Larval stage of mollusks and annelids?
Glochidium and veligar which are types of trochophore larvae are larval forms of mollusca .
Are all amphibians carnivores?
Pretty much all amphibians are carnivores. Many of them eat plants at some point in their lives, but most live on other animals. Some examples of amphibians include frogs, toads, salamanders, and newts. They all need to live near water because they reproduce in water and live the first part of their life there.
What yellow larval worms eat amaranth leaves in Florida?
Bougainvillea looper caterpillars appear among the yellow larval worms that eat amaranth leaves in Florida. The larval stage grows up to be a fast-flying brown or gray moth. The egg, larval, pupal and mature stages of Disclisioprocta stellata generally prove not to be problematic since only the caterpillar preys upon the leaf edges of amaranth, boungainvillea, devil's claw and pokeweed.
Is cnidarians asexual or sexual?
yesMarine bivalves reproduce by releasing prodigious numbers of eggs and sperm into the water, where external fertilization occurs. The fertilized eggs then float in the surface Within 48 hours after fertilization, the embryo develops into a minute, planktonic, trochophore larvae. This stage is followed by another larval form, the veliger, which settles to the seabed and transforms into an adult. In freshwater bivalves, the eggs are retained in the gill chambers of the female, where they undergo fertilization and develop into a peculiar larval form, the glochidium. Upon its release, the larva attaches to passing fish, and lives as an ectoparasite for several weeks before settling.From: http://science.jrank.org/pages/944/Bivalves.html
Do dragonflies need water to live?
Yes, their larval stage is entirely aquatic.
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.
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.
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.
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.
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 important adaptation allows a reptile to live and reproduce on land while an amphibian must return to water to reproduce and complete the life cycle?
Reptiles do not have a larval based reproduction. They are hatched (and in a few species live birth) already in the adult phase. Amphibians must go through metamorphose to get to their adult phase.
How do Zebra Top Shells reproduce?
The zebra top shell is in the family of Trochidae and most Trochidae reproduce by expelling sperm and eggs into the water for external fertilisation. In other species, the female lays a gelatinous egg-mass which is the early stages of larval development.
What does octoupus eat?
Young octopus eat copepods, larval crabs and larval seastars. Adults eat crabs and fish.
Do reptiles have a larval stage?
No reptiles do not have a larval stage.
Do starfish have babys?
Interestingly, the Starfish is capable of both sexual and asexual reproduction. Which is to say they can have babies both with a partner and without one. Starfish often reproduce by what's called "free-spawning" in which they release their gametes into the water where they hopefully are fertilized by gametes from the opposite sex. Starfish most probably gather in groups when ready to spawn, releasing chemical indicators to let other starfish know of their readiness. Starfish spawn are like insects, going through multiple stages of development and larval stages. Unlike adults, larval forms of starfish have distinct left and right sides.
