Natural Environment

What is a coral? Corals are small invertebrate animals that create the foundation of an ecosystem that supports thousands of other organisms, including humans. Corals are in a group of organisms called Cnidarians, and are closely related to jellyfish, anemones, and hydroids.

Sea cucumbers are important. Of the many marine organisms populating Guam’s waters, sea cucumbers (balate’), shown in Figure 1, remain important and unique creatures that provide a crucial cleaning service to the ocean. Many islanders may reminisce of a time when they played with balate’ with their friends and family on the beach.

Guam’s coral reefs and their decline. Coral reefs are among the most productive ecosystems on the planet. They contribute greatly to cultural identity, education and tourism, and support millions of people as major food sources.

Large animals that are well-known and beloved by the general public are typically referred to as “Charismatic Megafauna.” The term is most commonly used by conservationists to describe animals whose widespread appeal makes them useful for increasing environmental awareness and support.

Classification, appearance and local distribution. Pilot whales are in the dolphin family (Delphinidae), which is part of the oceanic dolphins. The name “pilot” was came from the thought that one whale piloted the group. They are widely distributed and are currently recognized as two types: short-finned and long-finned. Although there is some evidence that the short-finned type may be two or more species, they are still classified as one type. The long-finned pilot whales are usually found in colder temperate conditions, while the short-finned live in warm tropical waters.
