Do You Know About Puffer Fish

Explanation
The answer "Over 120" suggests that there are more than 120 puffer fish species worldwide. Puffer fish are known for their ability to inflate their bodies when threatened, and they are found in various habitats, including both saltwater and freshwater environments. With such a diverse range of habitats and species, it is reasonable to assume that there are over 120 puffer fish species worldwide.

Explanation
Puffer fish should be fed twice a day. This is because they have a fast metabolism and need regular meals to sustain their energy levels. Feeding them only once a day may not provide enough nutrients and could lead to malnourishment. On the other hand, feeding them three times a day might be excessive and could cause overfeeding, leading to health issues. Therefore, the ideal frequency is twice a day to ensure the puffer fish remains healthy and well-nourished.

Explanation
Puffer fish are known to be aggressive. They have a natural defense mechanism where they inflate their bodies to deter predators. Additionally, they have sharp beaks that they can use to bite and attack other fish. These behaviors make them unsuitable for keeping in community tanks with other fish, as they may harm or even kill their tankmates. Therefore, it is accurate to say that puffer fish are aggressive.

Explanation
Puffer fish have four teeth. These teeth are fused together to form a beak-like structure called a "beak." The beak is used by puffer fish to crush and eat their prey, which primarily consists of small invertebrates and shellfish. The beak is extremely strong and can even break through the shells of some mollusks. Puffer fish are known for their ability to inflate their bodies when threatened, making them appear larger and more intimidating to predators.

Explanation
Puffer fish have the unique ability to inflate themselves by taking in water or air, which helps them to deter predators. The correct answer, "2-3 times its size," indicates that a puffer fish can puff up to two to three times its original size. This inflation allows the fish to appear larger and more intimidating to potential threats. However, it is important for the puffer fish not to overinflate, as it can be harmful or even fatal to them.
