AN AUSTRALIAN ECHIDNA WALKS ACROSS A TRACK IN SYDNEY

An echidna, native to Australia, casts a shadow as it walks over a track in
Sydney's Taronga Zoo August 4, 2003. Scientists say that the echidna, which
has been called a freak of nature, has often been the victim of mistaken
identity with the hedgehog and North American spiny porcupine but is in fact
one of the world's clearest examples of Convergent evolution - the emergence
of chance look-alikes. FOR RELEASE WITH FEATURE

Bread mould, SEM Featured 4 Aug 2003 Print

Bread mould, SEM

Bread mould. Coloured scanning electron micrograph (SEM) of a sporangium of a bread mould (Rhizopus stolonifer). Spores develop in these sac-like bodies, or sporangia (globular structure). The mould spores then circulate freely in the air, which germinate a network of hyphae (threads) if they land on a favourable medium. Their function is to absorb food for growth and for spore production. Rhizopus sp. produces stolons, or aerial hyphae, which on contact with the medium grow rhizoids (rootlets). These anchor the mould and absorb water. Magnification: x700 at 10x8 inch size
