Zebra Shark Overview
Appearance
The Zebra Shark (Stegostoma fasciatum) is a distinctive and striking marine species. It features a sleek, elongated body with a cylindrical shape. Its skin is adorned with bold, dark brown stripes that resemble a zebra’s pattern. These stripes cover the entire length of its body, including its tail.
Origins And Evolution
The Zebra Shark (Stegostoma fasciatum) has origins dating back to prehistoric times, with its evolutionary history stretching over millions of years. It belongs to the carpet shark family and is believed to have evolved from ancient shark ancestors during the Cretaceous period. Its distinctive appearance with zebra-like stripes is the result of gradual adaptations to its environment.
Over time, these sharks have thrived in the warm, tropical waters of the Indo-Pacific region, including the western Pacific Ocean and the Indian Ocean. They have maintained their unique appearance and foraging behavior, which includes hunting for small fish and invertebrates on the ocean floor.
Behavior and Lifestyle
Zebra Sharks (Stegostoma fasciatum) are nocturnal predators, typically resting on sandy seabeds during the day and becoming active at night. They have a relatively slow and methodical swimming style.
These sharks are known for their scavenging behavior, using their strong jaws and sharp teeth to crush and feed on crustaceans, mollusks, and small fish. Sharks are generally solitary, although they may be found in small groups occasionally.
