Current Question (ID: 13635)

Question:

Consider the following characters: I. Air bladder II. Operculum III. Viviparity The characters present in bony fishes include:

Options:

1. I, II and III
2. I and III only
3. I and II only
4. II and III only

Solution:

Bony fishes are a diverse group of fish that are characterized by the presence of a bony skeleton and a number of other anatomical features. These include an air bladder (or swim bladder) that helps to control buoyancy, and an operculum, which is a bony structure that covers and protects the gills. However, viviparity, or the giving birth to live young, is not a characteristic feature of bony fishes. Some bony fishes may be oviparous (lay eggs) or ovoviviparous (retain eggs inside the body, but do not provide any additional nutrition to the developing embryo).
