Document Summary
Lecture 6 the deep sea anglerfish + bioluminescence. These light producing organs are called photophores. Live in dark marine habitats: depth: 1000-2000m. Relatively few animals live in such habitats: the deeper you go, the fewer light is filtered out, 500m is already like late evening (no street lights, past the 1000m, it is 100% pitch black. Anglerfishes may not encounter other conspecifics for long periods of time: extremely hard to find a mate, humans have a hard time trying to find the males suggesting that they are rare to begin with. Very hard to research because humans will be crushed: research submarines are 290682906829068 and very few people have the opportunity to go down in these. Females are much larger than males: 5-10x bigger. Unique features: reduced muscle, no scales, very flattened and excess tissue is avoided so they won"t be crushed.
