Squid Dissection Specimen for Biology Labs | Preserved Cephalopod Anatomy Specimen (8–12 Inch)

This preserved squid dissection specimen (8–12 inches) is a high-quality cephalopod specimen ideal for studying invertebrate anatomy, marine biology, and advanced organ systems in middle school, high school, and homeschool science programs. Squid are fascinating marine animals that provide students with the opportunity to examine specialized structures used for movement, feeding, sensing the environment, and survival. Each specimen is preserved to maintain excellent anatomical visibility and is individually packaged for classroom or at-home dissection activities.

Squid Anatomy Structures (External):
• Mantle
• Fins
• Head
• Eyes
• Siphon (funnel)
• Arms
• Tentacles
• Suckers
• Mouth
• Beak
• Chromatophores (when visible)

Squid Anatomy Structures (Internal):
• Gills
• Branchial hearts
• Systemic heart
• Digestive gland
• Stomach
• Cecum
• Intestine
• Ink sac
• Gonads
• Esophagus
• Mantle cavity

This preserved squid specimen supports instruction in marine biology, cephalopod anatomy, invertebrate zoology, and comparative anatomy, making it an excellent addition to biology laboratories and homeschool science studies. Students can explore how squid are uniquely adapted for life in the ocean while examining complex organ systems and specialized anatomical features.

Specimens are individually vacuum-sealed. Initially preserved in formaldehyde to fix tissues, specimens are then rinsed with water and packed in a low-odor, non-toxic holding solution.

Did You Know? Squid have three hearts—two pump blood to the gills, while a third pumps oxygen-rich blood throughout the body. This unique circulatory system helps support the squid's active lifestyle and powerful swimming ability.

Store specimens at room temperature away from direct sunlight. Do not freeze or expose to temperatures above 85°F. Unopened specimens will last 12 months. After opening, place the specimen in a zip-top bag and keep for up to one month.
