Living Brachiopod, Further investigation . Study of the shells of living articulates confirms that endopunctae accommodate the Brachiopods are the most abundant fossils in Wisconsin. Nov 10, 2025 · Today, the Brachiopoda phylum is represented by only about 400 living species, a small fraction of the estimated 12,000 species known from the fossil record. Feeding: a living brachiopod A large part of the space between the two valves is occupied by a fleshy, hollow organ (the lophophore), which has long twisted or coiled arms and filaments. Living brachiopods exhibit relatively low diversity compared to their fossil record, with approximately 400-450 valid species currently recognized across more than 120 genera. The following is a taxonomy of extant (living) Brachiopoda by Emig, Bitner & Álvarez (2019). … Aug 1, 2023 · Interhemispheric biodiversity peaks of living brachiopods coinciding with warm-temperate zones and correlated to a multitude of biotic, abiotic and evolutionary factors Nov 8, 2021 · The global distribution patterns of 14918 geo-referenced occurrences from 394 living brachiopod species were mapped in 5° grid cells, which enabled the visualization and delineation of distinct bioregions and biodiversity hotspots. Cilia (hair-like organs) attached to the filaments beat rapidly, drawing in food-bearing water currents. The larvae of articulate species settle in quickly and form dense populations in well-defined areas while the larvae of inarticulate species swim for up to a month and have wide ranges.
