Explanation:

 'Hominoid' (or 'Hominoid') is the taxonomic designation for the group of organisms commonly known as apes. In modern taxonomy, this group falls on the level of a super family (of the parvorder Catarrhini, of the suborder Haplorrhini, of the order Primates). Members of the Hominoidea super family share some common traits, such as (1) 5 cusps on their molar teeth called the Y-5 pattern; (2) more mobile shoulder joints and arms; (3) broad ribcages that are flatter front-to-back; (4) shorter and less mobile spine. All extant members of Hominoidea are tailless.
'Hominid' (or 'Hominidae') is the taxonomic designation for the group of organisms commonly known as great apes. Taxonomically, it falls on the level of a family and, as such, is a subset of the Hominoidea superfamily. The average size of even the smallest members of the great apes dwarfs the largest lesser ape (these being all the members of the Hominoidea superfamily not in the Hominidae family, i.e., the Hylobatidae or gibbon family). The only extant species of the great apes today are (1) the orangutan; (2) the gorilla; (3) the chimpanzee; (4) the human.
