So I assumed there were 'claws with digits' and claws without. In fact, legs terminate either with claws, or with digits + claws. As for getting the order right... that was a fluke!Reprobushttps://www.blogger.com/profile/10650084661969561056noreply@blogger.comtag:blogger.com,1999:blog-5460788270738656369.post-65916844735058828422010-10-20T17:54:21.281+08:002010-10-20T17:54:21.281+08:00For example, in spiders with comb-like structures ...<i>For example, in spiders with comb-like structures on the tarsal claws, what do you call the individual spines of the comb?</i><br /><br />Teeth, normally. Even if there's only one tooth. However, the tardigrade papers that I read over while researching this post referred to the ventral 'tooth' on the outer claws of this genus as a 'spur'.Christopher Taylorhttps://www.blogger.com/profile/11075565866351612441noreply@blogger.comtag:blogger.com,1999:blog-5460788270738656369.post-2288084682732606822010-10-20T17:20:17.888+08:002010-10-20T17:20:17.888+08:00I'm mildly chuffed that I got the order right,...I'm mildly chuffed that I got the order right, because now I can reveal that I don't rightly know what a 'digit' in a claw is. Is it just a spur on the claw (i.e. nonmovable?). I am in doubt because I don't know if taxonomists use 'digit' in the same way for other arthropods. For example, in spiders with comb-like structures on the tarsal claws, what do you call the individual spines of the comb?Reprobushttps://www.blogger.com/profile/10650084661969561056noreply@blogger.com
