A new species of sponge-dwelling amphipod, Polycheria spongoteras sp. nov., from Spirits Bay, Northland, New Zealand.

A new species of the often-cryptic genus Polycheria (Crustacea; Amphipoda) was discovered living in a small specimen of the sponge, Homaxinella erecta (Brøndsted, 1924) (Demospongiae, Suberitida, Suberitidae), in Spirits Bay, on the northern tip of the North Island of New Zealand. Polycheria spongoteras sp. nov.

A new deep-water species of Myopiarolis Bruce, 2009 (Crustacea: Isopoda: Serolidae) from New Zealand waters.

Myopiarolis tona sp. nov. is described from the Challenger Plateau, southern Lord Howe Rise and the west coast of the North Island, New Zealand at depths of 634-1250 m.

Mechanisms explaining nursery habitat association: how do juvenile snapper (Chrysophrys auratus) benefit from their nursery habitat?

Nursery habitats provide elevated survival and growth to the organisms that associate with them, and as such are a crucial early life-stage component for many fishes and invertebrates. The exact mechanisms by which these benefits are afforded to associated organisms, however, are often unclear. Here we assessed potential explanations of the nursery function of structurally complex habitats for post-settlement snapper, Chrysophrys auratus, in New Zealand.
