Solution:

Veliger larva is found in the phylum Mollusca.
In Cnidaria, Hydra does not have any free larval stage in the development.
In Echinodermata, larva is named as bipinnaria in star fishes, ophiopluteus in brittle stars, echinopluteus in sea-urchins etc.
In Arthropoda, development can be direct (without larval stages) or indirect (with larval stages) may involve metamorphosis.
