Scientists have identified several new marine species in a pristine underwater ecosystem recently discovered in international waters -- and they expect to find more. Modern technology that allows ...
The authors found that "a small but growing number of studies sought to develop automated species identification systems based on morphological characters". An overview of 20 studies analyzing species' structures, such as cells, pollen, wings, and genitalia, shows identification success rates between 40% and 100% on training sets with 1 to 72 ...
Unfortunately, this is an invasive species in the home aquarium and is unsuitable for reef systems and refugiums. Its prickly thallus is fragile and easily breaks up into fragments that can develop into new individuals once they settle. [159] 1 in (2.5 cm) [160] Bird-Nest: Chondria sp.
