Spider wasps paralyse and eventually kill their hosts, but are considered parasitoids, not predators.. At the most basic level, predators kill and eat other organisms. However, the concept of predation is broad, defined differently in different contexts, and includes a wide variety of feeding methods; moreover, some relationships that result in the prey's death are not necessarily called pre
Prior to the advent of industrial whaling, great whales may have been the major food source for orcas. The introduction of modern whaling techniques may have aided orcas by the sound of exploding harpoons indicating the availability of prey to scavenge, and compressed air inflation of whale carcasses causing them to float, thus exposing them to ...
This fall, a hearty run of chum salmon drew the pod of killer whales to Puget Sound waters, she said. The whale with a salmon on its head was almost assuredly getting enough to eat at the time ...

Tahlequah, the killer whale who carried her dead calf and swam with him for 17 days in 2018, has likely suffered another loss.. Per The Seattle Times, researchers believe the mother orca's newborn ...
Orcas in the Gulf of California appear to have gained special skills to hunt and kill the world’s largest fish, according to a new study.. Whale sharks, which grow up to 18m long, are known to ...
In comparison, the modern killer whale has teeth around 8 cm (3.1 in) in height and 2.5 cm (0.98 in) in diameter. [3] Like the modern killer whale, the tooth lacks a coat of cementum. However, unlike the modern killer whale, O. paleorca had a circular tooth root as opposed to an oval, and the pulp extended more towards the back than the front. [2]
The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.
