D. ingens, also known as the giant blue squid, is a deep-sea cephalopod found in the Pacific Ocean. It is notable for its vibrant blue color, large size reaching up to 13 feet, and its bioluminescent capabilities. It plays a crucial role in the deep-sea food web.

The species D. ingens, commonly known as the Kauri tree, is native to the North Island of New Zealand. It is primarily found in the northern regions, with dense populations in Northland, Auckland, and the Coromandel Peninsula.

D. ingens thrives in subtropical to temperate climates with high humidity and well-drained soils. The tree typically grows in lowland to mid-altitude forests, often forming dense stands in its native range. It requires ample rainfall distributed throughout the year, with temperatures ranging from mild to warm.

D. ingens is a dominant canopy tree in its native forest ecosystems, providing critical habitat and resources for numerous plant and animal species. It plays a significant role in forest structure and dynamics, contributing to biodiversity and ecological stability. The species is adapted to survive in regions with occasional disturbances such as storms, which open up gaps in the forest canopy, allowing for regeneration and growth.
