The Mars Ocean Hypothesis is a hypothesis that nearly a third of the surface of Mars was once covered by an ocean earlier in its history. The ocean, which is called Oceanus Borealis, would have filled the Vastitas Borealis basin in the northern hemisphere. The Vastitas Borealis is 4–5 km (2.5–3 miles) miles below the planetary elevation. Oceanus Borealis dried up 3.8 billion years ago. Early Mars would need a warmer climate and thicker atmosphere to let liquid water stay at the surface.

Whitetip reef shark
The Whitetip reef shark ("Triaenodon obesus"), is a species of requiem shark, and the only member of its genus. The whitetip reef shark gets its name because of the white tips on its first dorsal fin and caudal fin. This shark has a slim body, with a short, wide head, a blunt, flattened snout, and oval-shaped eyes. The body is dark grey to brown in colour, and the underside is white. The whitetip reef shark is widely distributed across the entire Indo-Pacific region, and is common along coral reefs, but is also found over sandy flats, in lagoons, and near drop-offs to deeper water. This species of shark is viviparous, giving birth to 1-5 pups after a gestation period lasting up to 12 months. The whitetip reef shark is currently listed as Near Threatened by the IUCN.
The whitetip reef shark has a slim body, and has a short, wide head. The snout is flattened and blunt, and has large flaps of skin in front of the nostrils. The eyes are small and oval-shaped, and have vertical pupils. Along with the mouth which slants downwards, the visible brow ridges give this shark a permanent "disgusted" expression to its face. The first dorsal fin is located well behind the pectoral fins. The second dorsal fin is large, but smaller than the first dorsal. The pectoral fins are wide and triangular in shape. The anal fin is about as large as the second dorsal fin. There is no interdorsal ridge (ridge between the two dorsal fins), and there are no lateral keels on the caudal penduncle.
The whitetip reef shark earns its common name for the white tips on the first dorsal fin and upper caudal fins. The body is dark grey to brown, and the underside is white. Small dark spots are sometimes present over the entire body. The remaining fins may also have white tips, but not always. The whitetip reef shark is sometimes confused with the Silvertip shark due to their similar appearances. However, the silvertip shark is a much heavier species, and has a large first dorsal fin and a much smaller second dorsal fin. Also, its caudal fin is lined with white, rather than tipped, as with the whitetip reef shark.
The whitetip reef shark is quite a small species of shark, growing to a maximum length of just under 7 feet (2.1 metres), however, individuals are rare at lengths over 5.2 feet (1.6 metres). Males mature at about 3.4 feet (1.04 metres) long, and generally reach lengths of up to 5.5 feet (1.7 metres). Females reach maturity at 3.4-3.6 feet (1.04-1.1 metres), and grow to at least 5.2 feet (1.6 metres). Whitetip reef sharks weigh a maximum weight of 18 kg.
The whitetip reef shark is widely distributed across the entire Indo-Pacific region. In the Indian Ocean, it is found from northern KwaZulu-Natal, South Africa to the Red Sea and the Indian subcontinent, including Madagascar, Mauritius, the Comoros, the Aldabra Group, the Seychelles, Sri Lanka, and the Chagos Archipelago. In the western and central Pacific, it occurs from off southern China, Taiwan, and the Ryukyu Islands, to the Philippines, Southeast Asia, and Indonesia, to northern Australia, and is also found around numerous islands in Melanesia, Micronesia, and Polynesia, as far as Hawaii to the north, and the Pitcairn Islands to the southeast. In the eastern Pacific, it occurs from Costa Rica to Panama, and off the Galápagos Islands.
The whitetip reef shark is found mainly at coral reefs, but it is also found over sandy flats, in lagoons, and near drop-offs to deeper water. They prefer very clear water and rarely swim far from the bottom. This species is most common at a depth of . Sometimes, they may enter water less than 1 metre deep, and there is a record of a whitetip reef shark being captured from a depth of in the Ryukyu Islands.
The whitetip reef shark is usually seen swimming in clear waters along coral reefs, and has been reported at depths to up to 1,083 feet (330 metres). This species rarely swims to the surface, and is capable of lying motionless on the bottom for long periods of time. During daylight hours, whitetip reef sharks form large groups in caves, sometimes appearing stacked up like a pile of logs. The same sharks often return repeatedly to the same cave for long periods of time, changing location only periodically. The whitetip reef shark is most active throughout the night.
During the night, the whitetip reef shark becomes very active, and searches for prey along the bottom. When the shark finds a prey, it chases the prey into a crevice or small cave, trapping it. The slim body, blunt snout, and tough skin helps the whitetip reef shark hunt successfully in these small spaces. It feeds mainly on bony fish, including eels, squirrelfish, snappers, damselfish, parrotfish, surgeonfish, and triggerfish. It also eats octopuses, crabs, and lobsters.
