List of living brachiopod species. The following is a taxonomy of extant (living) Brachiopoda by Emig, Bitner & Álvarez (2019). There are over 400 living species and over 120 living genera of brachiopods classified within 3 classes and 5 orders, listed below. Extinct groups are not listed. [1]The lophophore anatomy of Yuganotheca also indicates that it may not have had a real brachiopod-like, laminar filter-feeding organ, directed laterally through the lophophore as in all living brachiopods, but rather had a more phoronid-like filtration system with the current directed towards the mouth (Fig. 3).Extract. Over a decade has passed since Rudwick (1965b, 1970) and Ager (1967) reviewed the ecology of brachiopods, a hiatus partially filled by Brunton (1975) and Steele-Petrovic (1979). With the widespread use of SCUBA, we are finally beginning to learn about these dominantly subtidal (both Recent and fossil) organisms in their proper environment.

the inarticulate brachiopods and the articulate brachio-pods. Some of the oldest shelly invertebrate fossils known are brachiopods. They have a fossil record stretching back to the start of the Cambrian Period, some 570 million years ago (Table 1). Brachiopods are still living in the world’s oceans. Brachiopods live only in the sea, and most species avoid locations with strong currents or waves. 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. See more

For example, brachiopods utilize a range of larval development strategies (Thayer 1981; James et al. 1992;Peck and Robinson 1994) that cannot be inferred directly for extinct species in most cases ...Living brachiopods are sensitive to sudden changes in illumination, and avoid light generally, preferring cryptic environments. Brachiopod flesh is bad-tasting and avoided by potential predators. Refer to lab for details of valve morphology.
