➡Because there are no fossil agnathans to confirm the possession of the endostyle (including the recently discovered Devonian lamprey, which does not seem to have included the larval stage), the second scenario seems equally plausible (Hardisty 1982; Gess et al. 2006).

Answer:

Hagfish belonging to the class Myxini does not have any larval form and develops directly from eggs.

Explanation:

Cyclostomes comprise the living lawless fishes- the lampreys and the hagfishes.

These are marine fishes that produce slime and are the only living animals that possess no vertebrae( rudimentary vertebrae present) but have a skull.
