Problem: Extract the answer to the question from the following context. Question: What spiny animal might you find on the reef? Context: The marine life found here consists of anemones, urchins, sea cucumbers, and eels, which all live on the reefs along with turtles, conch and many varieties of marine fishes.

Other species of fish which are recorded close to the shore line in shallow waters are: sergeant majors, the blue chromis, brown chromis, surgeon fish; blue tangs and trumpet fish. On the shore are ghost crabs, which always live on the beach in small burrowed tunnels made in sand, and the hermit crabs, which live in land but lay eggs in water and which also eat garbage and sewerage. They spend some months in the sea during and after the hatching season.

Problem: Extract the answer to the question from the following context. Question: When does the mismatch times occur?

A: summer
