerge from their mother already pregnant. These mites survive by eating the egg of a thrips—a winged insect that is less than 1 milimeter long.
How are simple life cycles similar to complex life cycles?
Simple versus Complex Life Cycles For some organisms, including humans, individuals in prereproductive and reproductive stages are morphologically very similar to one another. Although they may differ in body size, the two stages have similar appearances, live in similar habitats, and consume similar types of food.
How are animals born and how do they grow up?
Animals that Grow Up ( Simple Life Cycle): Most animals including fish, mammals, reptiles and birds have very simple life cycles: they are born (either alive from their mother or hatched from eggs) they grow up. These animals have three stages — before birth, young and adult.

How is the life cycle of an amphibian different?
they are born (either alive from their mother or hatched from eggs) These animals have three stages — before birth, young and adult. The young are typically similar to the parent, just smaller. The young slowly “grow” to become adults. Amphibians, like frogs and newts, have a slightly more complicated life cycle.
