Animals Associated With Indirect Development Some echinoderms, amphibians and insects undergo indirect development: butterflies, dragonflies, frogs and so forth. The larva or young form of these creatures often fulfill a different ecological niche than the adult animal does.

Are fish direct or indirect development?
This indirect development is typical for fish with numerous small eggs, little yolk and, in most cases, no parental care; it is especially common in pelagic marine species. With increasing parental care — from egg scatterers to brood hiders to external and internal bearers — the eggs become yolkier and less numerous.
Is Turtle development direct or indirect?
Turtles have direct development… no larva! Turtles hatch looking like miniature versions of adults. Living reptiles most closely related to dinosaurs.
In which of the following indirect development takes place?
Indirect development (larval stage) is found in mollusca, echinodermata and hemichordata.
What is indirect development zoology?
Indirect Development: It is a type of development an animal born is different from the adult form. ... The larva undergoes a process of metamorphosis to become its adult stage. Animals that experience indirect development have very little yolk and due to the small amount of yolk, the larva develops and hatches rapidly.
Are humans direct or indirect development?
Direct development is the process of development in which any larval stage is absent, which means metamorphosis is not present, offsprings are produced directly. The new borns are similar to their parents in morphology and feeding habits. For e.g. Human beings, Birds, Fishes.
Is development direct or indirect in platyhelminthes?
Most free-living flatworms (i.e. Platyhelminthes excluding the parasitic Neodermata) are directly developing, whereas in polyclads, also indirect developers with an intermediate free-living larval stage and subsequent metamorphosis are found.
Do amphibians have direct development?
Direct development is a widespread alternate reproductive mode in living amphibians that is characterized by evolutionary loss of the free-living, aquatic larval stage. Courtship, mating, and oviposition occur on land, and the terrestrial egg hatches as a fully formed, miniature adult.
What is direct development in frogs?
Many frogs have eliminated the tadpole from their life history—a process termed direct development. That evolution enables these frogs to reproduce on land; they never have to go into the water. Direct developers, like this Eleutherodactylus coqui from Puerto Rico, form limbs and frog-like heads early (a, b).
In which animals fertilization is external with indirect development?
It occurs in most of the invertebrates and amphibians. Thus fertilization which occurs outside and development involves larval stages is referred as external fertilization with indirect development.
Does Mollusca have indirect development?
Molluscs are oviparous. The development is either direct or indirect (metamorphosis). When the development is indirect, it includes a characteristic larva, veliger, trochophore and glochidium.
Do grasshoppers have direct development?
Hemimetabolous insects, such as cockroaches, grasshoppers, and dragonflies, go through gradual changes as they slowly develop from juvenile forms, called nymphs, to the adult form. These changes often include the budding and growth of their wings.
What type of development do arthropods have?
Arthropods (and other animals) that undergo direct development do not have a free-living larval form. Rather, the parent animals care for the babies, usually by brooding or encapsulating them (in eggs), and the young have the same form as the adult, but smaller. A small version of the adult is sometimes called a NYMPH.
Why Arthropoda is the largest phylum?
Why is arthropoda the largest phylum? Phylum arthropoda includes 80% species of animals. These species evolved certain adaptive features over the years to survive the changing climatic conditions and form the largest phylum in the animal kingdom.
What is indirect development in sponges?
In this type of development, embryo develops into a mature individual without involving a larval stage. It this type of development, sexually-immature larval stage is present.
