Sea cat

A sea cat, also known as a sea lion, was a magical beast that combined the features of a lion and a fish. It was a ferocious predator of the seas.

Description
The sea cat bore the head and forepaws of a lion but a body and tail similar to those of a fish or of a porpoise of small whale. It had a mane of silky hair running from the top of its head and down its back to its tail flukes. They were depicted as having either tan fur and fish-like scales or green skin and reptilian scales.

A full-grown sea cat grew to a length of 12 feet (3.6 meters) or even 15 feet (4.5 meters), and it weighed up to 800 pounds (360 kilograms).

Abilities
Sea cats were talented natural swimmers, though not as good as sea horses.

Being mammalian, a sea cat apparently risked drowning if it stayed too long underwater. It could hold its breath underwater for about 10 minutes. On the other hand, sea lions were also reported to have gills, allowing them to extract oxygen from water. The sea lion's thick scales had a water-proofing ability, allowing it to survive out of water for up to 24 hours, after which time its gills dried out and no longer functioned. If the sea lion was constantly supplied with water in its mouth, it could survive for a full week. After this time, its scales dried and cracked, permitting disease to take hold, while the sea lion typically starved.

The roar of a sea lion carried for up to 10 miles underwater.

The sea cat could track by scent.

Behavior
Having only animal intelligence, sea cats were highly aggressive and territorial. They would assault any creature, no matter how large or dangerous, that trespassed in their domains.

Combat
When they saw food or a threat, sea cats attacked on sight, with pairs or prides working together to overcome an opponent. They were possessed of awesome courage and would fight to the death, even against much larger and much deadlier foes.

They could attack with either claws or fangs, but would only fight one foe at a time. If they got both paws on a creature, they latched on tight, rending and mauling their victim. It had a tough scaly hide for defense, and the thick mane provided additional protection to the head region.

Ecology
Although an uncommon aquatic creature, sea cats were generally found in shallow coastal waters. They made their lairs in underwater caves and even in wrecked ships. They were active during daylight hours.

They were carnivorous and would hunt and eat almost any kind of creature they could catch, typically fish, aquatic mammals like dolphin or whale, sea birds, and dinosaurs. They would even take herd animals drinking at the shore. They were even known to use their paws to drag themselves up a beach in search of prey, unafraid to go up to 140 feet (40 meters) inland, though this was rare.

Sea cats had a special enmity for sharks, often going out of their way to hunt them down and attack them. They had little trouble killing most sharks. However, they never ate the carcass, and seemed to find the taste of shark flesh disgusting. Why this was so is unclear. Although some sages supposed this was a conflict fought between lesser nature deities, the more mundane reason was that it was a result of natural competition between two predators occupying the same ecological niche.

Among sea cats, both males and females cared for their young and hunted for food. Males were superior hunters, however, unlike convention lions.

If not travelling alone or in pairs, sea cats gathered into packs called "prides". Numbering up to twelve individuals, they were structured like prides of lions on land, with the strongest (that is, the most resilient) sea cat as the leader.

Occasionally, sea cat prides who wandered close together formed temporary alliances with which to handle especially dangerous creatures that trespassed in their territories. These alliances lasted only until the opponent was slain, and their territorial nature reared again. The resident leader would refuse to allow the visiting pride to share in the meal, and the two pride leaders might fight for dominance. If the resident leader won, then the visitors left without any meat. If the visiting leader won, the visitors would take first picks of the meat then leave the rest to the resident pride. However, the defeated resident leader would be weakened and likely deposed, even slain, by one of their own pride.

Reputation
Sea lion attacks caused fear among coastal dwellers, more so than a shark attack, owing to their potential to strike inland. Still, they were considered a minor danger, comparable to sharks but not even close to, say, krakens. Sea lions were the symbol and namesake of the Lions' Dynasty of Tethyr, because of a tale of how Prince Nearel used a magic horn to summon a pack of them to defend against a band of assassins.

Uses
One could keep a sea lion alive in captivity, but it was extremely difficult. Restrictions on its domain were psychologically damaging to the animal, and it would eventually die. However, assuming one could preserve it and train it, and survive, sea lions were known to be the most loyal and powerful mounts available on or under the waves. They were especially effective as guardians and hunters—the long range of their roar gave sufficient time for their masters to prepare for an assault or send reinforcements.

Regions
Sea lions were found in the seas of Kara-Tur, such as in the waters around Koryo. Sea lion prides menaced sailors in the Straits of Koryo between the island of Saishu and the mainland Koryo Peninsula, but the fishermen of In'ani and Ansong, on either side of the straits, had eliminated these prides before 1357 DR. This was one of the reasons they were claimed to be the best fishermen in the world. However, one pride continued to harass shipping around In'ani itself, so governor Dan Zor sought adventurers to destroy them.

Background
The sea cat, formerly known as a sea lion, is likely based on the sea-lion figure of heraldry, commonly associated with the Philippines. Similar to the heraldic sea-lion is the Merlion icon of Singapore.
