🐸African clawed frog
Afrikankynsisammakko eli kynsisammakko (Xenopus laevis) on vedessä lähes koko elämänsä viettävä sammakko. Sadekautena se nousee maalle ja kuivan kauden koittaessa kynsisammakko kaivautuu mutaan odottamaan sateita. Kynsisammakkonaaras kasvaa jopa 13 cm:n mittaiseksi. Kynsisammakoiden selkä on ruskea tai harmaa ja niiden vatsa on vaalea. Albiinot kynsisammakot ovat vaaleanpunaisia. Sen tunnusmerkkinä on ommelta muistuttavat valkoiset juovat kummassakin kyljessä. Se muodostuu tuntoaistielimistä, jotka tuntevat veden värähtelyn. Siten sammakko havaitsee mutaisessa vedessä vaanivat viholliset ja paikantaa mahdollisen ravinnon. Pienissä eturaajoissa on kolme kynnellistä varvasta. Vahvoissa takaraajoissa on pitkät räpylävarpaat, minkä ansiosta afrikankynsisammakko on taitava uimari. Pienet silmät osoittavat ylöspäin mahdollistaen havaitsemaan sitä uhkaavat saalistajat. Vartalo on litteä ja virtaviivainen.
