Marine final Flashcards
marine plant can fix nitrogen and photosynthesize but the two processes do not occur in the same region
Cyanobacteria
The life cycle that typifies Rhodophyta and is advantageous to increase successful fertilization within this group that lacks flagellated spores
Approx life cycle
True or False: Chlorophyta can be filamentous, unicellular, or parenchymatous in form
True
Seagrasses are a polyphyletic group that all
exhibit what type of pollination.
Hydrophily
Group 1: two unequal flagella & commonly from symbiotic relationships
Dinophyta
Group 2: cell walls of silica, used in forensics
Bacillariophyta
Group 3: members of Phaeophycea that
have an intercalary meristem (in addition to apical and basal meristems) & are ecosystem engineers
Laminariales
Group 4: scaly coat, haptonema, calcification
Haptophyta
At the phyla level- I have a radula, mantle, & foot
Who am I?
Mollusca
My cell are pluripotent and my body is home to many small reef organisms.
I have calcareous spicules but not siliceous ones.
Class Calcarea in Phylum Porifera
I am part of the plankton. I have tissue grade construction. The beating of my ctenes is controlled in part by sensing of balance with a statocysts at my crown
Phylum Ctenophora
Unsegmented worm with a Rhyncoelum
What is Phylum Nemertea
I have an oral and aboral side a madreporite and a respiratory tree and when I get upset cuverian tubules are eviscerated.
Class Holothuroidea
Head-foot with beak
Class Cephalopoda
Jointed legs with a book gills
Subphylum Chelicerata
These pores are used to secrete salt so mangroves can live
along the coast
lenticels
Nephridia are used for what function
What is removal of wastes
Amebocytes are used for what function in Porifera
Transport nutrients/production of new cells
structure found in bivalves that is used to sort food particles to the esophagus
labial palps
structure holds algae to the substratum
holdfasts.
structure is used for jet propulsion in Cephalopoda
siphon.
The function of this structure in polar bears is block cold water from coming close to the body
guard hairs.
The function of this structure is gas exchange and is found in the carapace of decapod crabs
Ctenidia.
In cruising fishes like the tuna this protein within the muscles allows for constant swimming
myoglobin
Sea otters are members of what order?
Order Carnivora
Ear flaps, hind region that can be rotated underneath the body, loud vocalizations
Sea lions
This group of marine mammals has solid long bones with little or no bone marrow and are herbivores
Order Sirenia (Family Dugongidae)
This group within the Infraorder Cetacea has one dorsal blowhole, tend to be smaller
And includes Sperm whales, orcas, dolphins, beaked whales, pilot whales, narhwal
Odontocetes
Internal structure in nasal canal that vibrates involved in echolocation
phonic lips
Barycardia, slowed metabolism, flexible lungs are all adapations that allow for what function.
deep prolonged dives
This group of pinnipeds has air sac under its throat which acts like a flotation bubble and allows it to bob vertically in the wate
walruses
True or False: A square tail in Osteichthyes is best used for maneuverability
True
These two groups feed on seagrass and are vertebrates
Order Sirenia & Green Sea TurtleS
Class Scyphozoa reproduces sexually where the benthic polyp undergoes a process called ________.
strobilation
Chondrichthyes males reproduce with structures called?
Claspers
This type of feeding is seen in Humpback whales where they create a net of bubbles around prey to scare them to the center and swim up in it with their mouth open
Bubble net feeding
Salps and lancelets filter feed with what structure?
Pharyngeal baskets
Brachiopoda and Bryozoa feed with a structure called a __________.
Lophophore
Whale vomit highly prized for its use in perfumes
and other products
amber-gris
water vascular system in echinoderms and describe it
coelomic water vascular system, the system consists of a central ring canal and radial canals extending along each arm
sensory systems in fishes. What is a lateral line and how does it function? How do some fish sense electrical signals?I
detect, track, and discriminate their prey, as well as negotiate their environment
echolocation in Odontocetes
