The oceanic zone is the vast open part of the ocean where animals such as whales, sharks, and tuna live. The benthic zone consists of substrates below water where many invertebrates live. The intertidal zone is the area between high and low tides. Other near-shore (neritic) zones can include mudflats, seagrass meadows, mangroves, rocky ...
The whale shark (Rhincodon typus) is a slow-moving, filter-feeding carpet shark and the largest known extant fish species. The largest confirmed individual had a length of 18.8 m (61.7 ft). [8] The whale shark holds many records for size in the animal kingdom, most notably being by far the most massive living non-cetacean animal.
They have inhabited our oceans for more than 500 million years, pre-dating the first dinosaurs by 100 million years, [6] and they appear in every single ocean, playing a crucial role in the health of the marine ecosystems. [7] Due to threats such as overfishing, climate change, habitat loss and persecution, many shark populations have declined ...
“Sharks of the Dead Zone,” which premieres at 9 p.m. Friday as part of Discovery’s Shark Week, sounds a bit frightening.And it is, if you care about the health of our planet. The host of the ...
Changes in marine ecosystem dynamics are influenced by socioeconomic activities (for example, fishing, pollution) and human-induced biophysical change (for example, temperature, ocean acidification) and can interact and severely impact marine ecosystem dynamics and the ecosystem services they generate to society. Understanding these direct—or ...
Marine biology is the scientific study of the biology of marine life, organisms that inhabit the sea.Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.
"Sharks inhabit pretty much every ocean, every sea, every marine environment on the globe, so if you're speaking to kids, it's about them paying attention to what's happening in and around the ...
[11] [13] Sharks are also killed for their flesh in Europe and elsewhere. [14] The 2007 film Sharkwater documents ways in which sharks are being hunted to extinction. [15] In 2009, the IUCN Shark Specialist Group reported on the conservation status of pelagic (open water) sharks and rays. They found that over half the pelagic sharks targeted by ...
