Monsters throughout the Monster Hunter Series are of a specific monster type. This type is defined by the monster's behaviour, appearance, habitat and in other cases, it's intelligence.
Lynians consist of Felyne, Melynx, Shakalaka and King Shakalaka. Lynians are usually described as "humanoid-like" beings of higher intelligence than that of an ordinary beast such as a Herbivore or Wyvern. Lynians such as Felynes and Melynxs are known to be capable of speech and coincide with hunters in villages, usually under the employment of human masters. Lynians such as the Shakalaka and King Shakalaka are more primitive however, dwelling in forested areas rather than urban areas, they settle in their own naturally developed villages. Felynes and Melynxes prefer to live in democratic societies, Shakalakas follow a ruler of their groups, known as the King Shakalaka, who is identified by a BBQ Spit on their head, a well-done steak as a weapon and a slightly larger mask.
Neopterons consist of Vespoid, Queen Vespoid, Hornetaur and Great Thunderbug. Neopterons are situated in large groups rather than individually. Most carry poisonous stingers that can paralyze prey, and their bodies are made up of acidic substances. Their weak outer-shell structures means that they are easily damaged, making it difficult to obtain adequate materials from their remains. However, this problems is overcome if the monsters are to die from poisonous causes, rather than attacks.
Herbivores consist of Anteka, Popo, Kelbi, Mosswine, Aptonoth and Apceros. Normally calm and docile, they only attack when angered or in self-defence. Being easily approachable, they are hunted for their meat rather than materials to supplement hunter needs. Other Herbivore commodities such as eggs are valuable.
 Bird Wyvern
Bird Wyverns consist of Giaprey, Giadrome, Velociprey, Velocidrome, Genprey, Gendrome, Ioprey, Iodrome, Yian Kut-Ku, Yian Garuga, Gypceros and Hypnocatrice. Bird Wyverns are monsters which closely resemble birds, having very similar appearances, bearing beaks, clawed feet or feathers and being relatively smaller and weaker to conventional wyverns such as the Rathalos. Their attacks also resemble that of birds, such as pecking, waddling and flapping of their wings. The "Prey" and "Drome" monsters are classed as bird wyverns due to their evolutionary advance from their primary stage as birds. This is similar to modern day findings of close relations between birds and dinosaurs, where fossils have proved that Birds have evolved over millions of years from dinosaurs.
Wyverns consist of Remobra, Rathian, Rathalos, Khezu, Basarios, Gravios, Monoblos, Diablos, Tigrex, Nargacuga and Espinas. Wyverns are distinguised by their large wings and ability to fly, as well as being rather large and highly aggresive. The will attack hunters and monsters alike. Wyverns also spend time in their nests rather than wandering around aimlessly like Bird Wyverns and as such are very territorial. They will retreat whenever injured however.
 Brute Wyvern
Brute Wyverns consist of Barroth, Uragaan, Deviljho, and more recently Brachydios (<-Monster hunter tri Ultimate). This species was first introduced in monster hunter tri. Brute Wyverns are highly aggressive, and are characterized by their above average attack and/or defense abilities. Their attacks are varied from each other, but they all possess a powerful charge attack to watch out for. Brute Wyverns can be found throughout the monster hunter world, living in some of the harshest of conditions. With the exception of Barroth all are 5 star difficulty or above for good reason.
Piscines consist of Cephalos, Cephadrome, Plesioth and Lavasioth. Piscines are seen constantly in their own territory and tend to keep within their suited habitat. This can range from water (Plesioth) to Land (sand for Cephalos and Cephadrome) and Lava (Volganos). Piscines are known for their commonly used attack called the "Hip-Thrust", which can be the bain of hunters.
Carapaceons consist of Hermitaur, Daimyo Hermitaur, Ceanataur, Shogun Ceanataur and the Shen Gao Ren. They are crap-like monsters with a hard exoskeleton and a soft gooey inside. They tend to hide underground, if not stand motionless in the open until they spot their prey. Their attacks have a wide range and usually knock the hunter down, which include spitting water and swiping their claws.
Pelagus (also known as Primatius) consist of Bullfango, Bulldrome, Conga, Congalala, Blango, Blangonga and Rajang. Their are mammal-like monsters which use their own body to attack hunters. This can range from head-butting to body slamming. Their generally have sharp claws and thick furred bodies. They cannot fly, but some can leap enourmous heights.
 Elder Dragon
Elder Dragons consist of Kirin, Kushala Daora, Chameleos, Lunastra, Teostra, Lao-Shan Lung, Fatalis, Yama Tsukami, Akantor and Ukanlos. Being called Elder Dragons, their lifespan lasts over hundreds of years. While being called dragons, not all necessarily have wings anc claws. Elder Dragons are known to be incredbily strong, rare and to retreat when in mortal danger.
Leviathans consist of Agnaktor, Gobul, Lagiacrus, Ludroth, Royal Ludroth and Uroktor . The Leviathan monster species first introduced in Monster Hunter 3, are identified by their similar appearance to crocodiles. They are also known to survive in underwater conditions, while others throughout magma in volcanoes.
