Antimora rostrata with copepod parasite Okeanos 2013

Summary

During a deep-sea dive, the team encounters a rare sight: an antimora fish with a parasitic copepod on its forehead, similar to a previous observation. Dr. Amanda Demopoulos expresses excitement, as such occurrences are uncommon and challenging to document. The copepod's morphology, resembling TV antennas, is intriguing, with variations in size and appearance noted, including one engorged to the size of a golf ball. The dive also reveals other marine life, such as eels, red crabs, and burrows.

Q & A

What was the subject of excitement for Dr. Amanda Demopoulos during the dive?

Dr. Amanda Demopoulos was excited about observing a deep-sea fish with a parasitic copepod, as such observations are rare.

Why are observations of deep-sea fishes with parasites considered rare?

Observations of deep-sea fishes with parasites are rare due to the difficulty in capturing them on video, as mentioned in the script.

What was the specific species of fish with a parasitic copepod observed during the dive?

The specific species of fish with a parasitic copepod was an antimora, as mentioned in the script.

What is a copepod, and how does it relate to the script?

A copepod is a type of small crustacean that can act as a parasite. In the script, it is observed parasitizing a specific species of antimora fish.

How does the morphology of the copepod observed in the script compare to what is typically seen?

The copepod observed in the script had a morphology that looked like TV antennas, which is different from the usual golf ball-sized appearance mentioned in the script.

What was the significance of the copepod's location on the fish's body?

The copepod was observed on the forehead of the antimora fish, which is an interesting location and might suggest a specific preference or adaptation by the parasite.

What was the size of the engorged copepod mentioned in the script?

The engorged copepod mentioned in the script was about the size of a golf ball.

How does the appearance of the engorged copepod differ from its normal state?

In its engorged state, the copepod was almost unrecognizable, suggesting a significant change in appearance when it is full compared to its normal state.

What other marine life was observed during the dive besides the antimora with a copepod?

Other marine life observed during the dive included eels, red crabs, and several burrows.

What does the term 'fully engorged' imply in the context of the copepod?

The term 'fully engorged' implies that the copepod has fed to its maximum capacity, likely having taken in a large amount of blood or other nutrients from its host.

What was the team's previous experience with observing copepods on fish?

The team had previously observed the same species of fish with a copepod, indicating a pattern or recurring phenomenon.
