The Evolution of Schooling In filter-feeding ancestors, before vision and the OLS had developed, the risk of predation would have been limited. The OLS probably evolved from a primitive system of epidermal ciliated sensory receptor cells, presumably mechanoreceptors (Baker et al., 2008; Streit, ...
Among the 12 morphotypes, Morphotype 6 (Fig.2a–e) is particularly noteworthy for its resemblance to the flank scales of osteichthyans. Two features in particular stand out: rhomboid shape and articulations to the median dorsal scales and ventrally adjacent scales via an arrangement evocative of ...
We investigated, for the first known time, the evolution of spore size within three phylogenetic clades, Ceratomyxa, Sphaerospora sensu stricto and Parvicapsula. We found that spores from elasmobranch-infecting myxozoans were on average 4.8× (Ceratomyxa), 2.2× (Parvicapsula clade) and 1.8×...
Aquatic animals have developed effective strategies to reduce their body drag over a long period of time. In this work, the influence of the scales of fish on the laminar-to-turbulent transition in the boundary layer is investigated. Arrays of biomimetic

A Devonian tetrapod-like fish and the evolution of the tetrapod body plan The relationship of limbed vertebrates (tetrapods) to lobe-finned fish (sarcopterygians) is well established, but the origin of major tetrapod features has... Edward,B.,Daeschler,... - 《Nature》 被引量: 475发表: ...
next to older teeth, and the whorls are asymmetrical, which strongly implies that each one formed along either the left or right jaw of the creature. Based on the whorls’ features, the teeth’s most likely bearer was a new type of cartilaginous fish, which the study namesQianodus...

We refer to the habitat as the most dominant feature accountable for the environment structural complexity44, which can originate both from geological...
8a to d). This supports our argument that the global patterns of rarity we uncover are not simply a response to traits influenced by local features. In conjunction with a trait correlation analysis (Supplementary Fig. 9a and b), this shows that no single trait was unduly influential on the...
