The climate became drier and drier, but the salamanders like it moist. As larvae, they lived in the water, where everything was still fine.

But deep in their genes, many caudates have stored the option of not going through metamorphosis completely and living in the water even as adults. The sexually mature animals then retain some larval characteristics, such as the external gills with which they can breathe under water. This phenomenon is called neoteny, and the best-known example of it worldwide is a close relative of Anderson\u2019s salamander: the axolotl. If staying in the water brings a survival advantage, evolutionary mechanisms ultimately ensure that at some point the whole population stays in the lake that was originally only their nursery for life.[\/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;0&#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;187686&#8243;][vc_column width=&#8221;1\/1&#8243;][vc_custom_heading uncode_shortcode_id=&#8221;956475&#8243;]Mole salamanders \u2013 doubly diverse[\/vc_custom_heading][\/vc_column][\/vc_row][vc_row row_height_percent=&#8221;&#8221; override_padding=&#8221;yes&#8221; h_padding=&#8221;&#8221; top_padding=&#8221;&#8221; bottom_padding=&#8221;&#8221; overlay_alpha=&#8221;&#8221; gutter_size=&#8221;&#8221; column_width_percent=&#8221;&#8221; shift_y=&#8221;&#8221; z_index=&#8221;&#8221; top_divider=&#8221;&#8221; bottom_divider=&#8221;&#8221; style=&#8221;inherited&#8221; uncode_shortcode_id=&#8221;133485&#8243; el_class=&#8221;gross_navigation_innen&#8221;][vc_column column_width_percent=&#8221;100&#8243; align_horizontal=&#8221;align_center&#8221; gutter_size=&#8221;2&#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; zoom_width=&#8221;0&#8243; zoom_height=&#8221;0&#8243; width=&#8221;1\/1&#8243; uncode_shortcode_id=&#8221;143018&#8243;][vc_gallery el_id=&#8221;gallery-12&#8243; type=&#8221;carousel&#8221; medias=&#8221;135522,135520,135518,135516,135514,135512,135510,135508,135506&#8243; carousel_lg=&#8221;1&#8243; carousel_md=&#8221;1&#8243; carousel_sm=&#8221;1&#8243; thumb_size=&#8221;sixteen-nine&#8221; gutter_size=&#8221;0&#8243; media_items=&#8221;media|nolink|original,description,caption&#8221; carousel_type=&#8221;fade&#8221; carousel_interval=&#8221;0&#8243; carousel_navspeed=&#8221;400&#8243; carousel_loop=&#8221;yes&#8221; carousel_nav=&#8221;yes&#8221; carousel_dots=&#8221;yes&#8221; carousel_dots_mobile=&#8221;yes&#8221; carousel_dots_inside=&#8221;yes&#8221; carousel_dot_padding=&#8221;5&#8243; stage_padding=&#8221;0&#8243; single_text=&#8221;under&#8221; single_overlay_opacity=&#8221;50&#8243; single_overlay_anim=&#8221;no&#8221; single_text_anim=&#8221;no&#8221; single_image_anim=&#8221;no&#8221; single_reduced=&#8221;three_quarter&#8221; single_padding=&#8221;2&#8243; single_title_semantic=&#8221;h4&#8243; single_meta_custom_typo=&#8221;yes&#8221; single_meta_weight=&#8221;500&#8243; single_icon=&#8221;fa fa-search3&#8243; single_border=&#8221;yes&#8221; lbox_caption=&#8221;yes&#8221; no_double_tap=&#8221;yes&#8221; carousel_rtl=&#8221;&#8221; single_title_uppercase=&#8221;&#8221; single_title_bold=&#8221;&#8221; single_title_serif=&#8221;&#8221; onclick=&#8221;link_image&#8221; custom_links_target=&#8221;_self&#8221; items=&#8221;eyI4ODY4X2kiOnsic2luZ2xlX3dpZHRoIjoiNCIsInNpbmdsZV9oZWlnaHQiOiI0In0sIjg4NjJfaSI6eyJzaW5nbGVfd2lkdGgiOiI0Iiwic2luZ2xlX2hlaWdodCI6IjQifSwiODg2MF9pIjp7InNpbmdsZV93aWR0aCI6IjQiLCJzaW5nbGVfaGVpZ2h0IjoiNCJ9LCIyNjIxOF9pIjp7InNpbmdsZV93aWR0aCI6IjQiLCJzaW5nbGVfaGVpZ2h0IjoiNCJ9LCIyNjIyNF9pIjp7InNpbmdsZV93aWR0aCI6IjQiLCJzaW5nbGVfaGVpZ2h0IjoiNCJ9LCIyNjIyMl9pIjp7InNpbmdsZV93aWR0aCI6IjQiLCJzaW5nbGVfaGVpZ2h0IjoiNCJ9LCIyNjIyOV9pIjp7InNpbmdsZV93aWR0aCI6IjQiLCJzaW5nbGVfaGVpZ2h0IjoiNCJ9fQ==&#8221; single_half_padding=&#8221;&#8221; single_no_background=&#8221;&#8221; uncode_shortcode_id=&#8221;171898&#8243;][\/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;3&#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;860223&#8243;][vc_column width=&#8221;1\/1&#8243;][vc_custom_heading uncode_shortcode_id=&#8221;788135&#8243;]Islands under water[\/vc_custom_heading][vc_column_text uncode_shortcode_id=&#8221;157166&#8243;]So the land-dwelling mole salamanders in the highlands of Mexico gradually became water-dwelling mole salamanders, swimming around in the various lakes of the region with their inflows and outflows. And promptly evolution struck again, this time with the famous island effect. Since the different lakes are spatially separated from each other and therefore the salamanders living in them no longer had any contact with each other, they developed their own characteristics over millions of years, through random mutations or special adaptations to their environment. At some point, they had taken such different paths that they had become species of their own \u2013 a prime example of the emergence of biodiversity.