How does a mussel find a host fish? They don’t have eyes to see, but mussels have special adaptations to bring the host fish to them. Western North American species of mussel can release glochidia in a clump (called a conglutinate) that looks like decaying flesh- an attractive food source to fish.
Does a clam have eyes?
How many eyes does a clam have? Giant clams have been reported to possess several hundred small pinhole eyes, which are also known as hyaline organs on the exposed mantle. Clam eyes are light-sensitive and allow them to detect changes in light levels.
Does a jellyfish have a brain?
Jellyfish have no brain! They have a basic set of nerves at the base of their tentacles which can detect touch, temperature, salinity etc. Since they don’t have a brain, they depend on automatic reflexes in response to these stimuli! Catching prey is also a matter of chance.
How do starfish think?
Instead of one central brain, starfish have a series of neural plexi, or nerve nets. These are like interconnected miniature brains that run different parts of the body while communicating with each other.
Do sea urchins eat kelp?

Are kelp crabs found in a kelp forest?
Kelp bass, giant kelpfish, garibaldi, norris’ top snail, and kelp crabs are all common inhabitants of the kelp forest. Kelp anchors to the rocky bottom with a structure called the holdfast. The holdfast has many crevices and is home to many other animals such as spiny brittlestars and amphipods.
Do dolphins live in the kelp forest?
Many larger animals, such as grey whales, sun fish, sea lions and dolphins, use the kelp forest to forage or as a screen of protection against raging seas, swift currents and tumultuous tides.
Do sea cucumbers eat kelp?

Do sea otters need kelp?

Sea urchin feeding strategy: natural selection has produced urchins with powerful jaws so they can eat large quantities of kelp. Their impact on kelp forests can be great if the population is high.
Do snails eat kelp?
Invertebrates that eat kelp include snails and shellfish such as crabs, sea urchins and abalone. These shellfish are themselves eaten by other creatures. For instance, in the Pacific Ocean off the West Coast of the United States, sea otters eat a lot of abalone.
Does kelp use photosynthesis or cellular respiration?
Kelp, like most autotrophs, creates energy through a process called photosynthesis. An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals.
How do otters eat sea urchins without getting hurt?
Quickly spinning the sea urchin in her paws, she breaks off the prickly spines. Using her teeth, she chomps open the body and licks out the insides. The sea otter’s high metabolic rate helps them to stay warm – to fuel it each day, they have to eat 20-30% of their body weight in food!
How do sea otters help kelp?
The presence of sea otters can protect a kelp forest. They eat large amounts of sea urchins, which keeps the creature’s numbers in check and prevents the destruction of the kelp forest. Sea otters are a keystone species of the coastline ecosystem.

Kelp are large brown algae that live in cool, relatively shallow waters close to the shore. They grow in dense groupings much like a forest on land. These underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
What does seaweed do for fish?
Tropical fish have evolved to digest aquatic based veggies more so than we humans typically eat. Seaweed and other aquatic based algaes are best for both tropical and marine fish and they can help improve the immune system and offer anti-inflammatory benefits also.
What is destroying the kelp forest?
More than 95 percent of California’s coastal kelp forests have been killed by an explosion of purple sea urchins. Commercial divers like Byron Koehler and Gary Trumper have been hired to help control the purple urchin population.
What is the function of a stipe?
The stalk or stem of seaweed is called a stipe. The function of the stipe is to support the rest of the plant. The structure of the stipe varies among seaweeds; they can be flexible, stiff, solid, gas-filled, very long (20 meters), short, or completely absent.
