4 Major Groups of Fish
Jawless, Cartiliginous, Lobe-Finned, Ray-Finned
Jawless Scales
Lacks Scales
Cartilignious Scales
Placoid
Lobe- Finned Scales
Ganoid
Ray-Finned Scales
Ctenoid & Cycloid
Dermal TIssues
Not Derivded from Epidermal Tissues
Ovuliparity
Female Lays Unfertilized Eggs, Externally Fertilized by the Male < Most Bony Fish>
Oviparity
Mother deposits internally fertilized eggs that develop and hatch outside of mother’s body
Ovoviviparity
Internally Fertilized eggs that are retinaed in oviduct and develop without any Nourishment from the mother
Viviparity
Yuong Develop in mother’s Uterus and are nourished by the mother before being born < Live Birth: Some shark and Bony FIsh>
Anadromous
Live in Ocean but Freshwater to Spawn
Ammocoets
Lmaprey Larvae
Hagfish Characteristics
Lacks scales, jaws, paired appendages, true eyes, stomach, but has barbels around mouth
Lamprey Metamorphosis
Their Whole Digestive system must be reconstructed
Gnathostomata
Jawed Vertebrates from Skeletal supports of the pharyngeal slits
Jaws Used for
Utilization of different food types
Facilitated Radiation and diversification
Chondrichthyes Characteristics
Placoid, Buoyant Livers, Spiral Valve Intestine
Ampulae of Lorenzini
Helps sense electrical fields given by the preys
Claspers
Transfer Sperm during internal fertilization
Two branches of Chondrichthyes
Elasmobranchii (Sharks, Skates, Rays) : 5-7 Gill opening, Rigid Dorsal Fin, upper jaw free from skull
Holocephali (Chimeras): Gills covered over a single gill opening, Soft Dorsal Fin with Spine infront, upper jaw fused to skull
Epipelagic Zone
Where light penetrates enough for photosynthesis
Shark Sizes
Great White Shark: 20ft , 4200 lbs
Hammer Head Shark: 18ft, 1000 lbs
Leopard Shark: 6.5 ft, 40 lbs
Whale Shark: 40ft, 47000 lbs
Skates vs Rays
Tiny, None, DIvided into 2 Lobes, Ovioarus / Oviviparous
vs
None, Near the End of the Tail, 1 Lobe, Ovoviviparous
Mermaids Purse
Big Skate Oviparous Eggs
Spiracles
Allows them to breathe while burrowed in Sand
Euryhaline
Can Withstand Variety Range of Salinity
Rostral Organ
Electro-Receptive Device
