KMC is a tool for k-mer counting that uses a multidisk architecture for optimized speed [69] Gerbil uses a hash table approach but with added support for GPU acceleration [70] K-mer Analysis Toolkit (KAT) uses a modified version of Jellyfish to analyze k-mer counts [6]
Skmer uses a 2 stage approach to compute these distances. First, it generates k-mer frequency profiling using a tool called JellyFish [34] and then these k-mers are converted into hashes. [33] A random subset of these hashes are selected to form a so-called "sketch". [33]
Pelagia noctiluca is a jellyfish in the family Pelagiidae and the only currently recognized species in the genus Pelagia. [1] It is typically known in English as the mauve stinger, [3] [4] but other common names are purple-striped jelly (causing potential confusion with Chrysaora colorata), [5] purple stinger, purple people eater, [6] purple jellyfish, luminous jellyfish and night-light ...
The medusae of most species are fast-growing, and mature within a few months then die soon after breeding, but the polyp stage, attached to the seabed, may be much more long-lived. Jellyfish have been in existence for at least 500 million years, [1] and possibly 700 million years or more, making them the oldest multi-organ animal group. [2]
Staurozoa is a class of Medusozoa (or jellyfish).It has one extant order: Stauromedusae (stalked jellyfishes) with a total of 50 known species. A fossil group called Conulariida has been proposed as a second order, [3] although this is highly speculative.
Aurelia aurita (also called the common jellyfish, moon jellyfish, moon jelly or saucer jelly) is a species of the family Ulmaridae. [1] [2] All species in the genus are very similar, and it is difficult to identify Aurelia medusae without genetic sampling; [3] most of what follows applies equally to all species of the genus.

The Scyphozoa are an exclusively marine class of the phylum Cnidaria, [2] referred to as the true jellyfish (or "true jellies"). The class name Scyphozoa comes from the Greek word skyphos (σκύφος), denoting a kind of drinking cup and alluding to the cup shape of the organism. [3] Scyphozoans have existed from the earliest Cambrian to the ...
