A black bump on your cat's chin could be caused by a variety of factors, including acne, allergies, infections, or even a tumor. It is important to have your cat examined by a veterinarian to determine the exact cause and appropriate treatment.
The long things under a betta fish's chin are called "pectoral fins." These fins are used for steering, balancing, and maneuvering while swimming. Betta fish also have unique elongated fin shapes that contribute to their graceful movement and vibrant appearance. The pectoral fins can be particularly prominent in male bettas, enhancing their display during courtship or territorial displays.
A bump on the chin after being hit is primarily due to localized swelling, known as a hematoma. When the skin and underlying tissues are injured, blood vessels can break, causing blood to accumulate in the surrounding tissues. This results in inflammation and swelling, which manifests as a bump. Additionally, the impact can also cause soft tissue damage, further contributing to the swelling.
