Data for: Reduced tenacity during “high-speed” territorial encounters in the intertidal owl limpet, Lottia gigantea: Agonistic escalation increases risk of wash-off.

79 measurements of limpet tenacity in the context of behavior and speed.
Speed is in cm per min. Animals showing Continued Foraging assigned speed of 0.2 cm per min (see Wright 1982)
Response.
0-Continued Foraging: Subject moves < 1 shell length in 90 s, or turns less than 90 degrees in 90s; Cephalic tentacles visible throughout 90s.
1-Retreat behavior: Subject turns more than 90 degrees away from bait limpet, and moves > 1 shell length during 90s test period.
2-Territorial behavior: Subject accelerates toward bait limpet, moving > than one shell length during 90s test period.
Sl- Shell length in mm.
Tenacity-Newtons required to remove subject from substratum divided by its aperture area.
ApArea- Limpet aperture area, calculated from Shell Length (see Materials and Methods)

本数据集包含79项帽贝附着力的测量数据，涵盖行为与运动速度两个维度。
运动速度单位为厘米/分钟。处于持续觅食状态的个体，其运动速度被赋值为0.2厘米/分钟（详见Wright 1982）。

响应类别：
0-持续觅食：受试个体在90秒内移动距离小于1倍壳长，或在90秒内转向角度不足90度，且90秒内始终可见头部触手；
1-逃逸行为：受试个体转向远离诱饵帽贝的角度超过90度，且在90秒测试期内移动距离大于1倍壳长；
2-领地行为：受试个体向诱饵帽贝加速移动，且在90秒测试期内移动距离大于1倍壳长。

Sl：壳长，单位为毫米。
Tenacity（附着力）：将受试个体从基底移除所需的牛顿力值，除以其壳口面积所得的比值。
ApArea：帽贝壳口面积，通过壳长计算得到（详见材料与方法部分）。