[\/vc_column_text][\/vc_column][\/vc_row][vc_row unlock_row=&#8221;&#8221; row_height_percent=&#8221;60&#8243; override_padding=&#8221;yes&#8221; h_padding=&#8221;2&#8243; top_padding=&#8221;2&#8243; bottom_padding=&#8221;0&#8243; back_color=&#8221;color-xsdn&#8221; back_image=&#8221;135526&#8243; back_attachment=&#8221;scroll&#8221; parallax=&#8221;yes&#8221; overlay_color=&#8221;color-jevc&#8221; overlay_alpha=&#8221;0&#8243; equal_height=&#8221;yes&#8221; gutter_size=&#8221;3&#8243; column_width_percent=&#8221;100&#8243; shift_y=&#8221;0&#8243; z_index=&#8221;0&#8243; top_divider=&#8221;gradient&#8221; bottom_divider=&#8221;gradient&#8221; uncode_shortcode_id=&#8221;654089&#8243; back_color_type=&#8221;uncode-palette&#8221; overlay_color_type=&#8221;uncode-palette&#8221;][vc_column column_width_percent=&#8221;70&#8243; position_vertical=&#8221;middle&#8221; gutter_size=&#8221;3&#8243; style=&#8221;dark&#8221; overlay_alpha=&#8221;50&#8243; radius=&#8221;sm&#8221; 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\/1&#8243; uncode_shortcode_id=&#8221;147564&#8243;][vc_custom_heading css_animation=&#8221;bottom-t-top&#8221; animation_delay=&#8221;300&#8243; uncode_shortcode_id=&#8221;360231&#8243;]Anderson&#8217;s Salamander lives exclusively in the Laguna de Zacapu, a small lake with an area of less than 40 hectares.[\/vc_custom_heading][vc_empty_space empty_h=&#8221;2&#8243;][\/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;0&#8243; bottom_padding=&#8221;2&#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;234961&#8243;][vc_column width=&#8221;1\/1&#8243;][vc_column_text text_lead=&#8221;small&#8221; uncode_shortcode_id=&#8221;658022&#8243;]Laguna de Zacapu \u00a9 Joachim Nerz[\/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;2&#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;207423&#8243;][vc_column width=&#8221;1\/1&#8243;][vc_custom_heading uncode_shortcode_id=&#8221;115302&#8243;]The salamander goes for the gills[\/vc_custom_heading][vc_column_text uncode_shortcode_id=&#8221;528708&#8243;]Anderson\u2019s Salamader lives exclusively in the Laguna de Zacapu, a small lake with an area of less than 40 hectares. A well-isolated, tiny habitat and at the same time a laboratory of speciation. In addition to Anderson\u2019s salamader, there are several species of fish and crayfish found only there. However, the lake is located directly next to the 50,000-inhabitant city of Zacapu, it is its city pond, so to speak. Agriculture is practised in the surrounding area. Both of these factors lead to considerable water pollution and siltation, which severely affects the salamanders. In addition, the quite handsome animals (28 cm long) have always been considered a delicacy, which is why they were fished and probably still are, despite being protected. The animals cannot escape \u2013 the World Conservation Union IUCN therefore rates them in the highest threat category for wild species as acutely \u201cthreatened with extinction\u201d.[\/vc_column_text][\/vc_column][\/vc_row][vc_row row_height_percent=&#8221;0&#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;170136&#8243;][vc_column column_width_percent=&#8221;100&#8243; gutter_size=&#8221;2&#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\/1&#8243; uncode_shortcode_id=&#8221;211499&#8243;][vc_single_image media=&#8221;133493&#8243; media_width_percent=&#8221;100&#8243; uncode_shortcode_id=&#8221;202038&#8243;][vc_column_text text_lead=&#8221;small&#8221; uncode_shortcode_id=&#8221;313593&#8243;]The Circle of Life: &#8220;Normal&#8221; salamander development proceeds from eggs in which larvae develop, hatch mostly legless, then develop limbs, grow up and finally undergo metamorphosis. The metamorphosed animals then live on land until they themselves proceed to reproduce. Neotenous salamanders take a shortcut in the water: they go through metamorphosis only partially, remain in the water and are still sexually mature as &#8220;permanent larvae&#8221;. \u00a9 Jonas Lieberknecht[\/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;2&#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;128877&#8243;][vc_column width=&#8221;1\/1&#8243;][vc_custom_heading uncode_shortcode_id=&#8221;936114&#8243;]Create two, three, many lakes[\/vc_custom_heading][vc_column_text uncode_shortcode_id=&#8221;114167&#8243;]Basically, such a small lake is also just a big aquarium. Unfortunately, it is currently defective, and repairing it is possible in principle, but requires a lot of time, money and effort. So far, work on this has not even begun in earnest. It is therefore likely that on-site rescue efforts will come too late for Anderson\u2019s Salamander. He may soon become extinct in the Laguna de Zacapu. This is why Citizen Conservation wants to help provide the animals with other, functioning aquariums \u2013 in zoos and with private amphibian friends. After all, keeping and breeding these amphibians is quite possible, and Anderson\u2019s Salamander is quite frugal in itself. If enough people join in, we can offer him asylum in human care until one day, hopefully, his native lake will be made amphibian-friendly again. And it would be a shame if these gems of evolution were no longer to exist.
