Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Tissue and cellular organization of the planula larva of the reef-coral Pocillopora damicornis are detailed ultrastructurally. Emphasis is placed on fine structure of the aboral (=presumptive calicoblast) epidermis. The pre-settling exploratory behavior of the coral larva is discussed. The aboral epidermis consists of a tall columnar epithelium, made up of a heterogeneous cell population-nematocytes, secretory and mucus cells, and flagellated cells. Basally, the columnar epithelium is modified into complexly interdigitating cellular processes, appearing as a discrete histological layer. A-type granules (Jha and Mackie, 1967) indicate neurosecretory activity. The flagellated cell contains a peculiarly comlex flagellar apparatus, including a new intracellular structure, an electron-opaque fibrous cup. It extends across the entire width of the flagellated cell apically, enveloping the flagellar basal bodies and paired transverse accessory rootlets. The flagellum main basal rootlet passes freely through an opening in the base of the rootlet cup. The flagellated cell is here viewed as a sensory cell, as suggested by the corona of microvilli encircling the flagellum, the bundles of microvilli, and extensive areas of tight junctions with adjacent cells. There is no evidence in the gastrodermis or epidermis of the planktonic larva for pre-settling accumulation of calcareous skeletal material. Vesicles containing a highly oriented fibrous material may represent sites of skeletal organic-matrix precusor buildup. © 1974 Springer-Verlag.
