- Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all tetrapods excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant (living) amphibians belong to the monophyletic subclass Lissamphibia, with three living orders: Anura (frogs and toads), Urodela (salamanders), and Gymnophiona (caecilians). Evolved to be mostly semiaquatic, amphibians have adapted to inhabit a wide variety of habitats, with most species living in freshwater, wetland or terrestrial ecosystems (such as riparian woodland, fossorial and even arboreal habitats). Their life cycle typically starts out as aquatic larvae with gills known as tadpoles, but some species have developed behavioural adaptations to bypass this.
- Elizabeth Siddal (Wikipedia)
Elizabeth Eleanor Siddall (25 July 1829 – 11 February 1862), better known as Elizabeth Siddal (a spelling she adopted in 1853), was an English artist, art model, and poet. Siddal was perhaps the most significant of the female models who posed for the Pre-Raphaelite Brotherhood. Their ideas of female beauty were fundamentally influenced and personified by her. Walter Deverell and William Holman Hunt painted Siddal, and she was the model for John Everett Millais’s famous painting Ophelia (1852). Early in her relationship with Dante Gabriel Rossetti, Siddal became his muse and exclusive model, and he portrayed her in almost all his early artwork depicting women.
