In 1930, a black newt with rather warty skin and conspicuous, longitudinally running ridges of protruding lumps on the middle and sides of the back was scientifically described under the name <em>Tylototriton asperrimus<\/em>. With the German name \u201cStacheliger Krokodilmolch\u201d, translating to Spiny crocodile newt, its appearance is quite well illustrated. Its range extends over the subtropical evergreen forests in large parts of central and southern China and northern Vietnam \u2013 or so it was thought.[\/vc_column_text][\/vc_column][\/vc_row][vc_row row_height_percent=&#8221;0&#8243; override_padding=&#8221;yes&#8221; h_padding=&#8221;2&#8243; top_padding=&#8221;2&#8243; bottom_padding=&#8221;1&#8243; overlay_alpha=&#8221;50&#8243; gutter_size=&#8221;3&#8243; column_width_percent=&#8221;100&#8243; shift_y=&#8221;0&#8243; z_index=&#8221;0&#8243; uncode_shortcode_id=&#8221;124021&#8243;][vc_column width=&#8221;1\/1&#8243;][vc_custom_heading text_size=&#8221;h3&#8243; uncode_shortcode_id=&#8221;404683&#8243;]Crocodile newts[\/vc_custom_heading][\/vc_column][\/vc_row][vc_row row_height_percent=&#8221;0&#8243; override_padding=&#8221;yes&#8221; h_padding=&#8221;1&#8243; top_padding=&#8221;1&#8243; bottom_padding=&#8221;2&#8243; overlay_alpha=&#8221;100&#8243; gutter_size=&#8221;100&#8243; column_width_percent=&#8221;100&#8243; shift_y=&#8221;0&#8243; z_index=&#8221;0&#8243; style=&#8221;inherited&#8221; uncode_shortcode_id=&#8221;133907&#8243; front_end_with_slider=&#8221;true&#8221;][vc_column column_width_percent=&#8221;100&#8243; align_horizontal=&#8221;align_center&#8221; gutter_size=&#8221;3&#8243; style=&#8221;light&#8221; overlay_alpha=&#8221;50&#8243; shift_x=&#8221;0&#8243; shift_y=&#8221;0&#8243; z_index=&#8221;0&#8243; medium_width=&#8221;0&#8243; zoom_width=&#8221;0&#8243; zoom_height=&#8221;0&#8243; width=&#8221;1\/1&#8243;][uncode_slider slider_interval=&#8221;0&#8243; slider_navspeed=&#8221;200&#8243; slider_loop=&#8221;yes&#8221;][vc_row_inner row_inner_height_percent=&#8221;0&#8243; overlay_color=&#8221;color-xsdn&#8221; overlay_alpha=&#8221;50&#8243; gutter_size=&#8221;4&#8243; shift_y=&#8221;0&#8243; z_index=&#8221;0&#8243; limit_content=&#8221;yes&#8221; front_end_with_slider=&#8221;true&#8221; uncode_shortcode_id=&#8221;144687&#8243; overlay_color_type=&#8221;uncode-palette&#8221;][vc_column_inner width=&#8221;2\/3&#8243;][vc_single_image media=&#8221;133498&#8243; caption=&#8221;yes&#8221; media_width_percent=&#8221;100&#8243; uncode_shortcode_id=&#8221;797642&#8243;][\/vc_column_inner][vc_column_inner column_width_percent=&#8221;100&#8243; position_vertical=&#8221;middle&#8221; gutter_size=&#8221;3&#8243; overlay_alpha=&#8221;50&#8243; shift_x=&#8221;0&#8243; shift_y=&#8221;0&#8243; shift_y_down=&#8221;0&#8243; z_index=&#8221;0&#8243; medium_width=&#8221;0&#8243; mobile_width=&#8221;0&#8243; width=&#8221;1\/3&#8243; uncode_shortcode_id=&#8221;110120&#8243;][vc_custom_heading heading_semantic=&#8221;h4&#8243; text_size=&#8221;h4&#8243; sub_lead=&#8221;yes&#8221; uncode_shortcode_id=&#8221;156986&#8243;]Ziegler&#8217;s crocodile newt was not recognized as a distinct species until 2013.[\/vc_custom_heading][\/vc_column_inner][\/vc_row_inner][vc_row_inner row_inner_height_percent=&#8221;0&#8243; overlay_color=&#8221;color-xsdn&#8221; overlay_alpha=&#8221;50&#8243; gutter_size=&#8221;4&#8243; shift_y=&#8221;0&#8243; z_index=&#8221;0&#8243; limit_content=&#8221;yes&#8221; front_end_with_slider=&#8221;true&#8221; uncode_shortcode_id=&#8221;132541&#8243; overlay_color_type=&#8221;uncode-palette&#8221;][vc_column_inner width=&#8221;2\/3&#8243;][vc_single_image media=&#8221;133499&#8243; caption=&#8221;yes&#8221; media_width_percent=&#8221;100&#8243; uncode_shortcode_id=&#8221;928804&#8243;][\/vc_column_inner][vc_column_inner column_width_percent=&#8221;100&#8243; position_vertical=&#8221;middle&#8221; gutter_size=&#8221;3&#8243; overlay_alpha=&#8221;50&#8243; shift_x=&#8221;0&#8243; shift_y=&#8221;0&#8243; shift_y_down=&#8221;0&#8243; z_index=&#8221;0&#8243; medium_width=&#8221;0&#8243; mobile_width=&#8221;0&#8243; width=&#8221;1\/3&#8243; uncode_shortcode_id=&#8221;261155&#8243;][vc_custom_heading heading_semantic=&#8221;h4&#8243; text_size=&#8221;h4&#8243; sub_lead=&#8221;yes&#8221; uncode_shortcode_id=&#8221;614637&#8243;]This photo shows the specimen kept in a natural history museum that was used to describe the &#8220;original&#8221; Spiny Crocodile Newt (<em>Tylototriton asperrimus<\/em>).
