One species of squid which lives in the depths of the Pacific Ocean does not bother to distinguish male from female when mating. At the dark depths where sight is limited, male and female squid look very similar, so males will mate with and attach sperm packets to any squid of the same species. Now that’s being opportunistic.
Did you know that life in the deep ocean doesn’t just stop at the sea floor? Scientist have found evidence that microorganisms are living miles below the ocean floor deep down in the sediment! That’s a lot of real estate for some very small creatures.
So little is still understood about our deep oceans. One study recently discovered that the deep ocean had 898 species in an area about half the size of a tennis court. Over half of these species had never been identified before by scientists, and that’s not even including all the microscopic organisms that can be found.
Hawaiʻian fishponds or loko iʻa, are a sophisticated method for raising a steady source of food that is accessible during storms and high surf when fishing can be dangerous. Perpetuating traditional fishpond practices is important to create more sustainable food resources in Hawaiʻi and ensure that such advanced cultural knowledge is not lost
Rip currents, narrow plumes of water flowing out to sea, can move as quickly as eight feet per second. While panicked swimmers often try to fight the current, the easier way to get out of a rip current is to swim parallel to shore until the current releases you, and then swim back to land.

These reef communities provide essential habitat for fish and invertebrates and may play an important role in preserving biodiversity. The depth at which these reefs exist (beyond the photic zone) may offer a “refuge” from disturbance and stress as compared to shallower reef environments. However, this depth poses a challenge for marine researchers in collecting and observing the biological communities. Until the development of... (more)
