Common name: Zebra Shark

General Information

The Zebra Shark, scientifically known as Stegostoma fasciatum, is a unique and fascinating species often admired for its distinctive appearance and gentle demeanor. Named for the juvenile's zebra-like stripes, which fade into spots as they mature, this species has captured the interest of both aquarists and marine biologists alike. Despite its large size, the Zebra Shark is known for its docile nature, making it a popular choice for large public aquariums.

In the wild, Zebra Sharks play a crucial role in maintaining the health of coral reef ecosystems. They are often found resting on sandy bottoms during the day and become more active at night, searching for prey. Their ability to breathe while stationary makes them particularly interesting to observe in captivity.

Care

Zebra Sharks require a very large aquarium due to their size and active nature. They thrive in environments that replicate their natural habitat, which includes sandy substrates and plenty of open swimming space. While they are relatively hardy, maintaining stable water parameters is essential for their health. They are best suited for experienced aquarists or public aquariums due to their specific care needs and space requirements.

Diet and Feeding

In the wild, Zebra Sharks are carnivorous, feeding on mollusks, crustaceans, and small fish. In captivity, they should be offered a varied diet that includes fresh or frozen seafood such as shrimp, squid, and fish. Feeding should occur several times a week, ensuring the portions are appropriate for their size.

Behavior and Compatibility

Zebra Sharks are generally peaceful and can be kept with other large, non-aggressive marine species. They are solitary creatures but can sometimes be seen interacting with other species in a large enough environment. Care should be taken to avoid housing them with overly aggressive or territorial species.

Reproduction

Breeding Zebra Sharks in captivity is challenging and has been achieved primarily in large public aquariums. They are oviparous, meaning they lay eggs, which the female deposits in a secure location. The eggs have a tough casing and take several months to hatch. Raising the young requires specific conditions and a separate rearing tank.

Health and Common Issues

Zebra Sharks can live for 20-25 years in captivity with proper care. Regular monitoring of water quality and diet is crucial to prevent common health issues such as skin infections or parasites. Ensuring a stress-free environment with minimal disturbances will promote their well-being.

Habitat

Zebra Sharks are found in the Indo-Pacific region, inhabiting coral reefs and sandy flats at depths of up to 62 meters (203 feet). They prefer warm, tropical waters and are often seen resting on the ocean floor during the day, becoming more active at night.

Conservation Status

According to the IUCN Red List, Zebra Sharks are classified as Endangered due to habitat loss and overfishing. Conservation efforts are focused on protecting their natural habitats and regulating fishing practices to ensure their survival.
