Which of these is the best choice for a swimmer caught in a rip current?

Never attempt to swim directly back to shore against the current; it is most likely moving faster than you could possibly swim. Instead, calmly tread water. If you’re a strong swimmer, swim toward the edge of the rip, into the waves or white water.

Which one of the following is a landform created by wave erosion?

Sea cliffs and terraces, sea stacks and caves.

Which organisms will most probably can be seen during a low tide on a tidal flat?

Fauna of tidal flats includes molluscs, worms, crustaceans, echinoderms and acorn worms. These organisms serve as food for wading birds (Miththapala, 2013).

Which statement best describes the natural state of sandy beaches quizlet?

Which statement best describes the natural state of sandy beaches? They are in a constant state of flux (erosion and deposition).

Which statement best describes the natural state of sandy beaches?

Which statement best describes the natural state of sandy beaches? They are in a constant state of flux (erosion and deposition).

Why do most animals on sediment covered shores burrow into the sand?

A thick exterior or exoskeleton helps protect creatures from being crushed. Some organisms can survive for long periods of time out of water. Burrowing is one of the most common adaptations in rocky intertidal zones. A thick exterior or exoskeleton helps prevent creatures from drying out.

Why does the direction of longshore current sometimes reverse in direction?

The longshore current can change direction because the waves that approach the beach typically come from different directions in different seasons. It primarily flows southward along both the Atlantic and Pacific coasts.

Why is a rip current called a rip current?

Rip currents form when waves break near the shoreline, piling up water between the breaking waves and the beach. One of the ways this water returns to sea is to form a rip current, a narrow stream of water moving swiftly away from shore, often perpendicular to the shoreline.

Why is it important to identify the two types of crust?

Explanation: The thin oceanic crust is composed of primarily of basalt, and the thicker continental crust is composed primarily of granite. The low density of the thick continental crust allows it to “float” in high relief on the much higher density mantlebelow.

Why is managed retreat used?

Managed retreat maintains natural shoreline dynamics and enables shoreline habitats to migrate inland as the shoreline erodes to prevent loss of wetlands and other intertidal areas.

Why is the coral reef important?

Coral reefs protect coastlines from storms and erosion, provide jobs for local communities, and offer opportunities for recreation. They are also are a source of food and new medicines. Over half a billion people depend on reefs for food, income, and protection.

Why must much of the benthic biomass rely on surface productivity?

Why must much of the benthic biomass rely on surface productivity? (Choose all that apply.) Much of the benthic community lies in a realm where sunlight does not reach. Much of the benthic community survives in areas where photosynthetic primary producers cannot survive. You just studied 4 terms!

How do clownfish protect themselves from predators?

In order to live among the anemone, clownfish protect themselves from nematocyst strikes. Nematocysts are harpoon-like stingers on the anemone’s tentacles used to capture prey and ward off predators.

Are clownfish extinct?

Clownfish are capable of living independently of anemones in the absence of predators, and are easily bred in captivity, hence their complete extinction is unlikely. However, extinction in the wild is possible, and indeed likely.

Are clownfish protected by law?

SAN FRANCISCO— The National Marine Fisheries Service announced today that the orange clownfish — a species popularized for a generation of children by the movie Finding Nemo — may warrant protection under the U.S. Endangered Species Act because of threats from global warming and ocean acidification.

Are there interaction among lions?

Male lions form cooperative coalitions which compete against other coalitions for exclusive access to female prides (Bygott, Bertram, & Hanby, 1979).

Can i have a dory fish?

Why You Should Not Buy A Royal Blue Tang Fish Like Dory. Unlike the orange clownfish that could be bred in captivity, Dory’s species can only breed in the wild. Scientists say they have failed to successfully produce a method of breeding blue tang fish in aquariums, despite more than a decade of trying.

Do anglerfish have any predators?

Humans are the main predator of anglerfish. They fish for them and once caught they are sold in markets as food in European countries.

Do sharks eat angler fish?

A gold Anglerfish biting Tiger shark. Anglerfish are high-level danger enemy fish in Hungry Shark Evolution and Hungry Shark World. The fish is edible to all sharks within the game; other than the Reef Shark, who is the only shark who can’t eat them.

Does the clownfish have any predators?

Great White Sharks and Great Barracudas are two of the predators that prey on clownfish. The Piscivores are well adapted to catch their small prey that live in the anemones.

How do angler fish catch their prey?

The deep sea anglerfish’s lure is filled with bacteria that make their own light. Using a muscular skin flap, a deep sea anglerfish can either hide or reveal its lighted lure. By pulsing the light and moving the lure back and forth, they successfully attract pelagic crustaceans, fishes, and other prey.

How do angler fish protect themselves?

The deep sea anglerfish has adapted in the way of skin color to protect itself from predators as well as to disguise itself while trying to catch prey. Anglerfishes are usually a grey or dark brown color which helps them to blend in with the ocean depths and to hide in dark places along the ocean floor.

How do clownfish pee?

A lot of fish get rid of the pee through an tiny opening, called a pore, that’s near their rear ends—and in some fish, waste also goes out through the skin or the gills. When a fish pees in a coral reef, the corals wave their tentacles around like tiny arms to grab nutrients from the pee and absorb them.

How do sea anemone catch prey?

Anemones have rings of tentacles surrounding their central mouth. Tentacles have specialised stinging cells called nematocysts. They use these to immobilise their prey so that the tentacles are then able to move the food into the mouth. The extending tentacles can also be used to catch passing food as it drifts past.

How do sea turtles protect themselves?

Most sea turtle species have a hard shell that helps protect them from predators. They are also very fast swimmers and are often able to evade danger. Leatherback sea turtles have a soft shell, but are so large that are only in danger from the largest predators (and man).

How does global warming affect clownfish?

The metabolism of clownfish – or anemonefish – decreases when their sea ‘homes’ are damaged by climate change, according to a new study.
