Five key factors contributing to the decline of fish species in the ocean include overfishing, which depletes fish populations faster than they can reproduce; habitat destruction, such as coral reef degradation and coastal development; pollution from agricultural runoff and plastic waste, which harms marine ecosystems; climate change, leading to ocean warming and acidification that disrupts fish habitats; and invasive species that outcompete native fish for resources. Together, these factors create a challenging environment for fish species to thrive.
Two abiotic factors of the ocean that are conditions of the environment are temperature and salinity. These factors can affect the distribution of marine species and influence ocean currents and circulation patterns.
Shells are biotic factors in the ocean because they are derived from living organisms, such as mollusks or crustaceans. They play a role in the ecosystem by providing habitat for other organisms and contributing to nutrient cycling.

Whales. (And I believe you mean "What is a non-native species to the ocean?")
The Indian Ocean is home to a diverse range of shark species, including the tiger shark, great white shark, hammerhead shark, and whale shark. Other notable species include the bull shark, reef sharks, and various types of ground sharks. These sharks inhabit different environments, from coastal waters to deeper oceanic regions. The unique ecosystems of the Indian Ocean support these various species, contributing to their ecological roles and biodiversity.

if you mean species of fish in the ocean, there is over 6 million diffrent species.
The largest extinction of species occurred during the Permian-Triassic period, approximately 252 million years ago. This event, known as the "Great Dying," is estimated to have wiped out about 90-96% of marine species and around 70% of terrestrial vertebrate species. Factors contributing to this mass extinction included volcanic eruptions, climate change, and ocean anoxia. It marked a significant turning point in Earth's biodiversity and set the stage for the rise of the dinosaurs in the subsequent Mesozoic era.
Invasive species can disrupt ocean ecosystems by outcompeting native species for resources, disturbing habitats, and introducing new diseases. This can lead to a decline in biodiversity, changes in food webs, and loss of valuable marine resources. Invasive species can also negatively impact human activities such as fishing and tourism.
Dusky piperfish is a fish species that lives in the Atlantic Ocean. Derwent flounder is a fish species that lives in the Pacific Ocean. Deepwater dab is a fish species that lives in the Atlantic Ocean.
There are 72 different species of Tangs in the ocean. They are classified based on their feeding guilds.
