Cloudinomorphs were one of the few groups to survive from the Ediacaran into the Cambrian, but they are known only from their external tubes. Here, Schiffbauer et al. report soft-tissue preservation of cloudinomorphs; the internal structures are inte

The fossil record of the terminal Ediacaran Period is typified by the iconic index fossil Cloudina and its relatives. These tube-dwellers are presumed to be primitive metazoans, but resolving their phylogenetic identity has remained a point of conten

Teinopalpus aureus (Lepidoptera: Papilionidae) is endemic to the mountains of southern China and Vietnam. This butterfly species was the focus of several high profile poaching cases in China and influenced conservation policies in the country because

By controlling the traction between its body and the tube wall, a tube-dwelling polychaete can move efficiently from one end of its tube to the other, brace its body during normal functions (e.g., ventilation and feeding), and anchor within its tube

We apply new perspectives on how organisms burrow by examining the association of in situ variation in sediment mechanical properties with burrowing ability and species distribution of two sympatric lugworms, Abarenicola pacifica and Abarenicola clap

The fact that sand dollars are often dislodged and inverted is an inescapable consequence of living at or slightly below the sediment–water interface. Once inverted, however, how do sand dollars effectively right themselves, given their small spine

Mud fiddler crabs, Uca pugnax, have a streak of blue coloration located on the front of the carapace above the mouth and centered between the eyes. We documented that this blue streak is absent in juveniles and develops as crabs become sexually matur

Synopsis In this article we review the phylogenetic distribution of major chaetal types within the Polychaeta, discuss what has been demonstrated about chaetal function in modern worms, and examine what is known about the evolution of chaete through

We tested the hypothesis that hooked setae function as anchors in three species of tubiculous polychaetes (Eudistylia vancouveri, Schizobranchia insignis, and Owenia fusiformis). All maintained position within their tubes when exposed to high pressur

To address the functional contributions of capillary chaetae in the maldanid polychaete Clymenella torquata, we compared irrigation efficiency and tube structure for animals with intact and trimmed capillary chaetae. We measured pumping rates for wor
