What is the difference from meroplankton and holoplankton?
Meroplankton are organisms that spend only a part of their life cycle in the planktonic stage, typically as larvae, before settling into a benthic or nektonic lifestyle; examples include the larvae of crabs and fish. In contrast, holoplankton are organisms that remain planktonic for their entire lives, such as jellyfish and copepods. Essentially, the key difference lies in the duration of their planktonic existence, with meroplankton being temporary and holoplankton being permanent inhabitants of the plankton community.
Which phylums have trocophore larva?
Phyla Mollusca and Annelida have trochophore larvae. These larvae are characteristic of the early stages of development of certain marine invertebrates, where they display a ciliated, free-swimming, planktonic form.
Is a starfish an animal plankton?
Sure, starfish larvae are planktonic. Adult starfish are not.
What are the advantages and disadvantages of the survival for planktonic larvae?

What is the role of crustaceans in marine food webs?
They are scavengers, their planktonic larvae are a big food source.
What do arrow worms eat?
Arrow worms primarily feed on small planktonic organisms such as copepods, krill, and other tiny invertebrates. They are active predators, using their well-developed grasping spines to capture their prey. Some species are also known to feed on fish eggs and larvae.
How do angel flame fish reproduce?
The species is an Egg-Scattering fish, with Planktonic eggs and larvae. It has not yet been successfully bred in the aquarium.
Is a dragonfly larva a herbivore?
No, dragonfly larvae are not herbivores as they eat other species' larvae or tadpoles.
How a young starfish may differ from the adult starfish?
Young starfish, or larvae, differ significantly from adult starfish in both appearance and lifestyle. While adults exhibit the characteristic radial symmetry and distinct arms, young starfish are often bilaterally symmetrical and may have a more gelatinous, free-swimming form. Additionally, the larvae primarily float in the water column, relying on plankton for nourishment, whereas adults are benthic, feeding on small invertebrates and detritus on the ocean floor. This transition from a pelagic to a benthic lifestyle marks a significant developmental change as they mature.
The larvae that may be the link between vertebrates and invertebrates in evolution is what?
Maybe an ammocoete larva.
What are baby sea stars called?
Baby sea stars are called "larvae" or "planktonic juveniles" before they mature into adults.
What is the lobsters primary means of locomotion?
Because the adult lobster is benthic the primary means of locomotion are the walking legs or pereiopods. Occasionally, depending on climate and storm conditions, they group into chains for long-distance migration, a configuration which reduces drag and makes long distance travel more efficient. As larvae, lobsters are planktonic and live near the ocean surface, drifting with the current; in their postlarval stage they can swim.
