Study in Royal Society journal on first observation of giant squid in the wild

Proceedings of the Royal Society B: Biological Sciences

First-ever observations of a live giant squid in the wild by Dr. T Kubodera and Dr. K Mori (rspb.2005.3158) The giant squid, Architeuthis, is one of the most mysterious creatures in the deep-sea. This is the first-ever successful attempt to observe a live giant squid in the wild. Not only can we provide the first live images of Architeuthis, but we have also reported on the only data on the depth and behaviour of this species. The observed giant squid was estimated about 8 m in total length, and hunting at 900 m depth during the day. It attacked prey from a horizontal orientation with a pair of long tentacles and enveloped the prey within coiled tentacular ball.

Not so ancient: the extant crown group of Nothofagus represents a post-Gondwanan radiation by Dr LG Cook and Dr MD Crisp (rspb.2005.3219)

Nothofagus (southern beeches) have been considered the key group for understanding the distribution of plants and animals in the Southern Hemisphere for 150 years. These beeches were widespread across eastern Gondwana before the super-continent split up and most of their present-day distribution, separated by oceans, is thought to reflect that ancient connection. Using relaxed molecular clocks, calibrated with fossils, we have determined that much of the differentiation among present-day Nothofagus lineages took place after Gondwana broke up. Rather than being "ancient relicts", current species of Nothofagus appear to be the descendants of a single species that survived a major extinction.
