Rostrocerovenator letaligibbas
Nesting Site: Sandy shorelines in Zone F
Hunting Site: Oceans of Zone 3
A descendant of Rostrovenator rostrus, this aquatic wyvern has taken its adaptations even further due to the response of increased competition in Zone 3. Rostrovenator letaligibbas has grown a longer snout and a longer tail for swimming at faster speeds and for catching more prey. Adults grow to one-hundred eighty-five centimeters (185 cm) in length and newborn calves are around forty-five to fifty centimeters (45-50 cm) in length from snout to tail. The feet have also become webbed for better propulsion in the water, and the tail fins have become more defined. The air sac has grown slightly larger to maintain the ten (10) minute breath hold with the body's slightly longer length. To counter buoyancy, the bones have become slightly denser to add weight to the body.
Rostrovenator letaligibbas will commonly hunt schooling muscals such as Suboslontus communis and Communoslontus populator, although the young may also practice hunting smaller lone creatures such as Suboslontus whiskerius, Suboslontus devilosis, and Oslontus brycomi. Adults may also occasionally hunt Nataresukus bonii, but do not actively search for them.
They will opportunistically hunt smaller wyverns from the surface that are not paying attention, such as Aquadracius thalassomoloch, Aquadracius neofoundus, Aquadracius urioportus, Aquadracius tridactylus, and Pelecanimimus unculodon. Mothers will act highly aggressive towards anything that resembles Macrognathusensis dracokillus within one-hundred meters (100m) away in order to reduce competition for their offspring. They will dive under the eel, no deeper than thirty meters (30 m) underwater due to pressure constraints, and will swim upwards vertically at speeds of up to twenty miles per hour (20 mph) to stun the eel with its bony snout extension, breaking ribs and rupturing internal organs. The mother will then grab the unfortunate eel in her jaws and viciously shake it around, ripping it into pieces in the water which are fed on by the mother and her calf.
Rostrovenator letaligibbas will reproduce once a year and gives birth to one calf. Birth? This is not true birth like as in mammals, but rather the single egg will actually hatch in the womb before actually being laid. The newborn will then eat the eggshell around it for extra calcium. The mother will beach herself to give birth, in order to prevent the accidental drowning of the calf, but this allows the mother to be able to return to the waters much more quickly and this reduces the chances of any unfortunate event happening to the egg, further increasing survival rates of offspring. The mother will stick around with her calf for twenty-four (24) weeks until it molts from its newborn white coat into its adult black-and-white coat, which signals that the calf is mature enough to hunt and survive on its own while being large enough to avoid being hunted by other predators in the zone. The snout extensions only develop after maturity, and males will have bright orange skin while females have a silvery-colored skin after maturing for sexual dimorphism (to easily tell between the sexes).
