Terracetus gigas

Wandering Hogbeasts(Terracetus gigas), also known as Land Whales, are creatures that inhabit humid woodlands. Their names are a reference to their head shape, which resembles that of a Bowhead Whale, and also their foraging habits, which resemble pigs.

Their most striking feature is certainly the bulky, powerful beak. It's so large and curved that it never fully closes, though its edges are rather blunt and thick. Two large bony protrusions line the edges of the lower beak, while four fairy tufts cover the upper beak's snout. These tufts are actually sensory organs that can extend into long tendrils, very similar to a tiger moth's Coremata. The whole face is covered in thin, stiff hairs that are very sensitive as well, they even aid in catching and guiding scent particles towards the olfactory orifices lining the lower jaw.

Hogbeasts use their large beaks as bulldozer blades: digging and pushing it into the soil to turn up sediment and expose any tasty underground creatures, possibly roots and tubers too(if this planet has anything similar to those). After they raise their head with a mouthful of dirt, four modified proboscides covered in fine sensory hairs proceed to feel around and sort through the sediment, pushing the dirt out of the permanently gaping mouth in the process. They are sensitive enough to easily detect movement and different textures. Once they've touched a burrowed creature, they will immediately grab it with their finger-like protrusions and drag it towards the inner beak. The proboscides are incredibly fast and efficient organs both in dry dirt and wet mud. They are able to comb through the sediment with a greater dexterity than human hands, while also grabbing food with the speed of a whip.
The inner beak is another modified proboscis, the only one that still kept its ancestral function of transporting food to the animal's stomach. By keeping it closed while combing through sediment, the hogbeast prevents dirt from being swallowed down accidentally. The proboscis is retractable and can be stretched out to directly regurgitate food into a hogbeast cub's mouth.
After food is swallowed through the inner beak proboscis, it will be crushed and sliced by a pair of radulas, which are bony plates covered in large, sharp teeth-like spines. The radulas will then push the broken down food further into the esophagus, which is lined with fleshy protrusions. These aid in moving food along the digestive tract until it finally reaches the stomach.
Besides foraging through the dirt, hogbeasts may complement their diet with sap from bone trees. Their powerful beak allows them to crack the hard, calcified shell so they may access the sweet sap/fluids inside. They feed by extending their inner beak and sipping directly from the cracked shell.
If their habitat is in close proximity to a beach, hogbeasts may also visit it in search of easy meals, like beached creatures and shelled animals hiding in the sand. They aren’t well adapted to combing sand, and thus aren’t as effective. Still, the beach offers lots of opportunities for easy food and they don't mind exploring such alternatives.

A hogbeast’s body is composed of 8 limbs, two of which were modified into fin-like structures that are covered in thick layers of fur. Near the connecting point of said limbs to the torso, there are two large vents leading to the respiratory system. The fine hairs surrounding it aid in blocking dust and dirt particles in the air as the hogbeast breathes. The inside of the respiratory canals is covered in hairs as well. The hairy flaps move in similar ways to mammalian ears, and they are often used for display as well(the skin and hairs on that limb are very colorful), whether it’s for attracting partners or intimidating potential threats.
While the body is covered in stiff fur(similar to a pig’s), the legs are hairless with a very thick, scaly skin. The scales are mostly small and blend in with the wrinkly skin, giving it a texture resembling an elephant’s hide. However, these scales also form large keratinous plates on the joints and feet. In the picture above I tried to highlight the different textures, varying from fur covered areas to the scale plated leg joints.
Tucked against the creature’s chest, there are two smaller arms with dexterous, four fingered hands. They are used for manipulating objects and digging, which allows hogbeasts to move obstacles away and get easier access to food and other points of interest. It also helps during mating season, when mated pairs work on building a nest for their young.
The other legs are large and bulky, with very soft pads on the soles of the feet. These pads are very sensitive and can detect movement from creatures hidden underground, which is how hogbeasts are able to spot good feeding grounds before digging away. The front legs also have a long spur for self defense, which the hogbeast occasionally will sharpen on the edges of its beak.
When it comes to social behavior, hogbeasts are very social, intelligent creatures, and interact with each other via their facial sensory tendrils. Such interactions involve caressing each other’s faces and body parts, nuzzling, playing with objects, mud bathing, etc. They move in herds of 3-10 individuals, though males and females walk in separate herds. They only meet during mating season, and, with the species practicing monogamy, the same pairs will keep reuniting every year. After mating, male and female will work together to build a nest using mud, dirt, rocks and other resources found in the woods. The male will be very protective of his mate, staying by her side as she lays 2-3 eggs in the nest, and then he will keep helping until their offspring is around 3 weeks old. At that point the pair will separate, with the male herd moving away and leaving the females to care for the cubs.
The hogbeast cubs will stay in the female herd until they become juveniles/adolescents. The males will be kicked away by the herd and will look for a bachelor herd, while females may choose to stay or leave. Usually they prefer to leave if the herd feels too overcrowded.
