    When querying the taxonomies with a specific post type like “posts” in this case, only the taxonomies connected only with this post type will be shown. If a taxonomy is attached to multiple post types it will not be listed. Core Trac Ticket 27918

    <?php 
    $args = array(
    	'name' => array(
    		'post',
    	),
    );
    $taxonomies = get_taxonomies( $args );

    The alternative is to use get_object_taxonomies().

    Display a list of only public custom taxonomies — will not list include WordPress built-in taxonomies (e.g., categories and tags):

    <?php 
    $args = array(
      'public'   => true,
      '_builtin' => false
      
    ); 
    $output = 'names'; // or objects
    $operator = 'and'; // 'and' or 'or'
    $taxonomies = get_taxonomies( $args, $output, $operator ); 
    if ( $taxonomies ) {
    	echo '<ul>';
    	foreach ( $taxonomies  as $taxonomy ) {

    Display the plural name of a specific taxonomy (and setting the output to be 'object' rather than the default 'array‘):

    <?php 
    $args = array(
    	'name' => 'genre'
    );
    $output = 'objects'; // or names
    $taxonomies= get_taxonomies( $args, $output ); 
    if ( $taxonomies ) {
    	foreach ( $taxonomies as $taxonomy ) {
    		echo '<div>' . $taxonomy->labels->name . '</div>';
    	}
    }  
    ?>

    This can be used in certain use cases as if you need to find the taxonomy from a term slug

                    // We want to find the Taxonomy to this slug.
                    $term_slug = 'myterm';
                    $taxonomies = get_taxonomies();
                    foreach ( $taxonomies as $tax_type_key => $taxonomy ) {
                        // If term object is returned, break out of loop. (Returns false if there's no object)
                        if ( $term_object = get_term_by( 'slug', $term_slug , $taxonomy ) ) {
                            break;
                        }
                    }
    				//Get the taxonomy!!
                    echo $term_object->taxonomy . '<br>';
    
    				// You can also retrieve other thing of the term:
                    echo $term_object->name . '<br>'; //term name
                    echo $term_object->term_id . '<br>'; // term id
                    echo $term_object->description . '<br>'; // term description
    
    				// See all options by dumping the $term_object:
    				//var_dump( $term_object );
