Sea Dragon Leviathan

"'We're gonna need a bigger boat.'"

The Sea Dragon Leviathan, or simply just the Sea Dragon, is a work-in-progress creature that will be implemented in a future update, possibly some time after the release of the Sea Emperor.

Compared to the Sea Emperor, the Sea Dragon Leviathan is shown to be more than twice its length, thus claiming the title of being the largest life form in the game, formerly belonging to the Reaper Leviathan and originally the Reefback.

Appearance
The overall appearance of the Sea Dragon Leviathan represents a chimera of different animals such as cephalopods, crocodilians, primates, crustaceans, amphibians, and sharks. It also bares a high resemblance to the Sea Emperor and Lava Lizard.

Its skin is covered in reptilian scales while its underbelly is decked with armored plating and osteoderms. It's main color scheme is camo green with its secondary color being orchid. The underbelly is mainly dark bluish grey in color. On the sides of the underbelly are small openings that glow a fiery orange and run down to the rear. When around the rear, the 'line' curves above the underbelly and onto the camo green skin.

The rear of the Sea Dragon Leviathan sports six tentacles surrounding a larger tail-like tentacle. Each tentacle has a squid-clubbed tip that ends with a hook, with the 'palm' being orchid. They also sport tiny, bioluminescent clusters at their base areas that glow blue and orange. These only appear on the under-portion of the tentacles, which is the same coloration as the underbelly, being dark bluish grey. The lower tentacles appear to longer than the upper tentacles.

The head is exoskeletal and dinosaur-like in appearance, with the mouth being similar to that of a Giganotosaurus and modern crocodilians. The shape of the skull and jaw is almost cubic in shape, having sail-like extensions on each side of the chin and snail eyestalk-like antennae on the tip of the snout that glow light orange at the 'eyes'. The nostrils appear below each stalk. It has two pairs of light orange eyes on each side of the head, with one eye behind another. The mouth contains sharp, crocodilian-like teeth, with a tooth count of eighteen upper and lower teeth. The four upper-mid teeth are embedded in the skin. The back of the neck is plated while a set of osteoderms run down the top and a pair run down the sides of the jaw.

The arms are almost human-like in appearance with rows of osteoderms that point upwards on the arm proper and downwards on the forearm. Both arms have a pattern of orchid spots and stripes that run down to the wrist, which is plated in a way similar to knight armor. The hands have orchid webbing between all four fingers. Each finger ends in nail-like claws that are beige in color. There is also a small, fifth finger on the back of each forearm, being closer to the wrist than the elbow.

There are two pectoral fins on its head and a dorsal fin on its back. The structures of the fins consist of three rod-like extensions webbed together with orchid skin. The top extension is always the shortest while the bottom extension is always the longest. When connecting each extension, the skin starts at the tip of the above extension and ends around the top half of the extension below. There is an orchid flap of skin on the bottom of each pectoral fin and webbing connects the lower extension of the fin to the back.
