What is the most complicated life cycle?
What is the most complicated 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. The Lancet liver fluke lives mainly in cows and sheep, but is also found in other herbivorous mammals and, in rare cases, has been known to infect humans.
What is complicated life cycle?
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.
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 platypuses life cycle?
The life cycle of a platypus goes through 4 key stages; The egg stage, the hatching stage, the infant stage and the adult stage.
What is indirect life cycle?
An indirect life cycle is a type of a life cycle wherein a parasite is transmitted from one host to another by using a vector or by an intermediate host of another species. A parasite with an indirect life cycle would therefore require more than one type of host species to complete their life cycle.
What is the life cycle of a protozoa?
During its life cycle, a protozoan generally passes through several stages that differ in structure and activity. Trophozoite (Greek for “animal that feeds”) is a general term for the active, feeding, multiplying stage of most protozoa. In parasitic species this is the stage usually associated with pathogenesis.
Does a grasshopper have a 4 stage life cycle?
They go through “Incomplete Metamorphosis,” in which each stage looks similar to an adult grasshopper but adds a few changes each time the young grasshopper sheds its skin. On the other hand, COMPLETE METAMORPHOSIS has FOUR different stages i.e. the egg, the larva, the pupa and the adult.
What has a 4 stage life cycle?
Birth, growth, reproduction and death represent the four stages of the life cycle of all animals. Although these stages are common to all animals, they vary significantly among species. For instance, while insects, birds and reptiles are born from an egg, mammals develop as embryos inside the mothers’ bodies.
What is the life cycle of a snake?
As per data, majority of the snakes lay eggs. Considering this, the following is a brief highlight about the oviparous snakes, wherein the life cycle comprises three consecutive stages – eggs, juvenile snakes, and adult snakes.
What animal lives longer?
Bowhead whale Bowhead whales
Bowhead whale Bowhead whales, found in the Arctic, are believed to be among the longest-lived animals on earth. According to the World Wildlife Fund, the analysis of eye tissue and stone harpoon tips found in their blubber, bowhead whales can live for more than 200 years.
What is the life cycle of an animal?
Life Cycles of Animals The life cycle of an organism refers to the sequence of developmental stages that it passes through on its way to adulthood. Mammals, reptiles, amphibians, birds, fish, insects and other invertebrates–they each have their own unique way of reproducing life. There is an amazing variety of life cycles within the animal world.
What is a parasitic life cycle?
Parasitic life cycles involve one organism, a parasite, which exploits and benefits from another organism, the host. Generally, the host does not gain from this relationship and often suffers as a result.
What is the lifecycle of filarial worms in humans?
The lifecycle of filarial worms in humans is a complex process, but can roughly be divided into five stages. Adult worms living in the host’s body tissues mate, the female then releases thousands of live microfilariae, which make their way into the host’s lymph and blood systems.
What is the life cycle of a Tasmanian devil?
The life cycle of some sponges includes a process called budding. This occurs when a piece of the adult sponge separates and becomes a new sponge. Tasmanian devils are also marsupials. They live on the island of Tasmania. Their pouch faces backwards–the opening is towards their tail.
