Large tadpoles, reaching lengths of 3-4 inches in some cases, are very
abundant in the temporary pools of East Africa. Late in the life of the
pools they can occur in shoals of hundreds, perhaps thousands of
individuals. They can be carniverous and are known to predate on each other,
so the odd slow-moving Notho would be easy pickings. When we find a pool
with a great abundance of these large tadpoles we generally don't waste too
much time looking for Nothos because their presence in abundance can almost
always be correlated with an absence of Nothos, even in known Notho
localities. The presence of a lot of tadpoles generally means that one is
too late - the Nothos have already come and gone.
