What is the economic importance of Hydra?

Answer. Due to its immortality, Hydra has been the subject of many studies regarding aging processes for several years. Hydra is an important model for studies of axial patterning, stem cell biology and regeneration. The genome of Hydra magnipapillata has been sequenced and compared to the genomes of other animals.

Why are coral reefs economically important?

Coral reefs supportjobs, tourism, and fisheries. Healthy coral reefs support commercial and subsistence fisheries as well as jobs and businesses through tourism and recreation. Approximately half of all federally managed fisheries depend on coral reefs and related habitats for a portion of their life cycles.

Cnidarians contain specialized cells known as cnidocytes (“stinging cells”), which contain organelles called nematocysts (stingers). These cells are present around the mouth and tentacles, serving to immobilize prey with toxins contained within the cells. Nematocysts contain coiled threads that may bear barbs.
