This study, by examining the presence, localisation and colocalisation of serotonin, substance P, PGP 9.5 and tubulin, wants to demonstrate the sensory role that these structures play in the ecology of the Green whip snake Hierophis viridiflavus (Lacépède, 1789). Leer más.
The beak utilized in tadpoles of R. dalmatina for crushing vegetables is formed of cornified cell layers. A row of large wedge-like cells forms a central pile that produces the sharp corneous lamina of the beak. The labial and oral surfaces of the beaks also accumulate corneous material during proliferation and differentiation of keratinocytes from the epidermis to form a sheath around the central corneous cells.

I tested for the correlation between the extension of the dark colouration and several morphological traits (body size, head size and limb length) in the gecko, as well as parasitism by mites and age. No relationship was found between dark colouration and parasitism, age and limb length, but the extension of the dark colouration was positively correlated with head size controlled for body size.
