between a few lays and 2 weeks. When adults, Spiny Waterfleas reproduce both sexually and asexually. During the summer, they reproduce using parthenogenesis which is a type of asexual reproduction, and produce up to 10 (eggs) identical copies of the mother. On the other hand, when the water conditions are cool, they reproduce sexually, by producing tougher eggs that are resistant to freezing, drying, and breaking before it is time. The females carry the eggs on their back. When Spiny Waterfleas reproduce asexually, only one parent is required, while for sexual reproduction, two parents are required.

Asia. This organism is found in open waters, including the

as well as a black eyespot. Another characteristic of this

organism is the 4 pairs of legs, with the first pair

being longer than the others, to make catching prey

easier, and a pair of swimming antennae , to make swimming

faster. The Bythotrephes Longimanus is a multicellular

organism, made up of eukaryotic cells, which means

that its DNA is located in the nucleus of each

cell.
