caudal

The scientists found that giving this molecule to mice activated the caudal nucleus of the solitary tract, or cNST, which is tucked inside the brainstem.

These findings indicated that the "caudal forceps," which is a major characteristic of Dermaptera, and the "elaborate maternal care for eggs and young larvae," which are an important behavioral trait in this order, have emerged in parallel.

"Additionally, developmental changes suggest that vertebral anatomy shifts across development to support a larger body and caudal fin."

After running numerical simulations, Ito and his team were able to replicate the synchronization of caudal fins and demonstrate that it results in a significant reduction in energy dissipation for a pair of fish at distances shorter than half a body-length.

"They work in tandem to utilize the reverse-Kármán vortex street and adjust their caudal fins accordingly."
