Captive bred common frog tadpoles ( rana temporaria  )
 
The common frog  is one of only 2 native frog species in the UK (the rare pool frog being the second) common frog tadpoles are larger and lighter in colour than toad tadpoles they are also more secretive and tend to hide more.
Common frog eggs are laid in large clumps as opposed to toad spawn which is  laid  in long strands ,the tadpoles also get larger  and are lighter in colour than toad tadpoles while they look similar after hatching , frog tadpoles turn a sandy brown color whereas toad tads stay dark black ,unlike toad tads which are usually seen in large groups swimming out in the open this is due to them being toxic and highly distasteful to ,fish ,birds and mammalian predators although newts will sometimes eat them and their toxins dont deter insect predators at all  ,this is why toads prefer to breed in larger bodies of water with higher fish populations and less aquatic insects in contrast to frogs which prefer smaller water bodies with no fish ,as the frog tadpoles lack of toxins makes them vulnerable to vertebrate predators like fish and birds , their higher speed and agility is enough for them to evade most insect predators.
