Fiddler crab eyes have numerous other specializations for their unusual lives, reviewed by Zeil and Hemmi (2006).
Among placental mammals, there are numerous cochlear specializations which relate to hearing range in adaptation to specific habitats that are superimposed on a common basic design.
Less obvious but especially significant are numerous skull features, specializations of the Weberian apparatus in otophysans, configuration of the swim bladder, and fusions of vertebral elements.
The intercalation theory now proposes a benthic, deposit-feeding gastraea as the bilaterian ancestor with a direct development, and with planktotrophic larvae evolving independently in numerous lineages through specializations of juveniles.
It is well known that spiral ganglion neurons are selectively responsive to specific sound frequencies, and that numerous structural and physiological specializations in the inner ear increase the quality of this tuning, beyond what could be accomplished by the passive properties of the basilar membrane.
This implies that the larval types are important phylogenetic markers and not just isolated specializations with numerous complex homoplasies.
The capacity for true quadrupedal terrestrial locomotion in Mystacina is a secondarily derived condition, reflected in numerous skeletal and muscular specializations absent in other extant bats.
From professional and strategic marketing, to attribution modeling, to multi-channel campaign tools, as well as more self-serve front ends that allow organizations to easily automate nurture drips and campaign workflows, email delivery and the ability to connect it to other parts of the business remains a specialization that numerous companies are more than happy to outsource.
The axons traverse the sub-ependymal layers and show many varicosities, local swellings containing numerous vesicles but without synaptic specializations, suggesting local non-synaptic release mechanisms [ 11, 68, 73- 76].
