Box jellyfish
Although the notoriously dangerous species of box jellyfish are largely restricted to the tropical Indo-Pacific region, various species of box jellyfish can be found widely in tropical and subtropical oceans, including the Atlantic Ocean and the east Pacific Ocean, with species as far north as California ("Carybdea confusa"), the Mediterranean Sea ("Carybdea marsupialis") and Japan (such as "Chironex yamaguchii"), and as far south as South Africa (for example, "Carybdea branchi") and New Zealand (such as "Copula sivickisi").
Quillback rockfish
Quillback rockfish live along the Pacific coast from the Gulf of Alaska to the northern Channel Islands of Southern California. Like other rockfish species, quillbacks live on the bottom, perching on rocks or hiding in rock crevices. The juveniles stay mainly along the shore, in reefs, sand and eelgrass, while the adult rockfish live in the deeper waters. They are for the most part solitary dwellers, rarely being found in groups. They are rarely found in the open ocean, generally preferring to stay close to kelp, rocks, coral, or lodged in crevices or holes. Despite this, they are not territorial. High densities tend to coincide with peak plant growth. They occupy a variety of habitats in many different areas on the west coast of North America.
