Why does a fish in water appear closer to the surface than it actually is?

A fish in water sees an object which is 33 cm above the surface of water. The apparent height of the object as noticed by the fish is [Take  nw=43𝑛𝑤=43 ]

Paragraph 3: Creatures living in the upper part of the mesopelagic, where light intensities arehigher, are more likely to be transparent. Zooplariktor that penetrate the deeper levels of themesopelagic are commonly orange, red, or purple but in the blue-green background light areperceived as black or inconspicuous gray. Some mesopelagic fish have elongate (long and narrow)bodies, which may be a means of extending the length of the lateral lire—a vibration-detectingorgan—thereby raising sensitivity for detecting predators or prey.1. According to paragraph 3, which organisms are likely to be transparent?A: Those that are not good at detecting preyB: Those that live in places where the light is blue-greenC: Those with elongate bodiesD: Those that live in the brighter part of the mesopelagic zone

Within the Actinopterygii (bony fish) lineage, marine teleosts (bony fish with mobile jaws) live in an aquatic environment where there is a higher external concentration of salt and a lower concentration of water relative to their internal concentrations.  Owing to these conditions, salt ions tend to diffuse into the teleost through its skin, whereas water molecules within the organism osmotically traverse the opposite path.Irrespective of lineage, many fish species actively assess their environment and regulate their internal concentration of fluids and electrolytes via a homeostatic process known as osmoregulation.  Teleosts with either glomerular kidneys (eg, eels, sculpin) or aglomerular kidneys that are purely tubular (eg, goosefish, toadfish) have served as experimental subjects for the study of marine teleost osmoregulation.  Analyzing the ionic (ie, Na+, Cl−, Mg2+, SO42−) concentration of intestinal fluids, urine, and plasma in each species led to the discovery that the renal tubule of the goosefish has both excretory and reabsorptive functions.Scientists have concluded that marine teleost osmoregulation involves the ingestion of seawater, retrieval of salts and water from the intestine, and primary excretion of divalent ions via urine and monovalent ions through the gills (thin barriers between the organism's blood and the aquatic environment).In an experiment to further study osmoregulatory mechanisms, researchers emptied the gut of an eel and sealed the anus to prevent anal fluid loss.  The eel was transported into seawater that had been treated with the volume marker phenol red, which can only be excreted anally.  After 20 hours, the eel's gut contained 2.3 mL of fluid but showed a phenol red concentration equivalent to 12.3 mL of ingested seawater.  Researchers found that the eel excreted 2.3 g of urine.  They ultimately reported that the eel had lost all the seawater it absorbed through the gut via various mechanisms. Question 55Which of the following conclusions about the eel can be made based on the experiment in the passage?  (Note:  Water density is 1.0 g/mL.)A.The eel absorbed 12.3 mL of water through the gut.B.The eel drank 10.0 mL of water.C.The eel lost 7.7 mL of water extrarenally.D.The eel excreted 4.6 mL of water renally.
