1 Please arrive 30 minutes before your program. Teachers and chaperones must be present during the staff-facilitated 45-minute program. Introduction. 1 Background Information Adaptation Scavenger Hunt Science Standards.. 4 To have the best adventure possible, please abide by all safety precautions posted and given by our staff. For information on SEA LIFE Aquarium and our education programs, visit From Interstate 5 Buses: Exit Palomar Airport Road East. Turn LEFT onto The Crossings Drive, and LEFT into the LEGOLAND parking lot. Cars: Exit Cannon Road East and turn RIGHT on LEGOLAND Drive. Dissect a real squid using kid safe equipment Learn the appropriate tools needed for the investigation Compare and contrast the external and internal anatomy Critically examine the specialized structures that allow squid to survive in the open ocean Explore squid hunting methods Review characteristics of Invertebrates Write your name in squid ink! Over 300 types of squid exist, including the giant squid, which can grow to almost 1000 pounds!

2 0 Squid belong to Phylum Mollusca, which also includes the gastropods (snails) and bivalves such as clams. Squid differ from other mollusks by the lack of an outer shell. Their body is composed of a soft outer section and an inner shell. Squid also belong to a group of animals called Cephalopods. Squid emerged during the Cambrian period 500 million years ago. At that time, thousands of types of Cephalopods existed; this has decreased to the four remaining Cephalopods that exist today, squid, nautilus, octopus, and cuttlefish. Squid have many adaptations to survive in the marine environment. This versatility allows them to survive from the deep sea to surface waters in coastal areas. Squid range in size from one inch to over 65 feet! The body consists of eight arms and two tentacles. The tentacles are longer than the arms and are used for catching and grasping prey. Rows of suckers line the arms, and suction cups are only present on the tips of the tentacles. Some squid even have claw-like hooks to combine power with the suckers! The mouth is in the center of the arms and a beak aids in capturing prey. Cephalopods are regarded as one of the most intelligent invertebrates and have a well-developed brain. Some Cephalopods are even capable of solving complex problems and believed to have long-term memory. When compared to other fish, the squid brain is well developed in proportion to the body size. In addition, the nervous system is also well developed. Dive into the underwater world of Cephalopods! Explore this invertebrate s anatomy as you explore from the inside out! Gather with the SEA LIFE staff to discuss the Cephalopod world. In groups, locate and identify major external and internal features and organs of a squid. Understand and use basic dissection techniques and terms. Critically examine the functions of several squid features and organs and their adaptations.

3 1. The main defense for an is to hide from predators. Secondary defenses include changing the color and texture of their skin, ejecting a thick cloud of ink, or swimming away quickly. Like squid, octopus use jet propulsion to move if they feel threatened. Observe the Giant Pacific Octopus. Is it using jet propulsion? 2. can change the color and texture of their body to match the surroundings. Observe the Giant Pacific Octopus. Is it using camouflage? Does its appearance change as you watch? 3. have different kinds of teeth depending on where they find food and what they eat. Compare mouths on the Zebra sharks and the Reef sharks. What kinds of food would they eat? Where are the mouths located? Watch our dive show to find out! 4. have flat bodies that allow them to camouflage in their surroundings. Their mouth and gills are found under their body, but they also have spiracles (holes) on their head to help them breathe if they are on the ocean floor. Pick a ray to watch in the Ray Lagoon. Can you locate the ray s mouth when it swims by? Can you find its spiracles? 5. can also change color to match their surroundings. In addition, they have a prehensile tail to help them hold on to their environment. Observe the Pacific Seahorse in the Kingdom of the Seahorse. What animal does their tail look like?

4 Adaptations in physical structure or behavior may improve an organism s chance for survival. 3.a. Students know plants and animals have structures that serve different functions in growth, survival, and reproduction. 3.c. Students know living things cause changes in the environment in which they live, some of these changes are detrimental to the organism and some are beneficial. 3.e. Students know that some kinds of organisms that once lived on Earth have completely disappeared and that some of those resembled to others that are alive today. All organisms need energy and matter to live and grow. 2.b. Students know producers and consumers are related in food chains and food webs and may compete with each other for resources in an ecosystem. Living organisms depend on one another and on their environment for survival. 3.b. Students know that in any particular environment, some kinds of plants and animals survive well, some survive less well, and some cannot survive at all. 2. Plants and animals have structures for respiration, digestion, waste disposal, and transport of materials. 2.a. Students know many multicellular organisms have specialized structures to support the transport of materials. 2.b. Students know how blood circulates through the heart chambers. Organisms in the ecosystem exchange energy and nutrients among themselves and with the environment. 5.a. Students know energy entering ecosystems as sunlight is transferred by producers into chemical energy through photosynthesis and then from organism to organism through food webs. 5.b. Students know matter is transferred over time from one organism to others in the food web. 5c. Students know populations of organisms can be categorized by the functions they serve in an ecosystem.

5 3-LS1-1 Describe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction and death. LS-1.B: Growth and Development of Organisms Reproduction is essential to the continued existence of every kind of organisms. Animals have unique and diverse life cycles. 3-LS2- Some animals form groups to help members survive. LS2.D: Social Interactions and Group Behavior Being a part of a group helps animals obtain food, defend themselves and cope with changes. Groups may serve different functions and vary dramatically in size. 3-LS4-2. Variations in characteristics among individuals of the same species may provide advantages in surviving, finding mates, and reproducing. 3-LS4-3 In a particular habitat some organisms can survive well, some survive less well and some cannot survive at all. 4-LS1-Animals have internal and external structures that function to support survival, growth, behavior and reproduction. LS2.A Interdependent Relationships in Ecosystems Organisms are related in food webs in which some animals eat plants for food and other animals eat the animals that eat plants. Organisms can only survive in environments in which their particular needs are met. A healthy ecosystem is one in which multiple species of different types are each able to meet the needs in a relatively stable web of life. MS-LS1-4. Characteristic animal behaviors affect the probability of successful reproduction of animals. LS2.B: Food webs demonstrate how matter and energy are transferred between producers, consumers and decomposers. LEGO, the LEGO logo, and LEGOLAND are trademarks of the LEGO Group The LEGO Group.
