How do cypris reproduce?
Cypris, the larval stage of barnacles, reproduce through a process called external fertilization. Males release sperm into the water, which then fertilizes the egg of a nearby female. After fertilization, the eggs develop into nauplius larvae before eventually settling and transforming into adult barnacles. This reproductive strategy allows for a wide dispersal of offspring in marine environments.
What are larval food plants?
Larval food plants are specific plants that caterpillars feed on during their larval stage. Different species of butterflies and moths have specific larval food plant requirements, with some being very selective about which plants they can feed on. Providing the appropriate larval food plants is crucial for the successful development and survival of caterpillars.
How do cyclostomata reproduction?
Cyclostomata, which includes jawless fish like lampreys and hagfish, typically reproduce through external fertilization. Most species undergo spawning, where females release eggs into the water, and males simultaneously release sperm to fertilize them. This process often occurs in freshwater or marine environments, depending on the species. Some lamprey species also exhibit a more complex life cycle, with larval stages that live in sediment before transforming into adults.
How do conus figulinus reproduce?
Conus figulinus is a species of cone snail, which reproduces sexually. They release eggs and sperm into the water, where fertilization occurs. The fertilized eggs develop into larval stages before settling on the ocean floor and growing into adult snails.
Larval stage of mollusks and annelids?
The larval stage of mollusks is called a trochophore, which is a free-swimming, ciliated larva that eventually develops into the adult form. For annelids, the larval stage is called a trochophore or a nectochaete, which also metamorphoses into the adult form after a period of growth and development.
Does the larva stage resemble the adults?
No larval stage is the maggot (as in housefly) then they pupate and the adult emerges after metamorphosis. Those insects where the nymphs adults look like adults have only a 3-stage cycle egg, nymph, adult, with no larval or pupal stage.
Do reptiles have a larval stage?
No, reptiles do not have a larval stage. Unlike some amphibians and insects, reptiles hatch from eggs in a form that resembles miniature adults. They do not undergo metamorphosis like amphibians that have larval stages such as tadpoles.
What animals reproduce by egg-nymph-adult?
Roaches, silverfish, bedbugs amongst other things. Some insects the nymphs resemble the adults & there is larval or pupal stage, for example-fleas-egg, larvae, pupae, adult.
How is the life cycle of mammal different from that of an insect?
Insects typically have short lives as adults, but may spend a very long time in the larval or egg state. Mammals generally live longer than insects, and the majority reproduce through live birth. Mammals typically live the majority of their lives as adults.
Does the larva stage resemble the adult?
No larval stage is the maggot (as in housefly) then they pupate and the adult emerges after metamorphosis. Those insects where the nymphs adults look like adults have only a 3-stage cycle egg, nymph, adult, with no larval or pupal stage.
Are Snails the final host in the life cycle of blood fluke?
The Final Stage of a parasitic life-cycle is the stage in which it reproduces sexually. So, in the Fluke's life-cycle, the cow or human host where the larval forms grow into sexually mature adults and reproduce.
What are jellyfish litter size?
Jellyfish can reproduce sexually and asexually. There are around 100 spawn per litter when jellyfish reproduce, and the youngest spawn are known as larval planulae.
Why do cockchafers only come out in may?
Cockchafers, or May bugs, typically emerge in May as this aligns with their life cycle, which involves several years of development in the larval stage beneath the soil. The warmer temperatures and increased availability of food sources during spring trigger their metamorphosis into adults. This timing allows them to mate and reproduce when conditions are optimal for their survival. Consequently, their seasonal emergence is closely tied to environmental cues that signal the onset of spring.
Do sow bugs have larva?
No, sow bugs do not have larvae. They are a type of terrestrial crustacean and reproduce by laying eggs, which hatch into miniature versions of the adults, known as juveniles. These young sow bugs resemble their parents right from the start, rather than going through a larval stage like some other organisms.
How do you know a salamander is a amphibian?
They have a larval and adult life, have moist skin, larvae have gills while adults have lungs, and they perform amplexus to mate.
What is a young housefly called?
A young housefly is called a maggot. Maggots are the larval stage of the housefly before they pupate and emerge as adults.
When a maggot grows up what does it become?
A maggot grows up to become a fly. Maggots are the larval stage of flies, which eventually pupate and emerge as adults.
