2. 
 Animals having one set of teeth of which none are
replaced at a later stage of growth
 Examples:
 Beluga whale
 Aquatic mammals (Cetacea) include a group of
toothed whales(Odontoceti) that are mostly homodont
and monophyodont

4. 
 Any animal with two successive sets of teeth,
initially the "deciduous" set and consecutively the
"permanent" set.
 Most mammals are diphyodonts as to chew their
food they need a strong, durable and complete set of
teeth.
 Examples:
 Human
 Most mammals are diphyodont, except kangaroos,
elephants and manatees.

 Animals having several or many sets of teeth in
succession
 Examples:
 Polyphyodonts include most toothed fishes, many
reptiles such as crocodiles and geckos

 Teeth that are all of similar form
 Homo means same, dont means dentition
 Homodont refers to same set of teeth
 Examples:

 Dolphins

 Conodonts (kōnos, "cone", + odont, "tooth") are
extinct agnathan chordates resembling eels, classified
in the class Conodonta.
 For many years, they were known only from tooth-
like microfossils found in isolation and now
called conodont elements.
 Their teeth are called codont.
 They are pointed cone shaped
