What is the difference between monecious and dioecious in mollusks and annelids?
monecious is when it has male and female reproductive organs in the same organism.
Are leaches bugs?
Leeches are not bugs (insects). Leeches are animals, segmented worms in the same phylum (Annelida) as earthworms. Although insects do have a larval (worm-like) stage of their development, worms are not related to insects. After the larval stage, insects later develop legs and exoskeletons. Leeches and worms have neither exoskeleton nor legs at any stage of their lives. The larval stage of insects leads to the common misconception that they are related to worms, but this is not the case.
What kind of baby fish are clear with an orange tail fin?
I'm sorry, but there are too many fish, that when they are in their larval stage, they have that same appearance. You will have to wait until the fish is in its post-larval (a few weeks to a month or two after hatching) or juvenile stage (near adult) to be able to tell what kind of fish it is.
Does larvae eat more than adult insects?
Yes. In general the larval stage eats large quantities of food in order to grow. The adult stage stays the same size.
What characteristics do tunicates have in common with chordates?
Tunicates share the same larval stage with other chordates, possessing a notochord, dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail. These characteristics are key similarities that classify tunicates within the chordate phylum.
Why do some people say that a pollywog and the tadpole are the same while some say they are different?
Both polliwog and tadpole are different words for the same thing. Both words refer to the larval stage of both frogs and toads.
Are caterpillars annelids?
No, they are arachnids. Annelids are segmented worms.
Are squids and octopuses the same animal?
.they are all in the phylum mollusks. This means they are related to taxonomers.
What does hemichordata mean?
same as protochordata ----------------------------------------------------------------------------------------- The hemichordata are a a small phylum of marine invertebrates that have a vertebrate like hollow nerve cord and an echinoderm like larval stage. The "hemi" prefix means "half".
What is the similarity between complete and incomplete metamorphosis?
Complete metamorphosis is a type of metamorphosis characterized by four frantically different stages: egg, larva, pupa and adult. Gradual metamorphosis is a type of metamorphosis in which an egg hatches into a nymph that resembles an adult, and which has no distinctly different larval stage. They are alike because they both turn into the same thing at the end, an adult. Even though gradual metamorphosis has no larval stage, or it is different, they both turn into an adult.
Why does a tadpole develop into a frog?
Essentially, the larval stage in a species' development cycle renders a specimen as a different type of lifeform than the adult stage does. Tadpoles resemble small fish such as minnows much more than adult frogs so they are labelled as larvae. Mammals look pretty much the same throughout life, so they are not said to have a larval stage. Larvae feed rapidly to fuel the metamorphosis into adulthood. See the related Wikipedia link for a much more detailed explanation.
Are frogs considered mollusks?
they are all in the same category
