This document summarizes research on shark and skate vision and sensory biology. It discusses studies that have examined the visual fields, binocular overlap, spectral sensitivity and temporal resolution of various shark and skate species. The research aims to understand how the sensory capabilities of elasmobranchs relate to their habitats and behaviors. It also provides context on the economic and ecological importance of the Indian River Lagoon, where much of the sensory research is conducted.

Fiji Butterflyfish Presentation at FICSFStuart Gow
The 2009 inaugural Fiji Islands Conservation Science Forum (FICSF) provided an excellent platform for the Butterflyfish Count organizing committee to present its findings to the greater scientific and conservation organizations in Fiji as well as to the general public. The presentation was made by Chinnamma Reddy on behalf of the committee.
A presentation that discusses the ecological, ethical and health costs of consuming shark fin soup. While this presentation was designed for high school students in British Columbia, Canada, it can be modified to suit other age groups and other regions. However, there are some graphic images that may not be suitable for younger audiences.
Shark introduction Morphology and its behaviour characteristicsArubSultan
Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the Batoidea (rays and kin). Some sources extend the term "shark" as an informal category including extinct members of Chondrichthyes (cartilaginous fish) with a shark-like morphology, such as hybodonts. They generally do not live in freshwater, although there are a few known exceptions, such as the bull shark and the river shark, which can be found in both seawater and freshwater.Sharks have a covering of dermal denticles that protects their skin from damage and parasites in addition to improving their fluid dynamics. They have numerous sets of replaceable teeth.

❑ Snapper fish belong to the family
Lutjanidae and are widely distributed in
tropical and subtropical waters around
the world.
❑ Characterized by their streamlined
bodies, large eyes, and sharp canine
teeth
❑ They play a crucial role in marine
ecosystems as both predators and prey.
▪ Snapper species vary in size, with some
reaching lengths of over three feet and
weights exceeding 50 pounds
many snapper species are commonly found in
shallow coastal waters at depths ranging from 10 to 100
meters.
▪ Some species can inhabit deeper offshore environments
exceeding 200 meters.
Morphology of snapper fish
1. Body Shape and Size:
Have sleek, torpedo-shaped bodies that are laterally compressed.
Small species measuring a few inches to large species reaching
several feet in length.
2. Jaws and Teeth:
Their mouths are typically terminal.
Carnivorous snapper species often have conical teeth for grasping
and puncturing prey
Omnivorous species may have more flattened teeth for crushing
shells or grinding plant material.
3. Fins and Scales: several fins contribute to their locomotion,
stability.
Two dorsal fins, one near the head
another closer to the tail, along with anal,
Pectoral, and pelvic fins
Covered in overlapping scales
That provide protection against abrasion,
Predators, and pathogens.
Conclusion
Snapper fish stand out as prized species in the realm of seafood,
cherished for their delectable taste, firm texture, and vibrant colors.
Their streamlined bodies and sharp teeth reflect their predatory nature,
Play a vital roles within marine ecosystems.
Their popularity among anglers and consumers has led to concerns
regarding overfishing and habitat degradation, prompting the
implementation of management measures to ensure their long-term
sustainability.
Despite these challenges, the allure of snapper fish persists, captivating
both culinary enthusiasts and conservationists alike with their culinary
excellence and ecological significance.
