In 2004, Alaska Fisheries Science Center biologists began attaching light sensors to Bering Sea survey bottom trawls to evaluate the effects of light on fish catchability. In response to this, Orcas have developed many ways to try and conserve their heat. Generally, the higher the environmental temperature, the faster the embryo divided. Catchability is a measure of how efficiently fish are caught in nets. Orcas are top predators in the ocean food chain and have no natural predators themselves.Despite their popularity, there is still much we dont know about orcas.

In the wild, male orcas live to an average of 30 years (maximum 50-60 years) and 46 years for females (maximum 80-90 years). For example, clearer water allows more sunlight to reach submerged aquatic vegetation. Their approach provides a tool that expands possibilities for research in other regions.
