Black Banded Cat Sharks can be distinguished by their concave posterior margined dorsal fin. Juveniles have dark transverse bands with some dark spots. These sharks are nocturnal animals and can survive out of the water for up to 12 hrs. They have barbels, which are sensory organs that look like whiskers. Hence the common name "cat shark". However, they are not true members of the catshark family, and are more closely related to the nurse and whale sharks.

The California Stingray, also known as Haller's Round Ray, is a bottom dwelling ray with a brown body and yellow spots. It has a poisonous tail and should be treated with extreme care. Generally found in the coastal waters of the Pacific, the California Stingray thrives on benthic invertebrates and is not necessarily reef safe. They will need a tank of at least 180 gallons to provide them enough space and should only be kept by experience aquarists.

Grey Smooth Hound Sharks originate in temperate waters of the eastern Pacific, primarily from California down to Mexico. While they are active fish that swim most of the time, they tend to stay near structures and the ocean floor in order to avoid larger more aggressive shark species. Grey Smooth Hound Sharks have sharp teeth and are true sharks, they are not harmful to humans and are highly unlikely to bite a human unless provoked. This species is considered suitable for expert marine aquarium hobbyists with very large aquariums due to their relatively small size (3 to 4 feet) and active but slower swimming style.
