The Surinam toad catches prey by entraining large volumes of water for ingestion and by limiting fish escape with its fingers. It uses bidirectional suction, a process the frog initiates by depressing its hyoid and retracting its clavicle. The amount of entrained water the frog can ingest is related to its ability to actively increase its body ...
The common toad, European toad, or in Anglophone parts of Europe, simply the toad (Bufo bufo, from Latin bufo "toad"), is a toad found throughout most of Europe (with the exception of Ireland, Iceland, parts of Scandinavia, and some Mediterranean islands), in the western part of North Asia, and in a small portion of Northwest Africa.

The common name "marine toad" and the scientific name Rhinella marina suggest a link to marine life, [32] but cane toads do not live in the sea. However, laboratory experiments suggest that tadpoles can tolerate salt concentrations equivalent to 15% of seawater (~5.4‰), [ 33 ] and recent field observations found living tadpoles and toadlets ...
The toad is able to absorb water from the surrounding soil; even as the soil becomes increasingly dry in spring and early summer months, increased concentrations of urea in the toad's body allow it to continue to suck water out of the soil through osmosis. When the summer rains arrive the Great Basin spadefoot emerges from its burrow.
Bufo is a genus of true toads in the amphibian family Bufonidae.As traditionally defined, it was a wastebasket genus containing a large number of toads from much of the world but following taxonomic reviews most of these have been moved to other genera, leaving only seventeen extant species from Europe, northern Africa and Asia in this genus, including the well-known common toad (B. bufo).
