Furca fossils have been found in sediments indicative of shallow marine habitats. Since appendages and other body parts are unknown, no firm conclusions can be made of the biology of Furca. However, comparisons to other marrellomorphs and living arthropods such as horseshoe crabs suggest a benthic marine lifestyle: dwelling on the sea floor. [2]
The furcula, or furca is a forked, tail-like appendage. It is present in most species of springtails , and in them it is attached ventrally to the fourth abdominal segment. The organ most often is present in species of Collembola that lives in the upper soil layers where it is used for jumping to avoid predators. [ 1 ]
For example, a mid-stream island of soil or silt in a delta is most likely temporary, due to low material strength. A location where a river divides around a rock fin, e.g. a volcanically formed dike , or a mountain, may be more lasting as a result of higher material strength and resistance to weathering and erosion.
When the shield is carried on the tip of the abdomen, it is secured to a double-lobed, spine-like process called the caudal furca, [6] which is also known as the "anal fork". [7] The larva constructs the shield by maneuvering its "muscular telescopic and highly protrusible anus ", [ 8 ] or "anal turret", which is positioned dorsally, on the back.
The median home price in New York, for example, is $807,718. “Phoenix isn’t always simply low cost,” he said. “It’s developing hastily to its thriving tech and healthcare sectors.”
Depending on the definition, the telson is either considered to be the final segment of the arthropod body, or an additional division that is not a true segment on account of not arising in the embryo from teloblast areas as other segments. [1] It never carries any appendages, but a forked "tail" called the caudal furca may be present. The ...
