Sea
 angels
 have
 been
 parts
 of
 arctic
 ecosystem
 since
 the
 beginning
 of
 Ice
 

age.
 The
 8irst
 sea
 angels’
 ancestor
 lived
 during
 Palaeozoic
 era.
 This
 era
 began
 
approximately
 540
 million
 years
 ago,
 before
 the
 domination
 of
 dinosaurs
 in
 
Cretaceous
 period,
 and
 lasted
 about
 290
 million
 years.
 Palaeozoic
 era
 is
 where
 
marine
 creatures
 governed
 the
 earth.
 It
 also
 classi8ied
 in
 to
 six
 chronological
 
period,
 which
 are
 Cambrian,
 Ordovician,
 Silurian,
 Devonian,
 Carboniferous,
 and
 
lastly
 Permian
 (“Table
 of
 Geological
 Periods,”
 n.d.).
 My
 hypothesis
 is
 sea
 angels’
 
ancestor
 8irst
 appeared
 in
 Cambrian
 period
 because
 at
 that
 time
 it
 was
 the
 
proliferation
 of
 invertebrate
 sea
 life.
 In
 the
 following
 paragraphs,
 there
 will
 be
 
details
 of
 sea
 angels
 in
 depth
 about
 their
 taxonomy,
 foods,
 appearance,
 
classi8ication,
 etc.
 Also,
 in
 recent
 years,
 numerous
 of
 human
 action
 decrease
 
number
 of
 marine
 lives
 drastically,
 including
 sea
 angels
 and
 other
 arctic
 
creatures,
 will
 also
 be
 discussed.

Sea
 angels
 is
 considered
 to
 be
 in
 cellular
 life
 because
 it
 has
 cells
 and
 have
 

all
 7
 characteristic
 that
 life
 must
 have
 which
 is
 homeostasis,
 metabolism,
 
organisation,
 growth,
 adaptation,
 respond
 to
 stimuli,
 and
 reproduction
