Pelagic
Migratory, ocean-crossing. Live within the open-ocean.
One of the most common subtypes of ray dog, with huge amounts of variation. Some pelagic rays are huge in size, resembling whale sharks and other filterfeeders, whilst others are much smaller and prefer shoaling behaviours. The majority of pelagic ray dogs are counter shaded, meaning their underside is a light colour and their topside a darker colour. Other markings are common, as is silvering and relflective coats.
Reef
Bright and zippy, much like the shallow waters and reefs they reside in.
Another common subtype. Reef myliolupus are small, nimble and come in a huge variety of colours. Typically residing in tropical waters, but they do also inhabit cold and temperate reefs. Their bright colouration helps to confuse and dissuade larger predators, and when that doesn't work, many feature sharp spines and spurs. Reef myliolupus have a hugely varied diet, some eating exclusively other fish, whilst others graze on the algae and corals.
Intertidal
Life is a beach day.
Intertidal myliolupus have thicker skin and fur to protect them from the general wear-and-tear of land-based life and strong, tidal waters. Their mouths are a little more dog-like and sit closer to the front of the face rather than underneath to aid them in breathing oxygen. With strong jaws, intertidal rays often feast on shellfish or seaweed. Similarly to their reef cousins, they can often be quite spiny and come in a variety of bright colours, though tend to have colourful accents rather than be full-on colour bomb. Their wings and fins are also smaller, which allows them to maker tighter turns but results in them struggling in deeper water with large currents.
Hadal
Residing within the deepest zones of the ocean.
Hadal Myliolupus are scarce and rarely seen, blending in perfectly with the inky black of the deep sea. Experiencing deep-sea gigantism, hadal rays are often among the largest of stingray dogs as a large body mass helps with the low temperatures and overall efficency. They are most often ambush and opportunistic feeders and have slow metabolisms to survive in such a harsh environment. Ranging from white, to dark reds and blacks, camouflage is very important. Many hadal rays also have bioluminesence to either distract or attract predators. Due to the relative stability of the deep sea, far below the rough tides far above, these myliolupus have soft bodies and are relatively sensitive creatures, they also tend to have less fur than their coastal and epipelagic counterparts.
Fresh Water
In a river near you!
Fresh water myliolupus are relatively rare, but often move into towns and cities due to their proximity to humans. Exhibiting more similarities to dogs than marine animals, they very frequently display domisticated markings such as piebalding and spots. Their wings are smaller in size though typically instead they have larger tail fins to aid their swimming in strong, fast flowing river water. Due to their proximity to humans, they are more commonly affected by pollution and are tragically more likely to suffer from mutations and deformities.
Terrestial
What
Huh?? But it's a stingray dog! How is it terrestial? The most commonly domesticated out of the lot, terrestial myliolupus are common-place pets and are well adapted to life on land. There are two further subspecies of terrestial myliolupus, being myliolupus familiaris and myliolupus ferus. As you may have guessed, the former are the domesticated type, which frequently have long, decorative fins and tails and come in an assortment of bright colours. These are not particularly practical in the wild, but as they live within the homes of people they don't really need to be. Domesticated stingray dogs certainly are stunning, and are incredibly friendly too, having unparalelled confidence in comparison to their wild cousins.
As for myliolupus ferus, they reside within many parts of the globe. Still depedent on water, they've not quite conquered all terrains but can be found anywhere which has enough water or high humidity. They have smaller wings, shorter tails and often much thicker fur which extends over their wings and tail. Terrestial myliolupus do have large teeth and strong jaws, they can absolutely bite. Their life on land has lead to several other adaptations and all terrestial myliolupus have an extra toe and may have both sets of dew claws.
