A fish is any member of a paraphyletic group of organisms that consist of all gill-bearing aquatic craniate animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish, as well as various extinct related groups. Most fish are ectothermic ("cold-blooded"), allowing their body temperatures to vary as ambient temperatures change, though some of the large active swimmers like white shark and tuna can hold a higher core temperature. Fish are abundant in most bodies of water. They can be found in nearly all aquatic environments, from high mountain streams (e.g., char and gudgeon) to the abyssal and even hadal depths of the deepest oceans (e.g., gulpers and anglerfish). At 32,000 species, fish exhibit greater species diversity than any other group of vertebrates.

Rubus laciniatus, commonly called evergreen blackberry or cutleaf blackberry, is a species of blackberry that is native to Eurasia. It has been introduced to Australia and North America, and become a weed and highly invasive species in forested habitats in the United States and Canada, it is very difficult to control. Evergreen blackberry is a deciduous shrub that grows up to 3 meters tall with prickly shoots. The flowers are in clusters, the petals are pink or white. The fruits are shiny and black, similar to the common blackberry, with a unique and fruitier taste. The fruits are not true berries in the botanical sense. [Wikipedia]
