Shrimp goby with its partner shrimp

Metallic shrimp goby (Amblyeleotris latifasciata) with its partner, an alpheid shrimp. This goby lives in a symbiotic association with the shrimp. The shrimp digs a burrow in which they both live. The shrimp is blind, however, and relies on the goby to know when it is safe to emerge to feed. It does this by keeping an antenna permanently in contact with the fish. The pair live on sandy seabeds around coral reefs in the tropical waters around South-East Asia. Photographed in Indonesia

Leaf veins of the common ivy

Scanning electron micrograph, tinted green, of a leaf skeleton of the common ivy, Hedera helix. The skeleton is left after the soft tissue (mesophyll) has rotted away, & consists of the vascular tissue (veins) of the plant: the xylem, which carries water & minerals from the roots, & the phloem, which takes sugar from the leaves to the rest of the plant. The xylem cells are impregnated with lignin, a polymer resistant to decay & hence surv- iving to form the skeleton. In dicotyledonous plants (with two seed- leaves) the vascular system is a network of increasingly small veins, as here. Magnification: X 4 (35mm). Original is BW print B745/032
