Which one of the following groups of animals is correctly matched with...
Reptiles usually posses 3-chambered heart but crocodiles are an exception with 4-chambered heart. Not all chordates have a mouth with upper and lower jaw. Egg laying mammals include duck-billed platypus. Chondrichtlyes (cartilaginous fishes) are the fishes that have cartilaginous endoskeleton. There is no exception to this.

Which one of the following groups of animals is correctly matched with...
Chondrichthyes, commonly known as cartilaginous fishes, possess a cartilaginous endoskeleton. This characteristic feature is unique to this group of animals and is not found in any other group without exception.
Explanation:
1. Chondrichthyes:
- Chondrichthyes are a class of jawed fishes that includes sharks, rays, and chimaeras.
- One of their defining features is the presence of a cartilaginous endoskeleton, which means their skeleton is composed of cartilage rather than bone.
- This cartilaginous endoskeleton provides flexibility and lightness to their body, allowing them to move more easily in water.
- This feature is not present in any other group of animals without exception.
2. Reptilia:
- Reptiles, including snakes, lizards, turtles, and crocodiles, possess a 3-chambered heart with an incompletely divided ventricle.
- However, there are exceptions within this group. For example, crocodiles have a 4-chambered heart, which is a more advanced characteristic compared to other reptiles.
- Therefore, the characteristic feature of a 3-chambered heart with an incompletely divided ventricle is not true for all reptiles.
3. Chordata:
- Chordata is a phylum that includes animals with a notochord, a hollow nerve cord, pharyngeal slits, and a post-anal tail at some point during their life cycle.
- While many chordates possess a mouth with an upper and lower jaw, there are exceptions to this feature. For example, jawless fishes such as lampreys and hagfishes do not have jaws.
- Therefore, the characteristic feature of possessing a mouth with an upper and lower jaw is not true for all chordates.
4. Mammalia:
- Mammals, including humans, possess mammary glands and give birth to live young ones.
- However, there are exceptions within this group. For example, monotremes (such as platypus and echidna) are mammals that lay eggs instead of giving birth to live young ones.
- Therefore, the characteristic feature of giving birth to young ones is not true for all mammals.
In conclusion, the group of animals correctly matched with its characteristic feature without any exception is Chondrichthyes, which possesses a cartilaginous endoskeleton. This feature is unique to this group and is not found in any other group without exception.
