Final answer:
Squids have arms and tentacles with an ink gland as external features that help them in their predatory life.
Step-by-step explanation:
Two external features that are adaptations for the predatory life of squids are their arms and tentacles, and their ability to produce ink.
The arms and tentacles of squids have chitin zed rings, which help them catch and hold onto prey. These structures are essential for their hunting and feeding behavior, allowing them to capture and manipulate their prey.
Squids also have an ink gland located between their gills, which can be released as a cloud of ink into the water. This ink serves as a defensive mechanism, creating a distraction to confuse and escape from predators.
