Black Sea Hare Facts
- Impressively, the truly stunning Black Sea Hare represents an extremely large species of animal known as a sea slug. For the moment, a total of roughly 3,000 recognized varieties of such creatures exist. That’s an astounding number.
- This creature forms the largest all of presently known related species. Yet, its superior size alone does not constitute its only difference from related creatures. Nature, it would seem, chose to set it apart from its brethren in more ways than one.
- This holds true, in part, because unlike most of its brethren, this remarkable sea slug actually does not produce ink. In addition to this, its evolved defensive measures, which are quite impressive, also set it apart from similar creatures.
- Since it lacks ink, the invertebrate protects itself from predators by making its flesh undesirable to them. While other species also do this, it approaches it from an unusual angle. This occurs due to the fact that its principle food source contains natural toxins.
- The magnificent Black Sea Hare, however, evolved a natural immunity to such poisons. As a result of its consumption of the animals, the toxin builds up concentrations in its flesh sufficient to make it lethal to potential predators.
Black Sea Hare Physical Description
Most notably, the fabulous variety of sea slug known as the Black Sea Hare remains a truly impressive physical specimen of its kind. That’s true because of the fact that this stunning creature ranks as a true giant, at least compared to species sharing its Order.
The trait of sexual dimorphism plays no noticeable natural role for this invertebrate, however. That holds true because it evolved as a simultaneous hermaphrodite. Due to this, each individual remains both male and female throughout its life.
To begin with, mature individuals of this particular species attain an average size of about 15 in (38 cm) in length. Exceptional specimens do occasionally occur, though. Some individuals, therefore, reach total lengths of as much as 39 in (99 cm).
This natural wonder also grows to a relatively astounding weight for its kind. This remains true because an average weight for this slug equals roughly 15 lb (6.8 kg). Yet those same exceptional specimens sometimes reach a weight of as much as 31 lb (14 kg).
The relatively enormous body of the Black Sea Hare further generally presents a dark black in coloring. Yet, occasionally different shades sometimes appear. And lastly, the body itself remains comparatively firm in relation to similar animals.

Black Sea Hare Distribution, Habitat, and Ecology
Most unfortunately for lovers of Nature, the incredible Black Sea Hare has a restricted habitat range. In point of fact, it only inhabits the coastal waters of two areas. These consist of the coast of California, in the United States, and Baja California, Mexico.
Mike others of its kind, this truly remarkable animal also has an entirely herbivorous diet. In its case, however, the creature has also evolved a highly specific one. In fact, it only feeds on kelp and brown seaweed, being immune to its toxins.
This fabulous and quite surprising animal also typically grows quite rapidly. That at least holds true in relation to its relatives. In point of fact, an average weight gain per day among individuals monitored equaled nearly an astonishing 5 grams per day.
Finally, being hermaphroditic in nature also gives the Black Sea Hare a decided edge over competing species. Due to this remarkable evolutionary trait, any two individuals can reproduce together. But sadly, its average lifespan on equals roughly one year.
