Video of Colossendeis megalonyx behavior around egg mass

This video shows the behavior of an adult of Colossendeis megalonyx around a recently-deposited egg mass from a mating group of the same species. The egg mass is indicated by a white circle and label that appears close to the beginning of the video. The adult can be seen manipulating the egg mass with its ovigerous legs (long, with scoop at the end) and palps (shorter). Next to the adult and egg mass are two other Colossendeis in mating posture. The video was taken by Graham Lobert on November 1, 2021 on a GoPro Hero Black at a timelapse rate of one frame per second, played back at 30 fps. The egg mass is approximately three cm across the short diameter.本视频记录了巨长脚海蛛（Colossendeis megalonyx）成体在同种交配集群新近产下的卵团周边的行为表现。视频开篇附近出现的白色圆圈与标注即指向该卵团。可观测到该成体凭借其抱卵肢（修长，末端带有勺状结构）与触肢（相对更短小）对卵团进行操控。在该成体与卵团旁，另有两只处于交配姿态的巨长脚海蛛。本视频由Graham Lobert于2021年11月1日使用GoPro Hero黑色版拍摄，延时摄影帧率为每秒1帧，回放帧率设定为30 fps。该卵团的短径约为3厘米。
