Yes, it is possible that a fish can drown. The reason for drowning might be the suffocation caused due to low dissolved oxygen, the temperature of the water, overcrowding of living species, or the impurities present in the water. Well if you are wondering about the sinking of fish in the water, then the answer is no because the density of fish is similar to the water and they have the ability to regulate their average density to swim at different depths without spending much energy.

In the case of fish, taste buds are not limited to the tongue or the mouth area but they can be found on the other parts of their body. They have the ability to taste their food without actually swallowing it. Proper functioning of the taste buds require moisture and the fish is always surrounded by water all time. Therefore, their external skin is always moist and have taste buds on their body. The catfish has the highest number of taste buds (about 680,000) compared to other animals. Even humans have only 5,000 taste buds in their mouth.

First, starfish will align the prey such as mussels to the center using their arms and tube feet. Now the starfish will start feeding by extending its cardiac stomach out of its mouth over the prey. This cardiac stomach will release digestive enzymes on the prey and then will start absorbing the prey’s body. The food gets partially digested externally and the cardiac stomach is drawn back into the body. The further digestion of food occurs in the second stomach i.e, pyloric. In this way, starfish eats its prey.

Yes, most of the fish do have tongues. Fish tongues are bony structures that are located on the floor of the mouth, also known as basihyal to protect the ventral aorta.

No, fish cannot survive in milk. Fish cannot breathe properly in milk due to low dissolved oxygen and the presence of impurities in milk. Therefore, fish may drown in milk within a few minutes.

Even a freshwater fish cannot survive in salt water and vice versa. Have you ever wondered, can fish swim and survive in milk, coke, beer, or some other liquids other than water. Before we jump
