What part of the crab is like a built in fork?

The claw

This scientific term describes an animal feeding on living coral tissue, mucus, or skeleton.

Corallivory

This red crab is Ariel’s musical friend in The Little Mermaid.


Sebastian

These corals grow upward in thin, tree-like branches

branching corals

Repeated feeding on a coral can reduce this basic measure of how quickly a colony gets larger.

coral growth

200

What surface is the crab repeatedly picking material from while feeding.

The reef surface/substrate

200

If a crab removes and consumes living coral tissue, the crab is the consumer and the coral plays this ecological role.

Prey

200

Tamatoa, the giant treasure-loving crab, appears in this Disney movie.


Moana

200

These massive corals form rounded shapes that can look a bit like giant underwater boulders

massive corals

A feeding wound can expose coral skeleton and create space that may later be colonised by organisms such as these photosynthetic reef competitors.

algae

300

What plant like plant-like material is removed while feeding?

Algae/Algal

300

Unlike a rock or plant, a coral colony is actually made up of thousands of these tiny animals.

coral polyps

Mr. Krabs owns this restaurant in SpongeBob SquarePants

Krusty Krab

300

These corals form broad horizontal surfaces resembling dinnerware

plate/table corals

300

If a coral repeatedly spends energy repairing feeding wounds, it may have less energy available for producing these.What are eggs and sperm / reproduction?

eggs and sperm / reproduction

400

By removing algae or other material, crabs feeding can influence competition for this limited reef resource.

Space

400

When coral tissue is removed, the colony must redirect energy and cellular resources toward this process instead of growth or reproduction.

Wound healing / tissue regeneration?

400

This famous crab is a miserly restaurant owner obsessed with money

Mr. Krabs

400

These corals have distinctive winding ridges and valleys that resemble a human organ.

brain coral

400

If corallivores consistently prefer some coral species over others, their feeding can eventually alter this feature of the reef.

coral community composition

500

One crab’s breakfast seems tiny, but repeated feeding by many reef animals can help shape this larger ecological feature.

Reef/Benthic community

500

Coral feeding does not always involve breaking the skeleton. Some crabs associated with corals primarily consume this energy-rich substance continuously produced by the coral.

coral mucus

500

What is this pokemon called


Krabby
500

What is the actual scientific name of this coral 


Acropora

500

Heat stress, pollution and coral feeding can act together, meaning a feeding injury may be more difficult for a coral to recover from when it is already experiencing this general condition.
