Cladistics
Cladistics, founded by Willi Hennig, is a systematics method grouping organisms into clades by shared derived characters (synapomorphies) rather than overall similarity, using parsimony and cladograms, distinct from phenetics and evolutionary taxonomy.
Cladistics (journal)
Cladistics is a peer-reviewed systematics journal published by Wiley for the Willi Hennig Society since 1985 (ISSN 0748-3007), edited by Rudolf Meier, requiring parsimony analyses, with Q1 SCImago ranking and six issues yearly.
Cladocora caespitosa
Cladocora caespitosa (Linnaeus, 1767), the Mediterranean pillow or cushion coral, is the sea's only zooxanthellate reef-building coral, endemic to the Mediterranean, IUCN Endangered since 2015, threatened by marine heatwaves above 24 °C.
Cladogram
Cladogram: branching diagram of hypothesized relationships among taxa, central to Hennig's cladistics (Phylogenetic Systematics, 1966). Built from synapomorphies via parsimony; distinct from phenograms and phylograms.
Cladonia (genus)
Cladonia is a genus of lichenized ascomycete fungi in the family Cladoniaceae, its largest genus with about 475 species, recognized by hollow podetia and found from the Arctic to Antarctica.
Cladonia arbuscula

Cladonia rangiferina
Cladonia rangiferina (reindeer lichen, reindeer moss, formerly Cladina rangiferina) is a grey, tetrachotomously branched fruticose lichen of northern heaths and tundra, K+ yellow from atranorin, a key reindeer winter forage, distinct from C. arbuscula and C. stygia.
Cladonia stellaris
Cladonia stellaris, also known as star-tipped reindeer lichen or Cladina stellaris, is a pale, mat-forming lichen dominant in arctic and boreal regions of the northern hemisphere and a principal winter forage of reindeer and caribou.
Cladoniaceae
Cladoniaceae is a family of lichen-forming fungi in the order Lecanorales, with about 530 species in 17 genera, dominated by Cladonia, whose members form upright podetia and include the reindeer lichens.

Clam
Clam: common name for edible burrowing bivalve mollusks such as the soft-shelled steamer and hard-shelled quahog; filter-feeding, hinged two-valve shell, Cambrian origin, major fisheries and aquaculture species worldwide.
