Marine Biology Exam #2 Review Questions and Answers | Latest 2026
Update
Q: What drives evolution more quickly-- sexual or asexual reproduction?
Answer:
Sexual Differences between carnivores, omnivores, and herbivores Carni= meet
Omni= both Herb= both Suspension Feeding Feeding on particles of organic matter
suspended in the water Deposit Feeding Feeding on small specks of organic matter
that have drifted down and settled on the bottom Filter Feeding Sieves small food
items from water. Two requirements for a vertebrate - Vertebrate Skull (not
necessarily a bone) Three classifications for marine fish - Agnatha (jawless)
Chondrichthyes (cartilaginous fish) Osteighthyes (bony fish) Hagfish - Feeds on dead
and dying fish and marine animals Produce lots of mucous in glands to protect them
Jawless Lamprey - Also jawless
, Q: Not slimy
Answer:
parasites on other organisms
Cartilaginous vs bony fish Cartilaginous
teeth-like scales
gills exposed to environment
cartilege skeleton
mouth on underside
gills exposed to the environment
electric signal pickup
Bony
bony skeleton
plate-like scales
Mouth in front
plate covers gills
Lateral Line Series of pores and canals lined with neuromasts that are specialized to
detect
VIBRATIONS
Electric Sensors Detect living prey by sensing their neurons
Ovipary Egg laying
Viviparious Live birth
Oviviparous Kept inside of mother in an egg until right before hatching
