Add mention of Lobopodian claws

Busy working on other articles, but I think someone should make a section that briefly mentions the claws of Velvet worms, Tardigrades, and maybe Lobopodians as a whole. All of these have structures called claws which are morphologically distinct from the pincers of arthropods, looking much more like a traditional claw RenaMoonn (talk) 22:57, 28 March 2025 (UTC)

Lissamphibian claws

Claws or claw-like structures are largely absent from lissamphibians, as they exhibit a minimally cornified epidermis. Despite this, hard, cornified integumentary structures resembling amniote claws in general appearance are present in some lissamphibian species. The hynobiid salamanders Onychodactylus japonicus and Onychodactylus fischeri have claws on both fore- and hindlimbs. The sirenid salamander Pseudobranchus striatus lacks hindlimbs but has claws on all four digits of the forelimbs. Among anurans, pipids are the only group known to possess claws. In the two genera with claws, Xenopus and Hymenochirus, the claws appear as black cone-shaped caps on the tips of the first three pedal digits. The general anatomy of these structures in Xenopus laevis was recently described and hypotheses relating to their growth presented (Maddin et al. 2007). Based on differences in both the anatomy and the inferred pattern of growth, Maddin et al. (2007) suggested that the claws of X. laevis evolved independently of those of amniotes. 147.251.148.182 (talk) 09:28, 28 April 2025 (UTC)

I think it should be given the Integumentary system Category

claws are part of the Integumentary system, so I think it should be added to that category Gabsofthelake (talk) 18:39, 7 March 2026 (UTC)
