Teeming rocks bring biology to life

The Biology Department and some 250 Year 12 Biology students went to Waiake in Torbay to collect data by counting organisms for their internal assessment on 19 February.

The rocks were teeming with life in different zones, from columnar barnacles and black nerite in the high tide zone, plicate barnacles, top shells, oysters and predatory oyster borers in the mid tide zone and cat’s eyes in pools or in the low tide zone. We saw crabs and cucumbers too, hiding in rockpools.

Neptune’s necklace and coralline turf was strewn across the intertidal zone like lost jewellery. The day was hot and the packed lunches were tasty before our bus ride back to school.
